I am building a basic profiler for an open source project. One requirement is to measure execution time of a method. While this is easy enough, I have to do it without knowing the method or its containing class until runtime. The way to invoke the profiler will be when the user will invoke the profiler from the IDE in an active document....

I.E. it would figure out the field names and values and send them out to a String...
I have been looking at Reflection.Emit recently. I wrote a simple program that generates a DynamicMethod which simple calls another method with the same parameters class Program { static void Main(string[] args) { Program p = new Program(); p.Test(); } public delegate void TestHandler(int a, int b, int c...
