Occurs when an asynchronous string-upload operation completes.

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

public event System.Net.UploadStringCompletedEventHandler? UploadStringCompleted;

public event System.Net.UploadStringCompletedEventHandler UploadStringCompleted;

member this.UploadStringCompleted : System.Net.UploadStringCompletedEventHandler

Public Custom Event UploadStringCompleted As UploadStringCompletedEventHandler

Public Event UploadStringCompleted As UploadStringCompletedEventHandler

Event Type

UploadStringCompletedEventHandler

Examples

The following code example demonstrates setting an event handler for this event.

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

The following code example shows an implementation of a handler for this event.

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

Remarks

Oprez

WebRequest, HttpWebRequest, ServicePoint, and WebClient are obsolete, and you shouldn't use them for new development. Use HttpClient instead.

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

The UploadStringCompletedEventHandler is the delegate for this event. The UploadStringCompletedEventArgs class provides the event handler with event data.

For more information about how to handle events, see Handling and Raising Events.
