Conditional statements
The condition statement in VB.NET is still the if Then statement and the SELECR CASE statement.
IF THEN statement
The if Then statement is relatively simple, and the same rule is the same.
IF conditional statement example
Public Class Testa
Public Sub New ()
DIM B as Boolean = True
IF b = True Then
'deal with
Else
'deal with
END IF
End Sub
END CLASS
Select Case
The SELECT CASE statement is executed by branch judgment of multiple results of the condition. It is worth noting that the judgment expression of Seleect Case must be calculated as a basic data type (Boolean, Byte, CHAR, DATE, DOUBLE, DECIMAL, INTEGER, LONG, OBJECT, SHORT, SINGLE, and STRING).
VB.NET's CASE block execution cannot be "through" to the next Switch section. This is called "no running" rules. So there is no need to have Break to jump out of the CASE block.
The CASE sentence can be a single variable or a hybrid expression of TO and IS.
SELECT CSAE Example
Public Class Testa
Public Sub New ()
DIM I as INT32 = 100
SELECT CASE I
Case 1, 3, 5, 7
'deal with
Case 8 TO 12
'deal with
Case 13 to 21, 25
'deal with
Case 31 To 35, 39, IS> 50
'deal with
End SELECT
End Sub
END CLASS
