Reflection: Get Subclass Type [modified]

[KenBonny]

I have a situation with inheritance. In my base class I have a function GetName() which I want to supply the name of the class that calls the function. But how do I give the name of my current subclass and not the base class? This is my code so far.

Class Base
Public Function GetName() As String
' Bad code
'Return System.Reflection.MethodBase.GetCurrentMethod().ReflectedType.Name.ToLower()

' Good code
Dim type as Type = Me.GetType()
Return type.Name

End Function
End Class

Class Sub
Inherits Base

' Some unrelated code
End Class

' In program somewhere
Dim s as Sub
Console.PrintLine(s.GetName()) ' should print out Sub, but it prints Base

EDIT: I found the solution. about 30 minutes after this post, I found it. :( Adjusted the code.

Hope this helps;

Class Base
Public Function GetClassName() As String
Return System.Reflection.MethodBase.GetCurrentMethod().ReflectedType.Name.ToLower()
End Function
Public Function GetCallingMethodName() As String
Return New StackTrace().GetFrame(1).GetMethod().Name
End Function
Public Function GetMethodName() As String
Return New StackTrace().GetFrame(0).GetMethod().Name
End Function
End Class

Class SubClass ' "Sub" is a reserved word and hence not a good idea as a classname
Inherits Base

' Some unrelated code
End Class

Module Module1
Sub main()
Dim s As New SubClass
Console.WriteLine(s.GetClassName()) ' prints the classname
Console.WriteLine(s.GetCallingMethodName()) ' prints the methodname (main)
Console.WriteLine(s.GetMethodName()) ' prints the methodname that's currently executed
Console.ReadKey()
End Sub
End Module

if you want information about the caller, Environment.StackTrace may be useful. if you want information about the base class of some object, look at Object.GetType(). and then there is reflection. :)

The Reflection will give you the "Base" name. The StackTrace would give you the name of the calling Mehtod. I needed the name of the type of the subclass. I know Sub is not a valid name, but I was making a quick example program, my actual program is a lot more complex, but I just needed the type of the subclass.

Thanks mate, I needed the Object.GetType(), used Me.GetType() works too. Thanks for the help, both of you!
