You have to use either int.Parse[^] or int.TryParse[^]

int quan = 0;
quan = int.Parse(textbox.Text);

This puts the integer value into "quan" or throws an exception if there are problems with the conversion.

int quan = 0;
if (int.TryParse(textbox.Text, out quan))
   {
   ...
   }

This put the integer value into "quan" and returns true, or returns false if there are problems with the conversion.

int.Parse or int.TryParse will do the trick!
