ASP.NET - How can I check how many milliseconds my codes takes to execute, using Visual Studio 2010

Is it possible to check how long a particular segment of code takes to execute, j开发者_StackOverflowust want to see if some loops etc. can be optimized better or use LinQ.

Is there such function built into Visual Studio or must I do this with some code, stopwatch class etc.?

Thanks.

var sw = Stopwatch.StartNew();

// you code.

sw.ElapsedMilliseconds;

Or you can use built in VS Profiler. You can find more on how to use VS profiler in Find Application Bottlenecks with Visual Studio Profiler

If you have VS2010 Ultimate:

From the Analyze menu, select the Launch Performance Wizard option.

Its been a while since I last used it, but I believe it tells you how long things take to execute and what's using up the most memory, and so on =)

Otherwise, you'll have to use the Stopwatch class or a third party profiler.

Visual Studio Premium/Ultimate/Team versions come with a profiler. Otherwise you have to do your own profiling with the StopWatch class.
