StackFrame.GetMethod().Name

问题

I'm using this helper to resolve the name of the method that is currently being executed for logging purposes.

    [MethodImpl(MethodImplOptions.NoInlining)]
    public static string GetCurrentMethod()
    {
        StackTrace st = new StackTrace();
        StackFrame sf = st.GetFrame(1);

        return sf.GetMethod().Name;
    }

This is the string that is returned <Frequency>b__46

" What does the b__46 mean? And is there a way to just retrieve the word "Frequency?"

This is calling the helper.

    return ProxyCallWrapper.Execute<bool, IBackendJob>((backend, header) =>
    {
        header.CorrelationID = CorrelationID;
        logger.LogInfo(string.Format("### BSL CALL from {0} by {1} : CorrelationID: {2}", this.ToString(), GetCurrentMethod() ,header.CorrelationID));
        return backend.AddJob(header, jobId);
    });

回答1:

The method is probably being called from a lambda expression. The C# compiler actually converts lambdas to hidden methods inside your class. These methods have special compiler-generated names, like the <Frequency>b__46 you're seeing. I think you'll find if you look at GetFrame(2) you'll see the name you expect. Your function could ignore lambdas by looping up the stack until it finds a valid method name (you can check the method descriptor's IsSpecialName property for that).

The compiler also generates hidden methods with special names for auto property getters and setters, event add/remove handlers, and some other cases (you won't encounter these since these auto-generated methods can't call your GetCurrentMethod()). But note also that manual property getters and setters have "special" names like get_PropertyName(), and you may see those if you have a property whose code calls GetCurrentMethod().

回答2:

<Frequency>b__46 is the name of the method that called GetCurrentMethod().

Since you are calling the method from a lambda, you have to accept that the name of the lambda is beyond your control.
