What is fastest: (int), Convert.ToInt32(x) or Int32.Parse(x)?

Question

Which of the following code is fastest/best practice for converting some object x?

int myInt = (int)x;

or

int myInt = Convert.T         


        

Answer 1

In the end, they all end up calling:

System.Number.ParseInt32(string s, NumberStyles style, NumberFormatInfo info);

So in summary, there will be no difference what so ever.

Have a look in .Net Reflector to see this.
