[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Raises the DownloadStringCompleted event.
Assembly: System.Net (in System.Net.dll)
'Declaration Protected Overridable Sub OnDownloadStringCompleted ( _ e As DownloadStringCompletedEventArgs _ )
Parameters
- e
- Type: System.Net.DownloadStringCompletedEventArgs
A DownloadStringCompletedEventArgs object containing event data.
Classes that inherit from this class can override this method to perform additional tasks when the DownloadStringCompleted event occurs.
Raising an event invokes the event handler through a delegate.
The OnDownloadStringCompleted 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 InheritorsWhen overriding OnDownloadStringCompleted in a derived class, be sure to call the base class’s OnDownloadStringCompleted method so that registered delegates receive the event.
