Ends a pending asynchronous disconnect request.
public:
void EndDisconnect(IAsyncResult ^ asyncResult);public void EndDisconnect (IAsyncResult asyncResult);member this.EndDisconnect : IAsyncResult -> unitPublic Sub EndDisconnect (asyncResult As IAsyncResult)Parameters
- asyncResult
- IAsyncResult
An IAsyncResult object that stores state information and any user-defined data for this asynchronous operation.
Exceptions
.NET Framework, .NET Core, and .NET 5-6 only: The Socket has been closed.
asyncResult is null.
asyncResult was not returned by a call to the BeginDisconnect(Boolean, AsyncCallback, Object) method.
EndDisconnect(IAsyncResult) was previously called for the asynchronous connection.
An error occurred when attempting to access the socket.
-or-
.NET 7+ only: The Socket has been closed.
The disconnect request has timed out.
Remarks
Important
This is a compatibility API. We don't recommend using the APM (Begin* and End*) methods for new development. Instead, use the Task-based equivalents.
EndDisconnect completes the operation started by BeginDisconnect. You need to pass the IAsyncResult created by the matching BeginDisconnect call. EndDisconnect will block the calling thread until the operation is completed.
Note
If you receive a SocketException, use the SocketException.ErrorCode property to obtain the specific error code.
Note
This member outputs trace information when you enable network tracing in your application. For more information, see Network Tracing in .NET Framework.
