Overlapped Class

Provides a managed representation of a Win32 OVERLAPPED structure, including methods to transfer information from an Overlapped instance to a NativeOverlapped structure.

Namespace: System.Threading
Assembly: mscorlib (in mscorlib.dll)

[ComVisibleAttribute(true)] 
public class Overlapped
/** @attribute ComVisibleAttribute(true) */ 
public class Overlapped

public class Overlapped

The Pack and UnsafePack methods transfer information from an Overlapped object to a NativeOverlapped structure that can be passed to Win32 API functions for asynchronous file I/O. The Unpack method transfers information from a NativeOverlapped structure to an instance of the Overlapped class.

Changes to the properties of an Overlapped object affect its associated NativeOverlapped structure, and vice versa.
