C# Pattern for aggregating interface methods into one generic method

I'm searching for a pattern to aggregating interface methods into one generic method.

Better to make an example of what I'm trying to do

Consider that I have an interface with 20 methods

interface MultiMethod{
   public TypeA A (p1,p2);
   public TypeA B (p1);
   public TypeC C (p5,p3,p2);
   .
   .
   .
}

Implementation Class

class MultiMethodeService : MultiMethod

In the MultiMethodeService I need to Implement all Interface methods, but the implementation of the methods is not real different.

Like:

public TypeA A (p1,p2){
   proxy.call("remoteA").params(p1,p2);
}
public TypeB B (p1){
   proxy.call("remoteB").params(p1);
}

I want to replace the implementation of the methods with one generic method that uses reflection.

The generic method derives

• the parameters form the MultiMethod interface the method name from


• the MultiMethode interface to invoke a proxy call

But how is it possible, when I have a generic method to also have the equal semantic like without a generic implementation. When I afterwords want to use the service object of MultiMethodService like :

var service = new MultiMethodService()
service.A(p1,p2)

Some naive idea was to implement an enum{"A","B"}

service.callGeneric(enum.A, p1,p2);
service.callGeneric(enum.B, p1); 

which is not really nice.

If you could provide any pattern or idea, your help is highly appreciated.
