WebClient.OpenReadCompleted Event

Occurs when an asynchronous operation to open a stream containing a resource completes.

Namespace:  System.Net
Assembly:  System (in System.dll)
public event OpenReadCompletedEventHandler OpenReadCompleted

This event is raised each time an asynchronous operation to open a stream containing a resource completes. These operations are started by calling the OpenReadAsync methods.

The OpenReadCompletedEventHandler is the delegate for this event. The OpenReadCompletedEventArgs class provides the event handler with event data.

For more information about handling events, see Consuming Events.

The following code example demonstrates setting an event handler for this event.


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

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