Using 'sender' in switch statement

[owdcoder83]

Is there any way in which an attribute of 'sender' in an event can be used in a 'switch' header'.
I find that I can use 'sender' like this :- if (sender == Pentagon) OK but if I try to use 'sender' like this I get an error :- ' switch (sender)'. What I am wanting to do is something like this :-

private void ShapeMenu_Click(object sender, EventArgs e)
{
switch (sender)
case Pentagon:
break;
case Hexagon:
break
}
