SslStream.EndWrite Method

Ends an asynchronous write operation started with a previous 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

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.

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

To perform this operation synchronously, use the Write method.

The following code example demonstrates ending an asynchronous write operation.


void WriteCallback(IAsyncResult ar)
{
    ClientState state = (ClientState) ar.AsyncState;
    SslStream stream = state.stream;
    try 
    {
        Console.WriteLine("Writing data to the client.");
        stream.EndWrite(ar);
    }
    catch (Exception writeException)
    {
        Console.WriteLine("Write error: {0}", 
            writeException.Message);
        state.Close();
        return;
    }
    Console.WriteLine("Finished with client.");
    state.Close();
}
