Converting int to a string

Question

Hi I have no idea why am getting this kind of error Input was not in the correct format here is my line of codding... int userid = int.Parse(i.SubItems[3].Text);

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?

Enos · Answer

got this error Error 1 'System.Windows.Forms.ListViewItem' does not contain a definition for 'Substring' and no extension method 'Substring' accepting a first argument of type 'System.Windows.Forms.ListViewItem' could be found (are you missing a using directive or an assembly reference?)
