How to get the object from a MethodBase class instance

Question

I have a module (Fody.MethodTimer) that I can extend my classes with attributes. When my class'es method gets executed it, invokes a static method (in another class)

public  class CommandBase
{
    [Time]
    public bool test()
    {
        return true;
    }
}

public static class MethodTimeLogger
{
    public static void Log(MethodBase methodBase, long milliseconds)
    {
        //Do some logging here
    }
}

Basically, after the method is call of test is complete, the Log method gets executed. As you can see, it get a MethodBase argument and has all that is needed do decribe the method that invoked this method call.

my Question is, If it is possible to get the object that invoked the Log method Call, out of The .NET MethodBase class instance.

Are you asking how you can get the stacktrace (in your case the calling method) for the current method? Then this might help you: http://stackoverflow.com/questions/171970/how-can-i-find-the-method-that-called-the-current-method — MakePeaceGreatAgain, Feb 03 '16 at 13:40
No, I would like to do some update to the object that invoked the Log method. I'll explain more in the edit — user853710, Feb 03 '16 at 13:41
Stack trace will give you the _method_ in which the `Log` function was called, but not the _object_. — D Stanley, Feb 03 '16 at 13:42
On a static method there is no instance that the method is called on, otherwise you could use the `this`-pointer. — MakePeaceGreatAgain, Feb 03 '16 at 13:42
You could always tweak https://github.com/Fody/MethodTimer/blob/master/Fody/AsyncMethodProcessor.cs and make your own version that returned more data. — Scott Chamberlain, Feb 03 '16 at 16:13

No. MethodBase is extracted from a type, not an instance. You will need to pass the instance in as a parameter if you want to invoke methods on it.

Even if you could, how would you know what parameter values to use when calling the method?

This is why all built-in event handlers have an object sender parameter - so you know which object triggered the event.

the sender is exactly what I want – user853710 Feb 03 '16 at 13:43
So add a parameter from the sender - why is that not an option? – D Stanley Feb 03 '16 at 13:49
Fody is a methodVeawer. The code does not exist until Build time. It get "generated" in build time and out of my control – user853710 Feb 03 '16 at 13:50
