WebClient.UploadFileCompleted Event

Definition

Si verifica al completamento di un'operazione asincrona di upload di file.Occurs when an asynchronous file-upload operation completes.

public:
 event System::Net::UploadFileCompletedEventHandler ^ UploadFileCompleted;
public event System.Net.UploadFileCompletedEventHandler UploadFileCompleted;

Public Custom Event UploadFileCompleted As UploadFileCompletedEventHandler 
Public Event UploadFileCompleted As UploadFileCompletedEventHandler 

Examples

Nell'esempio di codice riportato di seguito viene illustrata l'impostazione di un gestore eventi per questo evento.The following code example demonstrates setting an event handler for this event.

// Sample call: UploadFileInBackground2("http://www.contoso.com/fileUpload.aspx", "data.txt")
void UploadFileInBackground2( String^ address, String^ fileName )
{
   WebClient^ client = gcnew WebClient;
   Uri ^uri = gcnew Uri(address);

   client->UploadFileCompleted += 
     gcnew UploadFileCompletedEventHandler (UploadFileCallback2);
   
   // Specify a progress notification handler.
   client->UploadProgressChanged += 
       gcnew UploadProgressChangedEventHandler( UploadProgressCallback );
   client->UploadFileAsync( uri, "POST", fileName );
   Console::WriteLine( "File upload started." );
}


// Sample call: UploadFileInBackground2("http://www.contoso.com/fileUpload.aspx", "data.txt")
public static void UploadFileInBackground2 (string address, string fileName)
{
    WebClient client = new WebClient ();
    Uri uri = new Uri(address);

    client.UploadFileCompleted += new UploadFileCompletedEventHandler (UploadFileCallback2);

 // Specify a progress notification handler.
 client.UploadProgressChanged += new UploadProgressChangedEventHandler(UploadProgressCallback);
    client.UploadFileAsync (uri, "POST", fileName);
    Console.WriteLine ("File upload started.");
}

'  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

Remarks

Questo evento viene generato ogni volta che viene completata un'operazione di caricamento asincrona del file.This event is raised each time an asynchronous file upload operation completes. I caricamenti di file asincroni vengono avviati chiamando i metodi UploadFileAsync.Asynchronous file uploads are started by calling the UploadFileAsync methods.

Il UploadFileCompletedEventHandler è il delegato per questo evento.The UploadFileCompletedEventHandler is the delegate for this event. La classe UploadFileCompletedEventArgs fornisce il gestore eventi con i dati dell'evento.The UploadFileCompletedEventArgs class provides the event handler with event data.
