Is it possible to do the following?

public SomeClass
{
private DiscoverClass discObj = new DiscoverClass( );

public void SomeMethod(string someparam1, int someparam2)
{
    int somelocalvar;
    SomeClass someobj = new SomeClass( );

    discObj.DoDiscovery();


}
}




public class DiscoveryClass
{
     public DiscoveryClass(){}

    public void DoDiscovery(  )
    {
         System.Diagnostics.Debug.WriteLine("Entered method <<SomeMethod>> which is inside class <<SomeClass>>");
    }
}

Open in new window




 <<SomeMethod>>
and
<<SomeClass>>


would be found using Reflection.



Possible?

I'm not quite following what you want but something like http://msdn.microsoft.com/en-us/library/system.reflection.typedelegator.aspx would help

Tom,

If you are just trying to get the information about the method, there is the System.Diagnostics.StackFrame class that should do the trick.

The joys of System.Diagnostics.StackFrame
http://mikehadlow.blogspot.com/2007/09/joys-of-systemdiagnosticsstackframe.html

StackFrame stackFrame = new StackFrame(1, false);
MethodBase method = stackFrame.GetMethod();
Console.WriteLine("The name of the method was: {0}", method.Name);

Open in new window


The constructor for the StackFrame has different overloads.  The example is using this constructor:

StackFrame Constructor (Int32, Boolean)
http://msdn.microsoft.com/en-us/library/deysbxxw.aspx

skipFrames
Type: System.Int32
The number of frames up the stack to skip.

fNeedFileInfo
Type: System.Boolean
true to capture the file name, line number, and column number of the stack frame; otherwise, false.

The stack is in reverse order, so 0 = current method, 1 = calling method, etc.  This is how you get the stack trace when exceptions occur.
