Socket.DuplicateAndClose Method
Duplicates the socket reference for the target process, and closes the socket for this process.
Assembly: System (in System.dll)
Parameters
- targetProcessId
- Type: System.Int32
The ID of the target process where a duplicate of the socket reference is created.
Return Value
Type: System.Net.Sockets.SocketInformationThe socket reference to be passed to the target process.
| Exception | Condition |
|---|---|
| SocketException | targetProcessID is not a valid process id. -or- Duplication of the socket reference failed. |
The target process should use Socket to create the duplicate socket instance.
If you call the Socket constructor multiple times with the same byte array as the argument for each call, you will create multiple managed Sockets with the same underlying socket. This practice is strongly discouraged.
If the process creating the socket uses asynchronous methods (BeginReceive or BeginSend), the process must first set the UseOnlyOverlappedIO property to true; otherwise, the socket is bound to the completion port of the creating process, which may cause an ArgumentNullException to be thrown on the target process.
