WebClient.UploadStringCompleted Evento

Definição

Namespace:

System.Net

Assembly:

System.Net.WebClient.dll

Origem:

WebClient.cs

Ocorre quando uma operação assíncrona de upload de cadeia de caracteres é concluída.

public:
 event System::Net::UploadStringCompletedEventHandler ^ UploadStringCompleted;

public event System.Net.UploadStringCompletedEventHandler? UploadStringCompleted;

member this.UploadStringCompleted : System.Net.UploadStringCompletedEventHandler 

Public Custom Event UploadStringCompleted As UploadStringCompletedEventHandler 

Tipo de evento

UploadStringCompletedEventHandler

Exemplos

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

void UploadStringInBackground2( String^ address )
{
   WebClient^ client = gcnew WebClient;
   Uri ^uri = gcnew Uri(address);
   String^ data = "Time = 12:00am temperature = 50";

   client->UploadStringCompleted += gcnew UploadStringCompletedEventHandler( UploadStringCallback2 );
   client->UploadStringAsync( uri, data );
}

public static void UploadStringInBackground2(string address)
{
    WebClient client = new WebClient();
    Uri uri = new Uri(address);
    string data = "Time = 12:00am temperature = 50";
    client.UploadStringCompleted += new UploadStringCompletedEventHandler(UploadStringCallback2);
    client.UploadStringAsync(uri, data);
}

Public Shared Sub UploadStringInBackground2(ByVal address As String)

    Dim client As WebClient = New WebClient()
    Dim data As String = "Time = 12:00am temperature = 50"
    AddHandler client.UploadStringCompleted, AddressOf UploadStringCallback2
                Dim uri as Uri = New Uri(address)
    client.UploadStringAsync(uri, data)
End Sub

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

void UploadStringCallback2( Object^ /*sender*/, UploadStringCompletedEventArgs^ e )
{
   String^ reply = dynamic_cast<String^>(e->Result);
   Console::WriteLine( reply );
}

private static void UploadStringCallback2(Object sender, UploadStringCompletedEventArgs e)
{
    string reply = (string)e.Result;
    Console.WriteLine(reply);
}

Private Shared Sub UploadStringCallback2(ByVal sender As Object, ByVal e As UploadStringCompletedEventArgs)
    Dim reply As String = CStr(e.Result)
    Console.WriteLine(reply)
End Sub

Comentários

Esse evento é gerado sempre que uma operação de upload de cadeia de caracteres assíncrona é concluída. Os uploads de cadeia de caracteres assíncrona são iniciados chamando os UploadStringAsync métodos .

O UploadStringCompletedEventHandler é o delegado para esse evento. A UploadStringCompletedEventArgs classe fornece ao manipulador de eventos dados de evento.
