Příklady

Následující příklad kódu ukazuje implementaci obslužné rutiny DownloadProgressChanged pro událost. Metoda zobrazí hodnotu TotalBytesToReceive vlastnosti.

static void UploadProgressCallback(Object^ sender,
          UploadProgressChangedEventArgs^ e)
      {
          // Displays the operation identifier, and the transfer progress.
          Console::WriteLine("{0}    uploaded {1} of {2} bytes. {3} % complete...",
              (String ^)e->UserState,
              e->BytesSent,
              e->TotalBytesToSend,
              e->ProgressPercentage);
      }
static void DownloadProgressCallback(Object^ sender,
          DownloadProgressChangedEventArgs^ e)
      {
          // Displays the operation identifier, and the transfer progress.

Poznámky

Pokud chcete zjistit počet přijatých bajtů, použijte BytesReceived vlastnost .

Pokud chcete zjistit, k jakému procentu došlo k převodu ProgressPercentage , použijte vlastnost .
