Use value-type references with generic

clement

Dear C# experts,
Is there any way to parametrize generics with value type reference.
I want to do something like this :

myObject.ID = 1;
List myInts = new List();
myInts.add(ref myObject.ID);
myInts[0] = 2;
Assert.IsTrue(myObject.ID == 2);

Not really.

The nearest you can get (assuming MyObject is a reference type) is:

     myObject.ID = 1;
     List myInts = new List();
     myInts.Add(myObject);
     myInts[0].ID = 2;
     Assert.IsTrue(myObject.ID == 2); //true

Thank you for the answer.

It's a shame we don't get the same flexibility as in C with pointers (list of int*).
I find it especially annoying for immutable types like string in c# : it means we can't modify
string references through a list.
