Convert type' int' to 'SystemEventArgs"

I have problem with the Converting type int to SystemEventArgs.

I don't know what happen but I use the following sentence allready in another program and it is working fine

the sentence  is as follow:

g= Convert.ToInt32( response.InnerVaraibles[0].Data.ToString());

Now i'm doing it in another program and it give me the error : Cannot implicitly convert type'int" to 'System.EventArgs'

What can be the problem?
