Returns a new GCHandle object created from a handle to a managed object.
Assemblies: System.Runtime.InteropServices (in System.Runtime.InteropServices.dll)
mscorlib (in mscorlib.dll)
The following code example shows an App class that creates a handle to a managed object using the GCHandle.Alloc method, which prevents the managed object from being collected. A call to the EnumWindows method passes a delegate and a managed object (both declared as managed types, but not shown), and casts the handle to an IntPtr object. The unmanaged function passes the type back to the caller as a parameter of the callback function.
