passing object reference to the method

[puzzlecracker]

Say I pass an object of a class (reference value I suppose) to a
method, and I want to pass it by reference. Do I need to preappend
it with ref.

public interface IFoo{}

public class Foo:IFoo{

}

void FromHere()
{

Foo f=new Foo();
Here(ref f);

}

void Here(ref IFoo f )
{
//do something with f
}

Is ref redundant or error-prone. In my scenerio I have a lot of
overload for Here-like function,
and compiler screams that it cannot convert IFoo to char (latter
beeing void Here(ref char c) )
Thanks
