Know how to find out how many milliseconds the MakeSome method takes and write the value to label1. thanks

Answer 1

Use the Stopwatch class from the System.Diagnostics namespace.

Answer 2

You can use the Stopwatch class:

 Stopwatch st = new Stopwatch(); st.Start(); // call MakeSome method... st.Stop(); 

Then you can check the st.ElapsedMilliseconds property.

Answer 3

Create a temporary variable and assign DateTime.Now, then subtract twice.

(Use a stopwatch class instead - it's more elegant)
