    Image links are intended for real *images*. You've taken a picture of *code*, which is much more easily included as *text*. Edit your question to put the code in directly, and also copy and paste the stack trace into the question, including the message from the exception. – Jon Skeet Jun 21 '13 at 14:43

  • When someone edits your question to improve it, don't edit it back! Paste your code, not a picture of it. –  Jun 21 '13 at 14:52

You're trying to replace "" with "" - this is illegal.

Remove .Replace("", "");
