The VB.NET OrElse operator

In VB.NET and ASP.NET, the OrElse operator is a logical operator used with If statements to evaluate multiple conditions. The OrElse operator is like the Or operator but provides short-circuit evaluation. Short-circuit evaluation means the testing can stop after one condition evaluates to true.

The basic syntax for using the OrElse operator in an If statement is as follows:

If condition1 OrElse condition2 Then
   ' code to execute if either condition is true
End If

In the preceding example, the code block will be executed if either condition1 or condition2 is true. However, unlike the Or operator, the OrElse operator provides short-circuit evaluation, which means that if condition1 is true, condition2 will not be evaluated. Short-circuiting can improve performance when considering condition2 is expensive or time-consuming.

Here’s an example that demonstrates the use of the OrElse operator:

Dim var1 As Integer = 4
Dim...
