Export

The iCalendarExporter class allows you to export appointments. Follow the steps below to export scheduler appointments to the iCalendar format.

1. Create an iCalendarExporter class instance in code.

   C#

   iCalendarExporter exporter = new iCalendarExporter(Scheduler.Storage);
   

   VB.NET

   Dim exporter As New iCalendarExporter(Scheduler.Storage)
   

2. Create a stream and pass it to the AppointmentExporter.Export method.

   C#

   using(MemoryStream memoryStream = new MemoryStream()) {
       exporter.Export(memoryStream);
       ...
   }
   

   VB.NET

   Using memoryStream As New MemoryStream()
       exporter.Export(memoryStream)
      ...
   End Using
   

3. The stream now contains appointment data in the iCalendar format. You can save the stream’s content on server or pass this content to the client by writing it to the HTTP output.

   C#

   Stream outputStream = Response.OutputStream;
   memoryStream.WriteTo(outputStream);
   outputStream.Flush();
   

   VB.NET

   Dim outputStream As Stream = Response.OutputStream
   memoryStream.WriteTo(outputStream)
   outputStream.Flush()
