If you're writing a tracing and logging component you may well want to pass the current method name to your logging component. Rather than hard code it (then forget to change it when you change the method name) you can use reflection and the MethodBase class to retrieve the name.

System.Reflection.MethodBase currentMethod = System.Reflection.MethodBase.GetCurrentMethod();
System.Diagnostics.Debug.WriteLine(currentMethod.Name);
System.Diagnostics.Debug.WriteLine(currentMethod.DeclaringType.Name);
System.Diagnostics.Debug.WriteLine(currentMethod.DeclaringType.Namespace);
