Here is what you wanted. :) System.Convert.ToInt32(string) is public static int ToInt32(string value) {     if (value == null)         return 0;     return Int32.Parse(value); } and System.Int32.Parse is public static int Parse(string s) {     return Int32.Parse(s, 7, null); } So we now know for sure that the Convert.ToInt32(string) calls Int32.Parse(value), so I would assume it is more efficient to use Int32.Parse instead of Convert.ToInt32().

I did 100,000 conversions with int.Parse(string) and Convert.ToInt32(string). Parse completed it in 9.183 seconds. Convert completed it in 9.283 seconds. Yes Parse is faster, but if a program is running slow, I'd suggest looking for the bottleneck somewhere else.
