Begins an asynchronous operation to accept an incoming connection attempt.
Assembly: System (in System.dll)
[<HostProtectionAttribute(SecurityAction.LinkDemand, ExternalThreading = true)>] member BeginAcceptTcpClient : callback:AsyncCallback * state:Object -> IAsyncResult
- Type: System.AsyncCallback
An AsyncCallback delegate that references the method to invoke when the operation is complete.
- Type: System.Object
A user-defined object containing information about the accept operation. This object is passed to the callback delegate when the operation is complete.
The asynchronous operation must be completed by calling the EndAcceptTcpClient method. Typically, the method is invoked by the callback delegate.
This method does not block until the operation completes. To block until the operation completes, use the AcceptTcpClient method.
For detailed information about using the asynchronous programming model, see Calling Synchronous Methods Asynchronously.
If you receive a SocketException, use the SocketException.ErrorCode property to obtain the specific error code and refer to the Windows Sockets version 2 API error code documentation in the MSDN library at http://msdn.microsoft.com/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 in the .NET Framework.
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.
