# Debugger Visualizers for MethodInfo, DynamicMethod, and MethodBase

By Roy Osherove November 2, 2007

**Historical article** · Originally published November 2, 2007; technical details may be outdated.

[Oren's post](http://www.ayende.com/Blog/archive/2007/10/29/Dynamic-Methods.aspx) about [DynamicMethods](http://msdn2.microsoft.com/en-us/library/system.reflection.emit.dynamicmethod.aspx) in Reflection is a great "advanced" intro to the idea of DyamicMethod (a method you can create on the fly and then cache to execute many times - great of optimization scenarios over multiple objects).

My last talk at TechEd Europe this year will be about "Deep Reflection". It is a variant of a session I did at TechEd Israel and one of the topics I cover there is the use of DyanmicMethods.

One of the things that I also show there is how you may be able to create a DyamicMethod and MethodInfo Visualizer, that shows you the IL produced in the method as you create it. Very powerful if you want to debug code generated at runtime.

Here's a screenshot of the visualizer at work over a MethodInfo object. It will work just as well on a DynamicMethod object:

You can download the visualizers for these here:

- [DynamicMethod and MethodInfo visualizers](http://teamagile.com/Downloads/DmVis.zip) (VS 2005 and VS 2008 bin versions)
- [The original post](http://weblogs.asp.net/rosherove/archive/2006/04/25/MethodsVisualizer.aspx) that also has links to the source code

\* possible cool thing you can do: Use [RunSharp](http://www.codeproject.com/dotnet/runsharp.asp) when generating the IL inside a DynamicMethod. I'm not sure it's possible but I'll check and maybe present this.
