hey all,
is there another way to say the following (seems too wordy)

prefix == "TXT" || prefix == "DRP" || prefix == "LBL" || prefix == "CHK" ||
prefix == "UPD" || prefix == "UPC"

thanks,

switch (prefix)
{
case "TXT" :
case "DRP" :
case "LBL" :
case "CHK" :
case "UPD" :
case "UPC" :
{
// do something
break;
}
default :
{
// for any other case
break;
}
}

Also, remember that C# is case-sensitive, so if prefix is "txt", it will
fall through to the default section...

When did they change that then? I'm pretty sure that the C# team didn't
implement switch statement fall through.

I don't believe they ever have...

Have you tried it...?

Have to admit I've not tried recently but all the documentation indicates
that you still can't do case statement fall throughs - even in the article
that you link to it states:

Unlike the C++ switch statement, C# does not support an explicit fall
through from one case label to another. If you want, you can use goto a
switch-case, or goto default.

OK...

but all the documentation indicates that you still can't do case statement
fall throughs

Nevertheless...

I don't believe that it's any change.

You can't to a fall through from one case to another when it contains
code, but you can make a fall through when there is no code in the case.
