WebClient.UploadFileCompleted Evento

Definição

Ocorre quando uma operação assíncrona de upload de arquivo é concluída.

public:
 event System::Net::UploadFileCompletedEventHandler ^ UploadFileCompleted;
public event System.Net.UploadFileCompletedEventHandler? UploadFileCompleted;
public event System.Net.UploadFileCompletedEventHandler UploadFileCompleted;
member this.UploadFileCompleted : System.Net.UploadFileCompletedEventHandler 
Public Custom Event UploadFileCompleted As UploadFileCompletedEventHandler 
Public Event UploadFileCompleted As UploadFileCompletedEventHandler 

Tipo de evento

Exemplos

O exemplo de código a seguir demonstra a configuração de um manipulador de eventos para esse evento.

// 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

O exemplo de código a seguir mostra uma implementação de um manipulador para esse evento.

void UploadFileCallback2( Object^ /*sender*/, UploadFileCompletedEventArgs^ e )
{
   String^ reply = System::Text::Encoding::UTF8->GetString( e->Result );
   Console::WriteLine( reply );
}
private static void UploadFileCallback2(Object sender, UploadFileCompletedEventArgs e)
{
    string reply = System.Text.Encoding.UTF8.GetString(e.Result);
    Console.WriteLine(reply);
}
Private Shared Sub UploadFileCallback2(ByVal sender As Object, ByVal e As System.Net.UploadFileCompletedEventArgs)

    Dim reply As String = System.Text.Encoding.UTF8.GetString(e.Result)
    Console.WriteLine(reply)
End Sub

Comentários

Cuidado

WebRequest, HttpWebRequest, ServicePointe WebClient estão obsoletos e você não deve usá-los para um novo desenvolvimento. Em vez disso, use HttpClient.

Esse evento é gerado sempre que uma operação de upload de arquivo assíncrona é concluída. Os uploads de arquivos assíncronos são iniciados chamando os métodos UploadFileAsync.

O UploadFileCompletedEventHandler é o representante deste evento. A classe UploadFileCompletedEventArgs fornece ao manipulador de eventos dados de evento.

Para obter mais informações sobre como lidar com eventos, consulte manipulação e geração de eventos.
