Converting int to a string

It appears from the error message that the Text property of that particular ListViewItem doesn't contain something that can be parsed to an integer.

What in fact does it contain?

Incidentally, you can guard against errors of this type by using int.TryParse rather than int.Parse:

int userid;
int.TryParse(i.SubItems[3].Text, out userid);
// userid will contain 0 if the Text property contains something non-integral

Hi Enos,
can you describe what is i in your code?

got this error,
