。 。Outlook._AppointmentItem.get_UserProperties（）

at Microsoft.Office.Interop.Outlook._AppointmentItem.get_UserProperties()

        var calendar = outlookApplication.GetNamespace("MAPI").GetDefaultFolder(OlDefaultFolders.olFolderCalendar);

        if (calendar == null || calendar.Items == null)
        {
            return null;
        }

        var calendarItems = calendar.Items;

        if (calendarItems != null && calendarItems.Count > 0)
        {
            // Dont convert to LINQ or foreach please -> may cause Outlook memory leaks.
            for (int counter = 1; counter <= calendarItems.Count; counter++)
            {
                var appointment = calendarItems[counter] as AppointmentItem;

                if (appointment != null)
                {
                    var userProperty = appointment.UserProperties.Find("myInformation");

                    if (userProperty != null && userProperty.Value == myValue)
                    {
                        return appointment ;
                    }
                }
            }
        }

也许其appointment.UserProperties.Find（myInformation）收到COMException原因？

Maybe its appointment.UserProperties.Find("myInformation") cause COMException?

推荐答案

我发现这个解决方案。它不是必要使用查找事业限制让我需要什么。

I have found the solution for this. It isnt necessary to use Find cause Restrict make what I need.

...
string filter = string.Format("[myInformation] = '{0}'", myInformation);
var calendarItems = calendar.Items.Restrict(filter);
...
