Definisi

Menyediakan data untuk peristiwa tersebut UploadDataCompleted .

public ref class UploadDataCompletedEventArgs : System::ComponentModel::AsyncCompletedEventArgs
public class UploadDataCompletedEventArgs : System.ComponentModel.AsyncCompletedEventArgs
type UploadDataCompletedEventArgs = class
    inherit AsyncCompletedEventArgs
Public Class UploadDataCompletedEventArgs
Inherits AsyncCompletedEventArgs
Warisan
UploadDataCompletedEventArgs

Contoh

Contoh kode berikut menunjukkan pengunggahan data secara asinkron.

void UploadDataInBackground2( String^ address )
{
   WebClient^ client = gcnew WebClient;
   Uri ^uri = gcnew Uri(address);
   String^ text = "Time = 12:00am temperature = 50";
   array<Byte>^data = System::Text::Encoding::UTF8->GetBytes( text );
   String^ method = "POST";

   client->UploadDataCompleted += gcnew UploadDataCompletedEventHandler( UploadDataCallback2 );
   client->UploadDataAsync( uri, method, data );
}
public static void UploadDataInBackground2(string address)
{
    WebClient client = new WebClient();
    Uri uri = new Uri(address);
    string text = "Time = 12:00am temperature = 50";
    byte[] data = System.Text.Encoding.UTF8.GetBytes(text);
    string method = "POST";

    client.UploadDataCompleted += new UploadDataCompletedEventHandler(UploadDataCallback2);
    client.UploadDataAsync(uri, method, data);
}
Public Shared Sub UploadDataInBackground2(ByVal address As String)

    Dim client As WebClient = New WebClient()
    Dim text As String = "Time = 12:00am temperature = 50"
    Dim data() As Byte = System.Text.Encoding.UTF8.GetBytes(text)
    Dim method As String = "POST"

    AddHandler client.UploadDataCompleted, AddressOf UploadDataCallback2
    Dim uri as Uri = New Uri(address)
                client.UploadDataAsync(uri, method, data)
End Sub

Metode berikut dipanggil ketika unggahan selesai.

void UploadDataCallback2( Object^ /*sender*/, UploadDataCompletedEventArgs^ e )
{
   array<Byte>^data = dynamic_cast<array<Byte>^>(e->Result);
   String^ reply = System::Text::Encoding::UTF8->GetString( data );
   Console::WriteLine( reply );
}
private static void UploadDataCallback2(Object sender, UploadDataCompletedEventArgs e)
{
    byte[] data = (byte[])e.Result;
    string reply = System.Text.Encoding.UTF8.GetString(data);

    Console.WriteLine(reply);
}
Private Shared Sub UploadDataCallback2(ByVal sender As Object, ByVal e As UploadDataCompletedEventArgs)

    Dim data() As Byte = CType(e.Result, Byte())
    Dim reply As String = System.Text.Encoding.UTF8.GetString(data)

    Console.WriteLine(reply)
End Sub
