What does this profiling result mean?

I opened a project (Visual C# - Windows Forms) and profiled it, and got the "hottest" methods. Now I can't understand the results because the hottest method is "collapsed methods without source". How ca开发者_JAVA百科n i understand what to fix if I can't see the method? What should i do?

Here is a pic so you can understand.

If you read the screen carefully, you'll notice the following:

Collapsed methods without source. To view these methods, change the display option to show all methods.

So, try changing the display option to show all methods. That should fix your problem.

Once you know the methods, you'll need to go find them in your source code.
