How C # Tests code run time

The first way:

System.Diagnostics.Stopwatch Stopwatch =NewStopwatch (); Stopwatch. Start ();//Start monitoring code run time// code to test .... Stopwatch. Stop (); // stop monitoring TimeSpan timespan = stopwatch. Elapsed; // Get the total time measured by the current instance  Double hours = TimeSpan. TotalHours; // total hours double minutes = TimeSpan. Totalminutes; // Total minutes double seconds = TimeSpan. TotalSeconds; // total seconds double milliseconds = TimeSpan. TotalMilliseconds; // Total number of milliseconds        

The second way:

New System.Diagnostics.Stopwatch (); watch. Start ();  // Start monitoring Code run time//////  Get the total time measured by the current instance
