WebClient.OnUploadFileCompleted Method

Raises the UploadFileCompleted event.

Namespace:  System.Net
Assembly:  System (in System.dll)
protected virtual void OnUploadFileCompleted(
	UploadFileCompletedEventArgs e
)

Parameters

e
Type: System.Net.UploadFileCompletedEventArgs

An UploadFileCompletedEventArgs object containing event data.

Classes that inherit from this class can override this method to perform additional tasks when the UploadFileCompleted event occurs.

Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.

The OnUploadFileCompleted method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

Notes to Inheritors:

When overriding OnUploadFileCompleted in a derived class, be sure to call the base class’s OnUploadFileCompleted method so that registered delegates receive the event.

The following code example shows an implementation of this method that can be customized by a class derived from WebClient.

protected override void OnUploadFileCompleted (UploadFileCompletedEventArgs e)
{
    // Here you can perform any custom actions before the event is raised 
    // and event handlers are called... 

    base.OnUploadFileCompleted (e);

    // Here you can perform any post event actions...
}
protected:
    void OnUploadFileCompleted (UploadFileCompletedEventArgs* e)
    {
        // Here you can perform any custom actions before the event is raised
        // and event handlers are called...

        WebClient::OnUploadFileCompleted (e);

        // Here you can perform any post event actions...
    }
