Can you use .Contains(string) with a Select Case S

问题:

Is there anyway I can build a Select statement that uses the Contains function? Like this:

Select commentStr
    Case commentStr.Contains("10")
    Case commentStr.Contains("15")

回答1:

Select Case True
    Case commentStr.Contains("10")
        'foo
    Case commentStr.Contains("15")
        'bar
End Select

Note that with this construct, a maximum of one Case will be executed.

(Also note that your C# friends can't do this with switch, which requires constant expressions in the case clauses :))
