Control Statements in VB.NET Enum

In VB.NET, an Enum is a data type that consists of a set of named constants. Control statements are used to control the flow of execution in a VB.NET program. In this page, we will discuss control statements in Enum in VB.NET.

Syntax

The syntax for creating an Enum is as follows:

[Flags]Public Enum enum_name
    constant_1 = value_1
    constant_2 = value_2
    constant_3 = value_3
    ...
End Enum

Here is the syntax for using control statements in Enum in VB.NET:

Select Case enum_variable
    Case constant_1
        ' code to be executed if enum_variable = constant_1
    Case constant_2
        ' code to be executed if enum_variable = constant_2
    Case Else
        ' code to be executed if enum_variable is not equal to any predefined value
End Select

Example

Here is an example that demonstrates the use of control statements in Enum in VB.NET:

Enum Color
    Red
    Blue
    Green
End Enum

Dim selectedColor As Color = Color.Red

Select Case selectedColor
    Case Color.Red
        Console.WriteLine("The color is Red")
    Case Color.Blue
        Console.WriteLine("The color is Blue")
    Case Else
        Console.WriteLine("The color is not Red or Blue")
End Select

Output

The color is Red

Explanation

In the example above, we created an Enum called Color. We set the value of selectedColor to Color.Red. We then used a Select Case statement to check the value of selectedColor. Since the value of selectedColor is Color.Red, the first Case statement is executed, and the output is "The color is Red".

Use

Control statements such as Select Case are used to handle different scenarios based on the value of an Enum variable. This way, you can write code that handles all possible values of an Enum variable.

Important Points

• Enums in VB.NET consist of a set of named constants.
• Control statements such as Select Case are used to control the flow of execution in a VB.NET program and are often used with Enums.
• Control statements in Enum are used to handle different scenarios based on the value of an Enum variable.

Summary

In this page, we discussed the syntax, example, output, explanation, use, and important points of control statements in Enum in VB.NET. We learned that control statements such as Select Case are used to control the flow of execution in a VB.NET program and are often used with Enums to handle different scenarios based on the value of an Enum variable.
