Assembly:  System (in System.dll)
public:
property long long TotalBytesToReceive {
	long long get ();
}

Property Value

Type: System::Int64
An Int64 value that indicates the number of bytes that will be received.

To determine the number of bytes already received, use the BytesReceived property.

To determine what percentage of the transfer has occurred, use the ProgressPercentage property.

The following code example shows an implementation of a handler for the DownloadProgressChanged event. The method displays the value of this property.

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.
          Console::WriteLine("{0}    downloaded {1} of {2} bytes. {3} % complete...", 
              (String ^)e->UserState, 
              e->BytesReceived, 
              e->TotalBytesToReceive,
              e->ProgressPercentage);
      }
