使用例

非同期的に文字列をアップロードするコード例を次に示します。

Visual Basic

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

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);
}

アップロードが完了すると次のメソッドが呼び出されます。

Visual Basic

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

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