Syntax analysis of nested If statements in ASP. NET Programming

The use of if in ASP. NET programming is very common, so we hope to help you with the format and usage of nested If statements in ASP. NET programming. Next, let's take a look.

Nested If statement

The format is as follows:

 
 

  
  
If condition 1 Then
  
  
If condition 2 Then
  
  
Statement Block 1
  
  
Else
  
  
Statement Block 1-2
  
  
End If
  
  
Other statements
  
  
Else
  
  
Statement Block 2
  
  
End If
 
 

ASP. in the NET programming, the so-called nested if statement is that the statement block in the If condition is also a set of if conditions, and the statement block is a set of if conditions, so repeat until the condition setting is complete.

Generally, the most complex conditional statements are nested conditional statements. All the conditional statements mentioned above can form nested conditional statements. As long as the syntax concept is clear, understand the "class relationship" between each condition and the statement block. nested conditional statements are not difficult.

Multi-execution path statement

The format is as follows:

Select Case data/Expression

 
 

  
  
Case condition value 1
  
  
Statement Block 1
  
  
Case condition value 2
  
  
Statement Block 2
  
  
Case condition value 3
  
  
Statement block 3
  
  
Case condition value N
  
  
Statement Block N
  
  
CaSe ElSe
  
  
Statement Block N + 1
  
  
End Select
 
 

Multi-execution path refers to dividing the execution method of a program into multiple paths (the If statement has only two paths, I .e., whether the conditional statement is true or not ).

If the data or expression meets the condition value 1, execute statement Block 1. If the condition value 2 is met, execute statement Block 2. If the condition value 3 is met, execute statement Block 3, when the data or expression meets the condition value N, the statement Block N is executed. If all the condition values do not match, the statement Block N + 1 is executed.
