Use Stopwatch to measure the time taken to execute the code.

You can use the StopWatch class from the System.Diagnostics namespace to measure time taken to execute a certain block of code

Stopwatch myWatch = new Stopwatch();
myWatch.Start();

//your code

myWatch.Stop();
string timeTaken = string.Format(""{0} was taken to execute the code."", myWatch.ElapsedMilliseconds);
