I have a delegate and it works fine, but I'm having difficulty using it w/ a
switch statement.

Basically, i have a component that has a listbox with a delegate for the
SelectedIndexChanged event. On the main form where i'm capturing the event
I want to use a switch statement to see what the user selected. The
"sender" has the value (based on the debugger) {SelectedItem="my value"}.
How do I capture this in a switch statement?

Click to expand...

ListBox list = sender as ListBox;
if (list != null) {
switch (list.SelectedItem.Text) {
case "Item 1":
//yada, yada, yada
}
}

Hi Doug,
It depends on what the type of the items in the list box is.
Don't forget that you can use only primitive types with *switch* statement.

So if you have strings as ListBox items you can do the following

switch(((ListBox)sender).SelectedItem.ToString())
{
case "string1":
break;
case "string2":
.....
}

Even if you have some non-primitive objects you can override ToString()
method and if you can produce some strings do distinguish the objects you
can use the same *switch* statement.

You always can use *if...else if...else* insted, though.
