VB.Net - 巢狀 Select Case 語句

可以選擇語句作為外部選擇語句語句序列的一部分。即使內部和外部選擇語句的大小寫常量包含相同的值，也不會出現衝突。

示例

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

編譯並執行以上程式碼時，會產生以下結果 −

This is part of outer case
This is part of inner case
Exact value of a is : 100
Exact value of b is : 200
