OpenReadCompletedEventArgs Class

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

Provides data for the OpenReadCompleted event.

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

public class OpenReadCompletedEventArgs : AsyncCompletedEventArgs
public class OpenReadCompletedEventArgs extends AsyncCompletedEventArgs
public class OpenReadCompletedEventArgs extends AsyncCompletedEventArgs

Instances of this class are passed to OpenReadCompletedEventHandler methods.

The following code example demonstrates downloading a resource for reading.

public static void OpenResourceForReading2 (string address)
{
    WebClient client = new WebClient ();
    Uri uri = new Uri(address);

    client.OpenReadCompleted += new OpenReadCompletedEventHandler(OpenReadCallback2);
    client.OpenReadAsync (uri);
}


The following method is called when the download completes.

public static void OpenReadCallback2 (Object sender, OpenReadCompletedEventArgs e)
{
    Stream reply = null;
    StreamReader s = null;

    try
    {
        reply = (Stream)e.Result;
        s = new StreamReader (reply);
        Console.WriteLine (s.ReadToEnd ());
    }
    finally
    {
        if (s != null)
        {
            s.Close ();
        }

        if (reply != null)
        {
            reply.Close ();
        }
    }
}
