An operator is a symbol (e.g., = , + , > , & ) that causes VB.NET to take an action. That action might be an assignment of a value to a variable, the addition of two values, a comparison of two values, concatenation of strings, etc.
In the previous sections, you’ve seen a number of operators at work. For example, the assignment operator ( = ) has been used to assign a value to a variable:
In the code shown above, the value 15 is assigned to the Integer variable myVariable. In the section on branching you saw more sophisticated operators, such as the greater-than comparison operator ( > ) used to compare two values:
The preceding If statement compares valueOne with valueTwo; if the former is larger than the latter, the test evaluates true, and the If statement executes.
The following sections will consider many of the operators used in VB.NET in some detail.
Mathematical Operators
VB.NET uses seven mathematical operators: five for standard calculations ( + , - , * , / , and \ ), a sixth to return the remainder when dividing integers ( Mod ), and a seventh for exponential operations ( ^ ). The following sections consider the use of these operators.
Simple arithmetic operators (+, -, *, /, \)
VB.NET offers five operators for simple arithmetic: the addition ( + ), subtraction ( - ), and multiplication ( * ) operators work as you might expect. Adding two numbers returns their sum, subtracting returns their difference, and ...

VB.NET Operators
This article covers the use of VB.NET operators.
Along with VB.NET Data types , Operators form the very base of the VB.NET language. These two topics are the first things anyone coming into this language should learn. Operators are used widely in numerous applications, along with numerous other statements such as loops. The most commonly used operators or Arithmetic, Assignment and comparison.
Arithmetic Operators
Arithmetic Operators in VB.NET are used to perform numerical calculations. Below are all the Arithmetic operations supported by VB.NET.
Comparison Operators
Comparison operators are used between two values or statements to determine a result. Below is the list of all the supported Comparison operations in VB.NET
Assignment Operators
Arguably the most common, Assignment Operators are used to assign values to variables. See the full list of Assignment operations below.
Logical Operators
Used to carry out logical operations on and between values in VB.NET such as and and or . Below is a full list of logical operators in VB.NET.
AndAlso and OrElse are almost identical to And and Or respectively. The difference is that And and Or can also be used as Bit-wise operators, whereas AndAlso and OrElse can only be used on Boolean Data. This distinction helps to avoid confusion in some cases.
Bit-wise Operators
Bit-Wise operations occur between binary numbers. The operators operate on each bit in the numbers individually, producing a single bit as output until all the bits have been acted upon.
Operators that act on a single number/value are called unary operators.

+= Operator (Visual Basic)
- 11 contributors
Adds the value of a numeric expression to the value of a numeric variable or property and assigns the result to the variable or property. Can also be used to concatenate a String expression to a String variable or property and assign the result to the variable or property.
variableorproperty Required. Any numeric or String variable or property.
expression Required. Any numeric or String expression.
The element on the left side of the += operator can be a simple scalar variable, a property, or an element of an array. The variable or property cannot be ReadOnly .
The += operator adds the value on its right to the variable or property on its left, and assigns the result to the variable or property on its left. The += operator can also be used to concatenate the String expression on its right to the String variable or property on its left, and assign the result to the variable or property on its left.
When you use the += operator, you might not be able to determine whether addition or string concatenation will occur. Use the &= operator for concatenation to eliminate ambiguity and to provide self-documenting code.
This assignment operator implicitly performs widening but not narrowing conversions if the compilation environment enforces strict semantics. For more information on these conversions, see Widening and Narrowing Conversions . For more information on strict and permissive semantics, see Option Strict Statement .
If permissive semantics are allowed, the += operator implicitly performs a variety of string and numeric conversions identical to those performed by the + operator. For details on these conversions, see + Operator .
Overloading
The + operator can be overloaded , which means that a class or structure can redefine its behavior when an operand has the type of that class or structure. Overloading the + operator affects the behavior of the += operator. If your code uses += on a class or structure that overloads + , be sure you understand its redefined behavior. For more information, see Operator Procedures .
The following example uses the += operator to combine the value of one variable with another. The first part uses += with numeric variables to add one value to another. The second part uses += with String variables to concatenate one value with another. In both cases, the result is assigned to the first variable.
The value of num1 is now 13, and the value of str1 is now "103".

Concatenation Operators in VB.Net
In VB.NET, there are several ways to concatenate strings, allowing you to combine multiple strings into one.
Using the & Operator
The & operator is the most common way to concatenate strings in VB.NET. To concatenate strings using the & operator, simply place the strings next to each other with the & operator, in between. For example, the following code concatenates the strings "Hello" and "World" to create the new string "Hello World":
Using the + Operator
The + operator can also be used for string concatenation.
Using String.Concat Method
The String.Concat() method is another way to concatenate strings in VB.NET. The String.Concat() method takes one or more strings as arguments and returns a new string that is the concatenation of the input strings.
The String.Concat() method is generally less common than using the & operator, but it can be useful in some cases, such as when you need to concatenate strings from a variable number of sources.
Using String.Format
You can use String.Format to concatenate and format strings.
Using Interpolation (VB.NET 14 and later)
String interpolation allows you to embed expressions inside string literals.
Using StringBuilder (for multiple concatenations in a loop)
When concatenating multiple strings in a loop, it's more efficient to use a StringBuilder to avoid creating new string instances repeatedly.
The & and + operators for simple concatenation. The String.Concat method for combining strings. String.Format for string formatting and concatenation. String interpolation (VB.NET 14 and later) for embedding expressions within strings. StringBuilder for efficient concatenation, especially when working with multiple concatenations in loops. Each of these methods has its own use cases, and you can choose the one that best suits your specific scenario for string concatenation in VB.NET.

Try the following example to understand all the assignment operators available in VB.Net −. Module assignment. Sub Main() Dim a As Integer = 21 Dim pow As Integer = 2 Dim str1 As String = "Hello! " Dim str2 As String = "VB Programmers" Dim c As Integer. c = a. Console.WriteLine("Line 1 - = Operator Example, _.
The following are the assignment operators defined in Visual Basic. = Operator ^= Operator *= Operator /= Operator \= Operator += Operator-= Operator <<= Operator >>= Operator &= Operator. See also. Operator Precedence in Visual Basic; Operators Listed by Functionality; Statements
The element on the left side of the equal sign ( =) can be a simple scalar variable, a property, or an element of an array. The variable or property cannot be ReadOnly. The = operator assigns the value on its right to the variable or property on its left. The = operator is also used as a comparison operator. For details, see Comparison Operators.
Overloading the & operator affects the behavior of the &= operator. If your code uses &= on a class or structure that overloads &, be sure you understand its redefined behavior. For more information, see Operator Procedures. Example. The following example uses the &= operator to concatenate two String variables and assign the result to the ...
2. First of all - you can't override assignment operator = ( Why aren't assignment operators overloadable in VB.NET? ). If you assign structure to new structure, you copy just value fields, reference fields will stay the same (thus your new MarbleCollection.marbles will point to same object as original MarbleCollection.marbles).
The assignment operators are: =. The equal operator, which is both an assignment operator and a comparison operator. For example: oVar1 = oVar2. Note that in VB .NET, the equal operator alone is used to assign all data types; in previous versions of VB, the Set statement had to be used along with the equal operator to assign an object reference.
Operators. An operator is a symbol (e.g., =, +, > , &) that causes VB.NET to take an action. That action might be an assignment of a value to a variable, the addition of two values, a comparison of two values, concatenation of strings, etc. In the previous sections, you've seen a number of operators at work. For example, the assignment ...
Here is an example of VB.Net arithmetic operator: Step 1) Create a new console application. To know this, visit our previous tutorial on Data Types and Variables. Step 2) Add the following code: Module Module1. Sub Main() Dim var_w As Integer = 11. Dim var_x As Integer = 5. Dim var_q As Integer = 2.
VB.Net - Operators - An operator is a symbol that tells the compiler to perform specific mathematical or logical manipulations. VB.Net is rich in built-in operators and provides following types of commonly used operators ? ...

The preceding example adds 1 to the value of n, and then stores that new value in n. It is a shorthand equivalent of the following statement: A variety of compound assignment operations can be performed using operators of this type. For a list of these operators and more information about them, see Assignment Operators (Visual Basic).
Assignment Operators There are following assignment operators supported by VB.Net: Show Examples Operator Description Example = Simple assignment operator, Assigns values from right side operands to left side operand C = A + B will assign value of A + B into C += Add AND assignment operator, It adds right operand to the left operand and assigns ...
Arithmetic Operators in VB.NET are used to perform numerical calculations. Below are all the Arithmetic operations supported by VB.NET. Sum of two numbers. Difference of two numbers. Product of two numbers. Division of two numbers, returns float value. Division of two numbers, returns integer value. (Decimal part removed)
This assignment operator implicitly performs widening but not narrowing conversions if the compilation environment enforces strict semantics. For more information on these conversions, see Widening and Narrowing Conversions.For more information on strict and permissive semantics, see Option Strict Statement..

X = 5, X assign a value 5 X = P + Q, (P + Q) variables or value assign to X. += An Add AND assignment Operator is used to add the value of the right operand to the left operand.
Miscellaneous Operators; Types of VB.NET Operators. These are some of the types of VB.NET Operators: For example: x = 2 + 3. Here, = and + are the operators and x, 2, 3 are the operands. The operator is working on some things, those things are known as an operand. VB.NET Operators are a rich set of operators that are available for use. 1 ...
In VB.NET, operator is a special symbol that tells the compiler to perform the specific logical or mathematical operation on the data values. The data value itself (which can be either a variable or a constant) is called an operand, and the Operator performs various operations on the operand. The symbol + and - are the Operators, and the 3, 2 ...
The & operator is the most common way to concatenate strings in VB.NET. To concatenate strings using the & operator, simply place the strings next to each other with the & operator, in between. For example, the following code concatenates the strings "Hello" and "World" to create the new string "Hello World": Dim str1 As String = "Hello" Dim ...
Assignment operators cannot be overloaded, but +=, for example, is evaluated using +, which can be overloaded. These operators cannot be overloaded. With the same conversion operators: ... public static explicit operator MyType1(MyType2 src) //explicit conversion operator. return new MyType1 { guts = src.guts }; Ticket closed as "Won't Fix" in ...
Here is the closest answer I personally could come up with: <System.Runtime.CompilerServices.Extension()>. Public Function Assign(ByRef Operand1 As Object, ByRef Operand2 As Object) As Object. Operand1 = Operand2. Return Operand1. End Function. Even though it allows you do do this, Dim a, b, c As Integer.
