It seems to me C# ref variables are very much like C++ ref 
variables (tested and works ;on my machine):

using System.Diagnostics;

class C
{
     static void Main()
     {
         var i = 3;
         ref int ir = ref i;
         ir = 17;
         Debug.Assert(i == 17);
     }
}

Can't have const references to literal values (e.g. const int& i 
= 13;) like in C++, though.
