public byte[] Result { get; }

member this.Result : byte[]

Public ReadOnly Property Result As Byte()

Byte 陣列，包含伺服器回應。

範例

下列程式代碼範例會顯示此屬性的值。

void UploadFileCallback2( Object^ /*sender*/, UploadFileCompletedEventArgs^ e )
{
   String^ reply = System::Text::Encoding::UTF8->GetString( e->Result );
   Console::WriteLine( reply );
}

private static void UploadFileCallback2(Object sender, UploadFileCompletedEventArgs e)
{
    string reply = System.Text.Encoding.UTF8.GetString(e.Result);
    Console.WriteLine(reply);
}

Private Shared Sub UploadFileCallback2(ByVal sender As Object, ByVal e As System.Net.UploadFileCompletedEventArgs)

    Dim reply As String = System.Text.Encoding.UTF8.GetString(e.Result)
    Console.WriteLine(reply)
End Sub

備註

您應該檢查 Error 和 Cancelled 屬性，以判斷上傳是否已完成。 Error如果屬性的值是Exception物件，或Cancelled屬性的值是 true，異步操作未正確完成，而且Result屬性值無效。
