WebClient.UploadFileCompleted Event

Occurs when an asynchronous file-upload operation completes.

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

'Declaration
Public Event UploadFileCompleted As UploadFileCompletedEventHandler
'Usage
Dim instance As WebClient 
Dim handler As UploadFileCompletedEventHandler 

AddHandler instance.UploadFileCompleted, handler

This event is raised each time an asynchronous file upload operation completes. Asynchronous file uploads are started by calling the UploadFileAsync methods.

The UploadFileCompletedEventHandler is the delegate for this event. The UploadFileCompletedEventArgs 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.

		'  Sample call: UploadFileInBackground2("http:' www.contoso.com/fileUpload.aspx", "data.txt") 
		Public Shared Sub UploadFileInBackground2(ByVal address As String, ByVal fileName As String)

			Dim client As WebClient = New WebClient()
                        Dim uri as Uri =  New Uri(address)
			AddHandler client.UploadFileCompleted, AddressOf UploadFileCallback2

			'  Specify a progress notification handler. 
			AddHandler client.UploadProgressChanged, AddressOf UploadProgressCallback
			client.UploadFileAsync(uri, "POST", fileName)
			Console.WriteLine("File upload started.")
		End Sub
// Sample call: UploadFileInBackground2("http://www.contoso.com/fileUpload.aspx", "data.txt")
void UploadFileInBackground2 (String* address, String* fileName)
{
    WebClient* client = new WebClient ();

    client->UploadFileCompleted += new UploadFileCompletedEventHandler (UploadFileCallback2);

    // Specify a progress notification handler.
    client->UploadProgressChanged += new UploadProgressEventHandler(UploadProgressCallback);
    client->UploadFileAsync (address, S"POST", fileName);
    Console::WriteLine (S"File upload started.");
}
