regular expressions - "this expression causes side effects and will not be be evaluated"

[joyce]

hi group,

When I was trying to do a match on
Regex.isMatch("$test",@"^\$")

this seems to return "this expression causes side effects and will not
be be evaluated", any ideas what I'm doing wrong?

thanks,
Joyce

Did you use the return value? As in

if (Regex.IsMatch(...)) ...

Do you mean that you saw this message in a Debug Window? Side effects in a
debugger can be caused by evaluating a method or function call.
