The static methods defined on the Marshal class are essential to working with unmanaged code. Most methods defined in this class are typically used by developers who need to provide a bridge between the managed and unmanaged programming models. For example, the StringToHGlobalAnsi method copies ANSI characters from a specified string (in the managed heap) to a buffer in the unmanaged heap. It also allocates the target heap of the right size.
The common language runtime provides specific marshaling capabilities. For details on marshaling behavior, see Interop Marshaling.
