Using reflection, how can I get the instances of objects that are passed into a function and then pass those instances to another function?

I was hoping for a single line solution that I can paste in every single function in my solution. I have a macro that I can use to insert a line of code in every function already
An example would be as follows:
functionone(param1, param2)
{
logmyparams(); //inserted line
}
functiontwo(param1, param2, param3)
{
logmyparams(); //inserted line
}
The only way I see to do this is to write your classes and functions to support this. The simplest example of this is to have every function have a signature like functionName(object[] params) then you could do logmyparams(params) in each method. logmyparams could then loop the array. This is of course not the most elegant of the possible examples of doing this kind of thing, but it gives you the idea.
Unfortunately as I mentioned in my other post reflection uses the static metadata information from the assembly, it doesn't interrogate the actual memory location of the object. .NET is very protective of the stack and the heap. So unlike something like c++ which would allow you to peek at the actual memory loctation of the parameter, but also allows you to do lots of things to blow up your app and even crash your whole computer; c#, etc prevents you from doing what you are trying to do, but also makes it a lot harder to hurt yourself badly.
I suppose what I'm going to have to do is modify the macro to insert as you suggested above, one line for every parameter. This will work, but it isn't as elegant as I was hoping for. It does save cycles since I wouldn't have to use reflection to get the parameters, but I'm betting it has to be possible. Thanks for your response James.

is there any reason you can't just do:
public void functionOne(string username, mycustomobject mycustobj)
{
objectLogger(username);
objectLogger(mycustobj);
}
