ASP.NET razor VB logic

ASP.NET Razor - VB logical condition

Programming logic: Code is executed according to conditions.

If condition

VB allows code to be executed according to conditions.

Use the if statement to determine the condition. Based on the judgment, the if statement returns true or false:

• The if statement starts with a block of code
• The condition is written between if and then
• If the condition is true, if ... The code between then and end if is executed

Else condition

The if statement can contain the else condition.

The else condition defines the code that is executed when the condition is false.

Note: In the example above, if the first condition is true, the code for the if block will be executed. The else condition overrides "all cases" except the if condition.

ElseIf condition

Several conditions determine that the elseif condition can be used:

In the example above, if the first condition is true, the code for the if block will be executed.

If the first condition is not true and the second condition is true, the code for the elseif block will be executed.

There is no limit to the number of elseif conditions.

If neither the if and elseif conditions are true, the last else block (without conditions) overrides "all other cases."

Select condition

Select blocks can be used to test some individual conditions:

Select Case is followed by the test value (day). E ach individual test condition has a case value and any number of lines of code. I f the test value matches the case value, the corresponding line of code is executed.

The select block has a default case (Case Else), which overrides "all other situations" when all specified cases do not match.

The above is ASP.NET the use of Razor VB logical conditions.
