Load a Calendar
With GemBox.Email you can load a Calendar from a file or a stream in iCalendar format (.ics). The loaded Calendar can be modified, saved or added to a MailMessage object.
The following example shows how you can load a Calendar from an iCalendar file (.ics) and display its properties and components, such as tasks and events, using the GemBox.Email library.
using GemBox.Email;
using GemBox.Email.Calendar;
using System;
class Program
{
static void Main()
{
// If using the Professional version, put your serial key below.
ComponentInfo.SetLicense("FREE-LIMITED-KEY");
// Load calendar.
Calendar calendar = Calendar.Load("%InputFileName%");
Console.WriteLine("CALENDAR");
Console.WriteLine($"Method: {calendar.Method}");
Console.WriteLine($"Events count: {calendar.Events.Count}");
Console.WriteLine($"Tasks count: {calendar.Tasks.Count}");
// Iterate through all events.
Console.WriteLine();
foreach (Event ev in calendar.Events)
{
Console.WriteLine("- EVENT");
Console.WriteLine($"Organizer: {ev.Organizer}");
Console.WriteLine($"Name: {ev.Name}");
Console.WriteLine($"Start: {ev.Start:G}");
Console.WriteLine($"End: {ev.End:G}");
Console.WriteLine($"Reminders count: {ev.Reminders.Count}");
// Iterate through all reminders.
foreach (Reminder reminder in ev.Reminders)
{
Console.WriteLine("-- REMINDER");
Console.WriteLine($"Action: {reminder.ReminderAction}");
Console.WriteLine($"Days to trigger before start: {reminder.TriggerBeforeStart?.Days}");
}
}
// Iterate through all tasks.
Console.WriteLine();
foreach (Task task in calendar.Tasks)
{
Console.WriteLine("- TASK");
Console.WriteLine($"Organizer: {task.Organizer}");
Console.WriteLine($"Name: {task.Name}");
Console.WriteLine($"Start: {task.Start:G}");
Console.WriteLine($"Deadline: {task.Deadline:G}");
Console.WriteLine($"Reminders count: {task.Reminders.Count}");
// Iterate through all reminders.
foreach (Reminder reminder in task.Reminders)
{
Console.WriteLine("-- REMINDER");
Console.WriteLine($"Action: {reminder.ReminderAction}");
Console.WriteLine($"Days to trigger before start: {reminder.TriggerBeforeStart?.Days}");
}
}
}
}
