C# has no concept of a reference variable akin to C++'s int& a. There are workarounds. One is to use closures:

class Test
{
    private Func get_a;
    private Action set_a;
    public Test(Func get_a, Action set_a)
    {
        this.get_a = get_a;
        this.set_a = set_a;
        this.set_a(this.get_a() + 1);
    }
    public Object getA() { return this.get_a(); }
}
/*
 * ...
 */
static void Main(string[] args)
{
    int a;
    a=3;
    Test t = new Test(() => a, n => { a = n; });
    Console.WriteLine(a);
    Console.WriteLine(t.getA());
    Console.ReadKey();
}

I'm not in front of VS, so please excuse any embarrassing faux pas.
