WebClient.OpenWriteCompleted Event

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

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

public event OpenWriteCompletedEventHandler OpenWriteCompleted
/** @event */
public void add_OpenWriteCompleted (OpenWriteCompletedEventHandler value)

/** @event */
public void remove_OpenWriteCompleted (OpenWriteCompletedEventHandler value)

In JScript, you can handle the events defined by a class, but you cannot define your own.
Not applicable.

This event is raised each time an asynchronous operation to open a stream that is used to send data to a resource completes. These operations are started by calling the OpenWriteAsync methods.

The OpenWriteCompletedEventHandler is the delegate for this event. The OpenWriteCompletedEventArgs 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 OpenResourceForWriting2 (string address)
{
    WebClient client = new WebClient ();
    Uri uri = new Uri(address);

    // Specify that the OpenWriteCallback method gets called
    // when the writeable stream is available.
    client.OpenWriteCompleted += new OpenWriteCompletedEventHandler (OpenWriteCallback2);
    client.OpenWriteAsync (uri, "POST");
    // Applications can perform other tasks
    // while waiting for the upload to complete.
}
