Why does this produce “0” ?
object a = 0;
object b = a;
a = null;
Console.WriteLine(b.ToString()); // Produces "0"
Console.Read();
Doesn’t b point to the same location and setting a = null effectively makes b null?
A picture is worth a thousand words:
Setting
a = nullremovesa‘s reference (the arrow) to the object (the boxed integer0). It does not affect the object itself.bstill references the unchanged object afterwards.
