How to get address of an object in C#

Question

How can I get address of an object in c#?

i searched and found

GCHandle handle = GCHandle.Alloc(obj, GCHandleType.WeakTrackResurrection);

int address = GCHandle.ToIntPtr(handle).ToInt32();

But need some more simple code

Is & operator can used here?

I know I'll regret asking, but why do you need the address of a C# object? — Mitch Wheat, Sep 14 '11 at 10:25
The real question is what do you plan to do with the address of an object in C# ? — Roee Gavirel, Sep 14 '11 at 10:25
Getting the address of an arbitrary object in .NET is not possible, but can be done if you change the source code and use mono. See instructions here: http://stackoverflow.com/questions/25410158/get-memory-address-of-net-object-c/25432952#25432952 — evolvedmicrobe, Aug 21 '14 at 18:00

Objects by default don't have a fixed address in C#, you'll need to explicitly tell the garbage collector to pin it.

Unsafe code. Compile with /unsafe (checkbox in the VS project properties)

unsafe
{
    fixed(MyobjType* objptr = &myobj)
    {
      // do sthng
    }
}

This generates error like: Cannot take the address of, get the size of, or declare a pointer to a managed type ('object') – Peteter Nov 12 '13 at 10:08
@Peteter Only works with structs. see http://msdn.microsoft.com/en-us/library/75dwhxf7.aspx – Olivier Nov 12 '13 at 10:17
