Getting method arguments inside a method

Is there a way to get method arguments inside a method body as an array of objects?

For example:

public void main()
{
   dosomething(2, "a");
}

public void dosomething(int a, string b)
{
     // get 2, "a" as object[] here
}

EDIT:
Some ascii art to explain the context.

--------                              --------
|client|     --- serialize call -->   |server|
--------                              --------
dosomething(2,"a");   --->            dosomething(2,"a");

Create a proxy on the client which will send the method name and args to the server and return it's value to the client.
