VB.NET: Can I programatically refer to the name of a class?

You can get the full type name as string from any object in .NET:

obj.GetType().ToString()

You could also pass in the actual object, rather than a string, and use TypeOf to determine the type:

Public Sub SomeMethod(ByVal sender As System.Object)

  If TypeOf (sender) Is Class1 Then

   MsgBox(sender.GetType().ToString())

  End If

End Sub

It's questionable if this is a good design though. You usually want classes to be as independent of each other as possible. If class A needs to know about class B and C to work, then you won't be able to use A from class D without changing A as well. Try to find a way to make your classes not so dependent on each other.

Vb.net Gettype

I don't really know much about Vb net but you could create a new variable for each class where for example in the first class this variable will have value of 1, the second one 2, third 3 etc

so basically by checking the value of the variable you can know which class called the method

Yes.

You can retrieve the name of the current class by using Me.GetType().Name. This will return the name of the class in a string that you can pass to your other method.

Check the article below for info on what you're really trying to do.

Only Suker is worth mentioning. Yes, there is Eduardo of Arsenal but he hasn't proven himself completely internationally. Obviously other members used wikipedia for fuller answers!

If you must know the name of the object that called the method then make that a parameter that gets passed in with the call to the method.

My $0.02 worth.

Why do you want to do that? Doing stuff like this kind of defeats the purpose of object-oriented programming.

No offense, but there's almost certainly a better way to accomplish this.
