Creating a Delivery Channel

A file delivery channel named StockWatchFileDeliveryChannel and an email delivery channel named StockWatchEmailDeliveryChannel are created in the CreateDeliveryChannel( ) method of Example 18-1. The code follows:

private static void CreateDeliveryChannel( )
{
  DeliveryChannelArgument dca;
 
  // add file delivery channel
  DeliveryChannel dcFile =
    new DeliveryChannel(nsi, 
    "StockWatchFileDeliveryChannel");
  dcFile.ProtocolName = "File";
  dca = new DeliveryChannelArgument
    (dcFile, "FileName");
  dca.Value = baseDirectoryPath + 
    @"\Notifications\FileNotifications.txt";
  dcFile.DeliveryChannelArguments.Add(dca);
  nsi.DeliveryChannels.Add(dcFile);
  Console.WriteLine("Added delivery channel: " 
    + dcFile.Name);
 
  // add email delivery channel
  DeliveryChannel dcEmail =
  new DeliveryChannel(nsi, "StockWatchEmailDeliveryChannel");
  dcEmail.ProtocolName = "SMTP";
  nsi.DeliveryChannels.Add(dcEmail);
  Console.WriteLine("Added delivery channel: " + dcEmail.Name);
}

You have to add at least one delivery channel to a Notification Services instance before creating it. The ProtocolName property of the DeliveryChannel object must be set to SMTP, File, or the name of a custom delivery protocol.

The NMO classes used to manage delivery channels are described in Table 18-3.
