getting the name of the calling method

Question

Basically i've got a web service that i'm trying to put some kind of usage logging in. To do this i've created a class with a logging method. I instatiate the class on the service and then call the logging method in each of the web methods.

I'm trying to find a way of getting the name of the method that has called the loggong method

Public sub tstmethod
log_object.log_method
end sub

in this case the returned name i'm looking for is "tstmethod"

Everywhere i've seen has said to either use

Dim stackframe As New Diagnostics.StackFrame
Return stackframe.GetMethod.Name.ToString

Or to use

Dim stackframe As New Diagnostics.StackFrame
Return stackframe.GetMethod.DeclaringType.FullName

which i call inside the logging method

getmethod.name.tostring returns the name of the logging method

getmethod.declaringtype.fullname returns the name of the logging class

no matter what i do i cannot find a way of getting the name of the method that called the logging method in this case "tstmethod"

Answer 1

You need to instantiate the StackFrame with an appropriate constructor. For example,

Dim stackframe As New Diagnostics.StackFrame(1)

will skip one stack frame (the logging method itself) and get the frame for the caller of that method.

That said - if at all possible, I'd strongly recommend using a standard logging mechanism such as log4net.

Answer 2

I think the above statement can be made into one single line:

MsgBox((New System.Diagnostics.StackTrace).GetFrame(1).GetMethod.Name)

This will display a Message Box as with calling method name.
