Tricky boxing question

[Chris Capel]

I want to do something along the lines of this:

class someclass {
static void Main() {
int i = 5;
int j = 3;
changevalue(ref i, j);
Console.WriteLine(i.ToString()); //I want this to output 3
}
//it's important that this parameter is an object, and not an int or
something
static void changevalue(ref object i, object j) {
i = j
}
}

I'd like this to work for any type, not just ints. Is there any way to
accomplish something like this?

Hi Chris
The best you can do, I believe, is to revise your program logic

Hi Subash,
I don't thing this is exactly what Chris wants to do. a and b are declared
as a references to object. I think Chris wants to have changevalue method
regardles of the type of variables. It is kind a silly to keep value types
in boxing state. At least it is error prone.

class Class1
{
static void Main()
{
// Declaration
object a, b;
// Integer stuff
a = 1;
b = 2;
changevalue(ref a, b);
Console.WriteLine(a.ToString()); //This will output 2

// string stuff
a = "string 1";
b = "string 2";
changevalue(ref a, b);
Console.WriteLine(a.ToString()); //This will output "string 2"
}

static void changevalue(ref object i, object j)
{
i = j;
}
}

Yeah, that sounds ok. It's not an earth-shaking matter.

Hi Chris,

will change oA, and not a. In other words, I don't know how to create an
object that references the original value type. That is the point. You can't. Unless you make *changevalue* method to be
changevalue (ref int a, int b);

or you have to return back the value to its original varable after

changing it.
int a = 1, b = 2
object oA = (object) a;
changevalue(oA, b);
a = (int)oA; //What about if it is not *int*
