Determine full name of an object at runtime.

Is there any way to determine the full name of an object at runtime? For example, if I have the following

Namespace MyNameSpac
Public Class MyClas
Protected MyObject As Object 'This could be any type
End Clas
End Namespac

then I want a function that would return the string, "RootNamespace.MyNameSpace.MyClass.MyObject" if I passed MyObject to the function, where RootNamespace is the root namespace for the project

Thanks for any help

This is not possible. If you pass a reference to a function, the function
can not know where the reference was stored. Even if you'd pass it ByRef,
the function won't know of which object and which class and namespace the
referenced variable is part of.

What's your intention? I'm sure we'll find a solution.

Having this feature would have allowed me to automate a part of my app, but implementing a work around is not difficult

Thanks again for your help

Hi Lance,

I agree with Armin's suggestion. When we pass an object, we will not know
what class the object belong to, we have to do it ourself.

For a workaroud, You may try to pass the TestABC object in the meantime, so
that we know that.

e.g.
[TestCls]
Public Class TestABC
Public tls As ArrayList
Public tls2 As ArrayList
Public Shared Function Hello() As String
Return "Hello World"
End Function
End Class

[Module1.vb]
Dim o As New TestCls.TestABC
o.tls2 = New ArrayList
Dim c As Object
c = o.tls2
Console.WriteLine(o.GetType().ToString)
For Each b As System.Reflection.FieldInfo In o.GetType().GetFields()
If Object.ReferenceEquals(c, b.GetValue(o)) Then
Console.WriteLine(b.Name)
End If
Next
Console.WriteLine(o.Hello)
