如何根据checkedlistbox更改字符串

Question

非常自我解释。如果在checkedListBox中选中了某个选项，我想更改一个字符串。选中其他选项后再次更改。我会说if语句会起作用但是我如何在if语句中这样做，以便其他对象可以使用该字符串？

您可以使字符串成为常量，并在checkedListBox的SelectedIndexChanged事件中为其赋值。像（伪代码）的东西：

private readonly String clbResponse = String.Empty;
. . .
protected void clb_SelectedIndexChanged(object sender, eventargs e)
{
    int indexSelected = clb.SelectedIndex;
    case (indexSelected)
    0:
     clbResponse = "index 0 was selected";
     break;
    1: 
     clbResponse = "index 0 was selected";
     break;
    . . .
    default
       break;
}
