How To Differentiate Different Components (Namespace) in Same Assembly in Profiler

Question

Hi,
I am trying to make a custom profiler that gives me information about method call sequence only when i try to call a method of different namespace from current namespace...
Example,
namespace sample
{
    class abc
    {
         public static void Main(String[] args)
         {
              double x = System.Math.Sin(1.5);
              xyz.print(x);
         }
    }
    public class xyz
    {
        public static void print(double x)
        {
               System.Console.WriteLine(x.ToString());
        }
    }
}

So, in above example when i try to call to method of System.Math (other than sample namespace) then i want information about method enter/exit but if my method call is of diiferent class but same namespace as in case of xyz.print method then i dont want information


So, i want to make a profiler that gives me information about all method calls belonging to another namespace..............
Is there any ID that differentiate two namespace as ObjectID and ThreadID that differentiate different class and threads????


Thanks in Advance................

Answer 1

Threads don't belong to any namespace, only types do (ClassID).

You can go through method's IL code, check all calls and ask for the callee method's type name (I guess you would have to use MetaData API). This might be tricky for virtual calls - as the call could be 'callvirt System.ToString()', but end up in Sample.abc.ToString(), when called on Sample.abc instance or instance of inheritted type.

You can get the type from ObjectID (ICorProfilerInfo::GetClassFromObject).

Pratik, if you don't think that my answer is sufficient, please give us more information why.
