Is it possible to get the referring method in VB.NET?

Question

See this example:

''//file1.vb
Sub Something()
    ''//...
    Functions.LogInfo("some text")
    ''//...
End Sub

''//functions.vb
Sub LogInfo(ByVal entry as String)

    Console.WriteLine(entry)

End Sub

Can I get the the name "Something" inside LogInfo?

Sorry for the briefness of this post, I am not sure how to properly articulate this question. I will clarify and elaborate as needed.

Answer 1

(EDIT: Removed unnecessary use of StackTrace itself - which would be useful if you wanted to print out more info than just one frame.)

You can use the StackFrame class, but it's pretty expensive (IIRC) and may be slightly incorrect due to inlining.

EDIT: Something like this: (the NoInlining is to make sure it behaves properly...)

Imports System.Diagnostics
Imports System.Runtime.CompilerServices

Public Class Test

    Shared Sub Main()
        Something()
    End Sub        

    <MethodImpl(MethodImplOptions.NoInlining)> _
    Shared Sub Something()        
        Functions.LogInfo("some text")
    End Sub

End Class

Public Class Functions

    <MethodImpl(MethodImplOptions.NoInlining)> _
    Public Shared Sub LogInfo (ByVal entry as String)
        Dim frame as StackFrame = new StackFrame(1, False)
        Console.WriteLine("{0}: {1}", _
                          frame.GetMethod.Name, _
                          entry)
    End Sub

End Class

Answer 2

Take a look at How can I find the method that called the current method?.

Translated to VB (Hopefully):

Imports System.Diagnostics
''// get call stack
Dim stackTrace As New StackTrace()

''// get calling method name
Console.WriteLine(stackTrace.GetFrame(1).GetMethod().Name)

Answer 3

You can use the StackFrame or StackTrace. But your behavior might different in release builds vs running in the debugger due to inlining. So your results might be not what you expect:

c#:

System.Diagnostics.StackFrame sf = new StackFrame(1);
sf.GetMethod().Name;

vb:

Dim sf as new StackFrame(1)
sf.GetMethod().Name

Edit

Sorry just realized you asked for vb.net. I edited my response but the vb syntax might not be right

System.Reflection.MethodBase.GetCurrentMethod.Name does the same thing and is seemingly easier to get the hang of
