The error you got is pretty clear - You can not pass less than zero for an ZERO-BASED indexing scenarios.

And I think as no string ',' is found LastIndexOf is giving -1

Try checking this -1 return and handle accordingly.

Solution 2

int backSlashIndex = text.IndexOf("\\");
domain = (backSlashIndex >= 0) ? text.Substring(0, backSlashIndex) : text;
