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

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.

void OpenResourceForReading2( String^ address )
{
   WebClient^ client = gcnew WebClient;
   Uri ^uri = gcnew Uri(address);

   client->OpenReadCompleted += gcnew OpenReadCompletedEventHandler( OpenReadCallback2 );
   client->OpenReadAsync( uri );
}
void OpenResourceForReading2 (String* address)
{
    WebClient* client = new WebClient ();
    client->OpenReadCompleted += new OpenReadCompletedEventHandler (OpenReadCallback2);
    client->OpenReadAsync (address);
}
