Int32.Parse() VS Convert.ToInt32()?

Question

intID1 = Int32.Parse(myValue.ToString());
intID2 = Convert.ToInt32(myValue);

Which one is better and why?

Answer 1

They are exactly the same, except that Convert.ToInt32(null) returns 0.

Convert.ToInt32 is defined as follows:

    public static int ToInt32(String value) {
        if (value == null) 
            return 0;
        return Int32.Parse(value, CultureInfo.CurrentCulture);
    }
