TcpClient.EndConnect Method

Note: This method is new in the .NET Framework version 2.0.

Asynchronously accepts an incoming connection attempt.

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

public void EndConnect (
	IAsyncResult asyncResult
)
public void EndConnect (
	IAsyncResult asyncResult
)
public function EndConnect (
	asyncResult : IAsyncResult
)

Parameters

asyncResult

An IAsyncResult object returned by a call to BeginConnect.

Exception typeCondition

ArgumentNullException

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

ArgumentException

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

InvalidOperationException

The EndConnect method was previously called for the asynchronous connection.

SocketException

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

ObjectDisposedException

The underlying Socket has been closed.

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

NoteNote

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.

public static ManualResetEvent connectDone = 
    new ManualResetEvent(false);

public static void ConnectCallback(IAsyncResult ar)
{
    connectDone.Set();
    TcpClient t = (TcpClient)ar.AsyncState;
    t.EndConnect(ar);
}
