Create and Save a Calendar in C# and VB.NET

GemBox.Email provides a comprehensive, but still a very easy-to-use API for working with calendars, events, tasks and reminders in C# and VB.NET. Calendars are defined by RFC 5545 standard, and they enable you to create reminders and alarms or to send invites, appointments, meeting requests, etc.

You can create a new Calendar object, or load it from an iCalendar file (.ics), or retrieve it from an email with the MailMessage.Calendars collection. Also, you can modify the Calendar object, save it as a new or existing iCalendar file or add it to the MailMessage.Calendars collection.

The following example shows how you can create a new Calendar with Event, Task and Reminder and then save it as a new iCalendar file.
