Use of Stopwatch Class in C#

Using the following line a new stopwatch object will be created.

System.Diagnostics.Stopwatch myStopWatch = new System.Diagnostics.Stopwatch();

The "Start" method will start the stopwatch.

myStopWatch.Start();

The "Stop" method will stop the stopwatch.

myStopWatch.Stop();

To display the value of the stopwatch then use the code shown below.

/// <summary>
/// To get the value of Hours..
/// </summary>

myStopWatch.Elapsed.Hours.ToString();

/// <summary>
/// To get the value of Minutes..
/// </summary>

myStopWatch.Elapsed.Minutes.ToString();

/// <summary>
/// To get the value of Seconds..

/// </summary>

myStopWatch.Elapsed.Seconds.ToString();


/// <summary>
/// To get the value of Milliseconds..
/// </summary> 
MyStopWatch.Elapsed.Milliseconds.ToString();
