In decision-making structures, the programmer must define one or more conditions to be evaluated or tested by the program. And a statement or statements to be executed if the condition is determined to be true, and optionally, further statements to be executed if the condition is determined to be false.
The general form of a typical decision-making framework present in most programming languages is shown below.
Given below are the decision-making statements available in VB.Net:
|
Statement |
Description |
|
If ... Then statement |
“An If...Then statement consists of a boolean expression followed by one or more statements”. |
|
If...Then...Else statement |
An If...Then statement is followed by an optional Else statement, which gets executed when the Boolean expression is false. |
|
nested If statements |
If or Else if statement can be used inside another If or Else if statement(s). |
|
Select Case statement |
A ‘Select Case' statement is used to test a variable for equality against a list of values. |
|
