vb .net,select语句,默认

Question

在CI中可以分配default给某些现有switch条目:

switch(c) {

default :
case 1:

       break;

case 2 :


      break;   

}

VB的select语句中是否存在类似的可能性？

Answer 1

使用case Else,它与c语法的默认值相同:

Select [ Case ] testexpression
    [ Case expressionlist
        [ statements ] ]
    [ Case Else
        [ elsestatements ] ]
End Select

例如

creamcake = TextBox1.Text

Select Case creamcake

Case "Eaten"
DietState = "Diet Ruined"
Case "Not Eaten"
DietState = "Diet Not Ruined"
Case Else
DietState = "Didn't check"
End Select

如果你想分配多个案例,那么例子

Select Case agerange

Case 16 To 21
MsgBox “Still Young”
Case 50 To 64
MsgBox “Start Lying”

End Select
