Solution 1

Isn't this obvious? Of course, a starting index larger than the length could not possibly make sense.

Now, about fixing it… This is not in the code you show. Look for the call to String.Substring. However, the approach is wrong. Run it under debugger; it will show you exact point where the exception was thrown.

but i get this error, when i deploy this form. i don't understand why? can you tell more detail?

thx

Your error will have nothing to do with your deployment. Use your debugger (F5) and you will encounter the error. Visual Studio will then show you where the error has occured.

i didn't get error from my debbuger.it make me confused..:(

Check up all the debugger's settings under [Main Menu] -> Debug -> Exceptions. Something might be disabled.
