StopWatch.cs | C# Timer Class by Corey Goldberg

StopWatch.cs | C# Timer Class

This creates an object like a stopwatch for wrapping blocks of code in timers.

Update:

• This was the class I wrote for .NET 1.x
• In .NET 2.0, a Stopwatch class was introduced in the System.Diagnostics namespace
• I still like this version and use it regularly with the most recent .NET
