C# in a Nutshell

Name

Marshal

Synopsis

This class offers a collection of static methods for working with unmanaged memory and converting managed types to unmanaged types. Unless you are developing specialized code for marshaling types between managed and unmanaged code, you probably do not need to use any of these methods.

GetHRForException() converts a .NET exception to a COM HResult. If you are curious about the platform you are running on, you can find out the size of a character with the SystemDefaultCharSize field, which is 1 on an ANSI platform (Windows 9x/ME) and 2 on a Unicode platform (Windows NT, 2000, and XP).

Use the IsComObject() method to determine whether an object is actually an unmanaged COM object. The AddRef() method increments a COM object’s reference count.
