Input string was not in a correct format.
It's pretty clear. You are trying to convert some data into a datatype that is incorrect.

Based on the line you mention, this means that username is not of type Int64. Further, AFAIK, Environment.Username is of type String. Thus, when you try to convert it into Int64, you get an error. It's a string, not an integer.

Refer: MSDN: Environment.UserName Property [^]
