c# - Is there a way to get an array of the arguments passed to a method?

Question

Say I have a method:

 public void SomeMethod(String p1, String p2, int p3)
 {

 #if DEBUG
    object[] args = GetArguments();
    LogParamaters(args);
 #endif

     // Do Normal stuff in the method
 }

Is there a way to retrieve an array of the arguments passed into the method, so that they can be logged?

I have a large number of methods and want to avoid manually passing the arguments by name to the logger, as human error will inevitably creep in.

I'm guessing it will involve reflection in some form - which is fine, as it will only be used for debugging purposes.

Update

A little more information:

I can't change the method signature of SomeMethod, as it is exposed as a WebMethod and has to replicate the legacy system it is impersonating.

The legacy system already logs the arguments that are passed in. To start with the new implementation will wrap the legacy system, so I'm looking to log the parameters coming into the C# version, so that I can verify the right parameters are passed in in the right order.

I'm just looking to log the argument values and order, not their names.

If you use Postsharp you can simply add an attribute to the method you want to log. Within this attribute you can write the logging code and also will provide the arguments you need. This is known as cross cutting concerns and AOP (Aspect orientated programming)
