How to get address of an object in C#

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?

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

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

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

See http://geekswithblogs.net/robp/archive/2008/08/13/speedy-c-part-3-understanding-memory-references-pinned-objects-and.aspx for a detailed description.
