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)
The Overlapped type exposes the following members.
| Name | Description | |
|---|---|---|
![]() ![]() ![]() | 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. |
| Name | Description | |
|---|---|---|
![]() ![]() ![]() | 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.) |
Note: |

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.
