Hãy thử điều này:
public List<AdxCalendarItem> GetAllCalendarItems()
{
Outlook.Application OutlookApp = new Outlook.Application();
List<AdxCalendarItem> result = new List<AdxCalendarItem>();
Outlook._NameSpace session = OutlookApp.Session;
if (session != null)
try
{
object stores = session.GetType().InvokeMember("Stores", BindingFlags.GetProperty, null, session, null);
if (stores != null)
try
{
int count = (int)stores.GetType().InvokeMember("Count", BindingFlags.GetProperty, null, stores, null);
for (int i = 1; i <= count; i++)
{
object store = stores.GetType().InvokeMember("Item", BindingFlags.GetProperty, null, stores, new object[] { i });
if (store != null)
try
{
Outlook.MAPIFolder calendar = null;
try
{
calendar = (Outlook.MAPIFolder)store.GetType().InvokeMember("GetDefaultFolder", BindingFlags.GetProperty, null, store, new object[] { Outlook.OlDefaultFolders.olFolderCalendar });
}
catch
{
continue;
}
if (calendar != null)
try
{
Outlook.Folders folders = calendar.Folders;
try
{
Outlook.MAPIFolder subfolder = null;
for (int j = 1; j < folders.Count + 1; j++)
{
subfolder = folders[j];
try
{
// add subfolder items
result.AddRange(GetAppointmentItems(subfolder));
}
finally
{ if (subfolder != null) Marshal.ReleaseComObject(subfolder); }
}
}
finally
{ if (folders != null) Marshal.ReleaseComObject(folders); }
// add root items
result.AddRange(GetAppointmentItems(calendar));
}
finally { Marshal.ReleaseComObject(calendar); }
}
finally { Marshal.ReleaseComObject(store); }
}
}
finally { Marshal.ReleaseComObject(stores); }
}
finally { Marshal.ReleaseComObject(session); }
return result;
}
List<AdxCalendarItem> GetAppointmentItems(Outlook.MAPIFolder calendarFolder)
{
List<AdxCalendarItem> result = new List<AdxCalendarItem>();
Outlook.Items calendarItems = calendarFolder.Items;
try
{
calendarItems.IncludeRecurrences = true;
Outlook.AppointmentItem appointment = null;
for (int j = 1; j < calendarItems.Count + 1; j++)
{
appointment = calendarItems[j] as Outlook.AppointmentItem;
try
{
AdxCalendarItem item = new AdxCalendarItem(
calendarFolder.Name,
appointment.Subject,
appointment.Location,
appointment.Start,
appointment.End,
appointment.Start.Date,
appointment.End.Date,

result.Add(item);
}
finally
{
{ Marshal.ReleaseComObject(appointment); }
}
}
}
finally { Marshal.ReleaseComObject(calendarItems); }
return result;
}
}
public class AdxCalendarItem
{
public string CalendarName;

{
this.CalendarName = CalendarName;

}
