NegotiateStream.EndWrite Method

Ends an asynchronous write operation that was started with a call to BeginWrite.

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

public override void EndWrite(
	IAsyncResult asyncResult
)

Parameters

asyncResult
Type: System.IAsyncResult

An IAsyncResult instance returned by a call to BeginWrite

ExceptionCondition
ArgumentNullException

asyncResult is null.

ArgumentException

The asyncResult was not created by a call to BeginWrite.

InvalidOperationException

There is no pending write operation to complete.

IOException

The write operation failed.

InvalidOperationException

Authentication has not occurred.

If the operation has not completed, this method blocks until it does.

You cannot call this method until you have successfully authenticated. To authenticate, call one of the AuthenticateAsClient, BeginAuthenticateAsClient, AuthenticateAsServer, or BeginAuthenticateAsServer methods.

To perform this operation synchronously, use the Write method.

The following code example demonstrates a method that is called to complete the asynchronous write operation. For an example that demonstrates starting the operation, see BeginWrite.

// The following method is called when the write operation completes. 
public static void EndWriteCallback (IAsyncResult ar)
{
    Console.WriteLine("Client ending write operation...");
    NegotiateStream authStream = (NegotiateStream) ar.AsyncState;

    // End the asynchronous operation.
    authStream.EndWrite(ar);
}
    // The following method is called when the write operation completes.
public:
    static void EndWriteCallback (IAsyncResult* ar)
    {
        Console::WriteLine(S"Client ending write operation...");
        NegotiateStream* authStream = dynamic_cast<NegotiateStream*> (ar->AsyncState);

        // End the asynchronous operation.
        authStream->EndWrite(ar);
    }
