Begins an asynchronous request to disconnect from a remote endpoint.
Assembly: System (in System.dll)
[<HostProtectionAttribute(SecurityAction.LinkDemand, ExternalThreading = true)>] member BeginDisconnect : reuseSocket:bool * callback:AsyncCallback * state:Object -> IAsyncResult
- Type: System.Boolean
true if this socket can be reused after the connection is closed; otherwise, false.
- Type: System.Object
An object that contains state information for this request.
If you are using a connection-oriented protocol, you can call the method to request a disconnect from a remote endpoint. If reuseSocket is true, you can reuse the socket.
The method uses a separate thread to invoke the specified callback method. The EndDisconnect method blocks until the pending disconnect is complete. For additional information on writing callback methods, see Callback Sample.
If you receive a SocketException exception, use the SocketException.ErrorCode property to obtain the specific error code. After you have obtained this code, refer to the Windows Sockets version 2 API error code documentation in the MSDN library for a detailed description of the error.
This member outputs trace information when you enable network tracing in your application. For more information, see Network Tracing.
The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: ExternalThreading. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.
The following code example creates a socket for asynchronous communication and sends some data to a remote host. When the data has been sent, Shutdown is called to stop the send and receive activity. Then is called to begin a disconnect request. When the request completes, the Connected property is queried to test whether the socket is disconnected.
