TcpClient.EndConnect Method

Ends a pending asynchronous connection attempt.

Namespace:  System.Net.Sockets
Assembly:  System (in System.dll)

member EndConnect : 
        asyncResult:IAsyncResult -> unit


Type: System.IAsyncResult

An IAsyncResult object returned by a call to BeginConnect.


The asyncResult parameter is a null reference (Nothing in Visual Basic).


The asyncResult parameter was not returned by a call to a BeginConnect method.


The EndConnect method was previously called for the asynchronous connection.


An error occurred when attempting to access the Socket. See the Remarks section for more information.


The underlying Socket has been closed.

This method blocks until the operation is complete. To perform this operation synchronously, use a Connect method.


If you receive a SocketException, use SocketException.ErrorCode to obtain the specific error code. After you have obtained this code, you can 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.

The following code example ends the asynchronous connection attempt.
