可以將select
語句作為外部select
語句的語句序列的一部分。即使內部和外部選擇的情況常數包含共同的值,也不會產生衝突。
Module decisions
Sub Main()
'local variable definition'
Dim a As Integer = 100
Dim b As Integer = 200
Select a
Case 100
Console.WriteLine("This is part of outer case ")
Select Case b
Case 200
Console.WriteLine("This is part of inner case ")
End Select
End Select
Console.WriteLine("Exact value of a is : {0}", a)
Console.WriteLine("Exact value of b is : {0}", b)
Console.ReadLine()
End Sub
End Module
執行上面範例程式碼,得到以下結果 -
This is part of outer case
This is part of inner case
Exact value of a is : 100
Exact value of b is : 200
