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 {
	void add(OpenWriteCompletedEventHandler^ value);
	void remove(OpenWriteCompletedEventHandler^ value);
}

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 NIB: Consuming Events.

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

void OpenResourceForWriting2( String^ address )
{
   WebClient^ client = gcnew WebClient;
   Uri ^uri = gcnew Uri(address);

   // Specify that the OpenWriteCallback method gets called
   // when the writeable stream is available.
   client->OpenWriteCompleted += gcnew OpenWriteCompletedEventHandler( OpenWriteCallback2 );
   client->OpenWriteAsync( uri, "POST" );

   // Applications can perform other tasks
   // while waiting for the upload to complete.
}
