.NET:获取所有Outlook日历项

Question

如何从特定日历(特定日期)获取所有项目.让我们说比如每周一晚上我有一个带有重复项目的日历.当我请求所有这样的项目时:

CalendarItems = CalendarFolder.Items;
CalendarItems.IncludeRecurrences = true;

我只买1件......

是否有一种简单的方法可以从日历中获取所有项目(主要项目+派生项目)？在我的具体情况下,可以设置一个日期限制,但只是为了获得所有项目(我的经常性项目本身是时间限制的)很酷.

我正在使用Microsoft Outlook 12对象库(Microsoft.Office.Interop.Outlook).

我研究了文档,这是我的结果:我已经将一个月的时间限制硬编码,但这只是一个例子.

public void GetAllCalendarItems()
{
    Microsoft.Office.Interop.Outlook.Application oApp = null;
    Microsoft.Office.Interop.Outlook.NameSpace mapiNamespace = null;
    Microsoft.Office.Interop.Outlook.MAPIFolder CalendarFolder = null;
    Microsoft.Office.Interop.Outlook.Items outlookCalendarItems = null;

    oApp = new Microsoft.Office.Interop.Outlook.Application();
    mapiNamespace = oApp.GetNamespace("MAPI"); ;
    CalendarFolder = mapiNamespace.GetDefaultFolder(Microsoft.Office.Interop.Outlook.OlDefaultFolders.olFolderCalendar);
    outlookCalendarItems = CalendarFolder.Items;
    outlookCalendarItems.IncludeRecurrences = true;

    foreach (Microsoft.Office.Interop.Outlook.AppointmentItem item in outlookCalendarItems)
    {
        if (item.IsRecurring)
        {
            Microsoft.Office.Interop.Outlook.RecurrencePattern rp = item.GetRecurrencePattern();
            DateTime first = new DateTime(2008, 8, 31, item.Start.Hour, item.Start.Minute, 0);
            DateTime last = new DateTime(2008, 10, 1);
            Microsoft.Office.Interop.Outlook.AppointmentItem recur = null;



            for (DateTime cur = first; cur <= last; cur = cur.AddDays(1))
            {
                try
                {
                    recur = rp.GetOccurrence(cur);
                    MessageBox.Show(recur.Subject + " -> " + cur.ToLongDateString());
                }
                catch
                { }
            }
        }
        else
        {
            MessageBox.Show(item.Subject + " -> " + item.Start.ToLongDateString());
        }
    }

}

我相信您必须限制或查找以获得定期约会,否则Outlook将不会扩展它们.此外,您必须在设置IncludeRecurrences 之前按开始排序.

Answer 3

我写了类似的代码,但后来发现了导出功能:

Application outlook;
NameSpace OutlookNS;

outlook = new ApplicationClass();
OutlookNS = outlook.GetNamespace("MAPI");

MAPIFolder f = OutlookNS.GetDefaultFolder(OlDefaultFolders.olFolderCalendar);

CalendarSharing cs = f.GetCalendarExporter();
cs.CalendarDetail = OlCalendarDetail.olFullDetails;
cs.StartDate = new DateTime(2011, 11, 1);
cs.EndDate = new DateTime(2011, 12, 31);
cs.SaveAsICal("c:\\temp\\cal.ics");

LinqPad 剪断了对我有用：

//using Microsoft.Office.Interop.Outlook
Application a = new Application();
Items i = a.Session.GetDefaultFolder(OlDefaultFolders.olFolderCalendar).Items;
i.IncludeRecurrences = true;
i.Sort("[Start]");
i = i.Restrict(
    "[Start] >= '10/1/2013 12:00 AM' AND [End] < '10/3/2013 12:00 AM'");


var r =
    from ai in i.Cast<AppointmentItem>()
    select new {
        ai.Categories,
        ai.Start,
        ai.Duration
        };
r.Dump();
