Try this

var value = ((double)fsize / tsize) * 100;
var percentage = Convert.ToInt32(Math.Round(value, 0));

You could try something like this:

double value = ((double)fsize / (double)tsize) * 100.0;

if fsize is int and tsize is int then the division is also an int and 0 is the correct answer. You need to convert it to double to get the correct value back.
