选择案例类型可以控制吗？ [英] Select Case TypeOf Control Possible?

问题描述

亲爱的朋友，



我正在尝试编写如下代码 -

Dear Friend,

I am trying to write code as the following-

For Each ControlObject As Control In Me.Controls
    Select Case TypeOf ControlObject

         Case TextBox

         Case ComboBox

         Case Label

    End Select
Next

但它表示预计在第二行之后。是否有任何技术可以做到这一点？



问候

SKPaul

But it says that "Is expected" after the second line. Is there any technique to do it?

Regards
SKPaul

推荐答案

您应该使用如果Else 这样的声明

You should use If Else statement like this

If TypeOf ControlObject Is TextBox Then
ElseIf TypeOf ControlObject Is Button Then
End If

如果你想使用 Select Case 那么你可以这样做

If you want to use Select Case then you can do this as

Select Case True
        Case TypeOf ControlObject Is TextBox
        Case TypeOf ControlObject Is Button
End Select

我看，这是一个老帖子:)

如果有人正在寻找它，在我的情况下：

I see, this is an old post :)
If someone is looking for it, in my case:

Select Case val.GetType
			Case GetType(<yourType>)

		End Select

为我工作：）

worked for me :)
