Need Method Entry and Exit event in .net

Question

Hi,

I like to have event like OnMethodEntry and OnMethodExit which will be used to raise an event when a method in a class is getting invoked in C#.NET.

I have seen Post Sharp which give this feature. Since it is third party tool, we like to design a library something similar to that.

How can I do that?

Thanks, P.Gopalakrishnan.

Answer 1

One way to do this is to modify assemblies by inserting these method calls manually in the IL.

Answer 2

CodeProject has a nice article that I think will meet your needs: MethodLogger - Hook into method calls in .NET binaries.

Answer 3

You may try Cecil or CCI. They are good and mature libraries for reading and patching assemblies.
