Get Class Name with extension in C#?

I am trying to get class name with the exten开发者_开发问答sion (e.g. Employee.cs or Employee.aspx.cs) in my code. I was able to get the name of the class without the extension but does anybody know how can i also get extension of the class??

This is what i did to get class name:

var frame = new StackFrame(1);
string className = frame.GetMethod().ReflectedType.Name;

That is not possible with reflection. The name of the source compilation file is not part of the metadata of the type.

Call frame.GetFileName().
This will only work if you have the PDB file.
