使用案例更改背景颜色| Visual Studio 2008

Question

我真的需要处理案例的帮助，目前为止我只是在学习它，但却无法获得可以改变文本框背景的下拉菜单。

Private Sub cbColours_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cbColours.SelectedIndexChanged 
    Select Case colours 

     Case Is = "Red" 
      txtSpace.BackColor = Color.Red 

     Case Is = "Blue" 
      txtSpace.BackColor = Color.Blue 

     Case Is = "Green" 
      txtSpace.BackColor = Color.Green 

    End Select 
End Sub 

它没有做任何事情...

在下拉菜单中，它具有

红，蓝，每行

绿色的

当值（例如绿色），然后将文本框更改为所选颜色。

很多帮助表示赞赏:)

不知道你在哪里得到的颜色值，这里的简单：

Private Sub cbColours_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cbColours.SelectedIndexChanged 
    Select Case Sender.Text  
     Case Is = "Red" 
      txtSpace.BackColor = Color.Red 

     Case Is = "Blue" 
      txtSpace.BackColor = Color.Blue 

     Case Is = "Green" 
      txtSpace.BackColor = Color.Green 

    End Select 
End Sub
