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

'Declaration <ComVisibleAttribute(True)> _ Public Class Overlapped
[ComVisibleAttribute(true)] public class Overlapped
The Overlapped type exposes the following members.
|Overlapped||Initializes a new, empty instance of the Overlapped class.|
|AsyncResult||Gets or sets the object that provides status information on the I/O operation.|
|OffsetHigh||Gets or sets the high-order word of the file position at which to start the transfer. The file position is a byte offset from the start of the file.|
|OffsetLow||Gets or sets the low-order word of the file position at which to start the transfer. The file position is a byte offset from the start of the file.|
|Equals(Object)||Determines whether the specified Object is equal to the current Object. (Inherited from Object.)|
|Finalize||Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)|
|GetHashCode||Serves as a hash function for a particular type. (Inherited from Object.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
This type is used by the .NET Framework for Silverlight. It cannot be used in Silverlight-based applications.
The Pack method transfers 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.
