Definisi

Ruang nama:

System.Net

Rakitan:

System.Net.WebClient.dll

Sumber:

WebClient.cs

Menyediakan data untuk peristiwa tersebut UploadStringCompleted .

public ref class UploadStringCompletedEventArgs : System::ComponentModel::AsyncCompletedEventArgs

public class UploadStringCompletedEventArgs : System.ComponentModel.AsyncCompletedEventArgs

type UploadStringCompletedEventArgs = class
    inherit AsyncCompletedEventArgs

Public Class UploadStringCompletedEventArgs
Inherits AsyncCompletedEventArgs

UploadStringCompletedEventArgs

Contoh

Contoh kode berikut menunjukkan pengunggahan string secara asinkron.

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

Metode berikut dipanggil ketika unggahan selesai.

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

Keterangan

Instans kelas ini diteruskan ke UploadStringCompletedEventHandler.

Properti

Error	Mendapatkan nilai yang menunjukkan kesalahan mana yang terjadi selama operasi asinkron. (Diperoleh dari AsyncCompletedEventArgs)
Result	Mendapatkan balasan server ke operasi pengunggahan string yang dimulai dengan memanggil UploadStringAsync metode .
UserState	Mendapatkan pengidentifikasi unik untuk tugas asinkron. (Diperoleh dari AsyncCompletedEventArgs)
