Définition

Espace de noms:

System.Net

Assembly:

System.Net.WebClient.dll

Source:

WebClient.cs

Se produit lorsqu’une opération de chargement de chaîne asynchrone se termine.

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

public event System.Net.UploadStringCompletedEventHandler? UploadStringCompleted;

member this.UploadStringCompleted : System.Net.UploadStringCompletedEventHandler 

Public Custom Event UploadStringCompleted As UploadStringCompletedEventHandler 

Type d'événement

UploadStringCompletedEventHandler

Exemples

L’exemple de code suivant illustre la définition d’un gestionnaire d’événements pour cet événement.

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

L’exemple de code suivant montre une implémentation d’un gestionnaire pour cet événement.

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

Remarques

Prudence

WebRequest, HttpWebRequest, ServicePointet WebClient sont obsolètes et vous ne devez pas les utiliser pour le nouveau développement. Utilisez HttpClient à la place.

Cet événement est déclenché chaque fois qu’une opération de chargement de chaîne asynchrone se termine. Les chargements de chaîne asynchrones sont démarrés en appelant les méthodes UploadStringAsync.

Le UploadStringCompletedEventHandler est le délégué de cet événement. La classe UploadStringCompletedEventArgs fournit au gestionnaire d’événements des données d’événement.
