我目前正在开发一款应用,可以检查一个或多个用户日历,查看特定类别下的约会/会议。
刚开始使用EWS时,我一直在尝试找到一个解决方案,以便按类别获取日历项目(约会或会议)或确定约会是否具有特定类别。我目前有以下代码(exService = ExchangeService对象):
foreach (Appointment a in exService.FindItems(WellKnownFolderName.Calendar, new ItemView(int.MaxValue)))
{
//Need to check if appointment has category f.x.: "SMS"
}
有人知道如何实现这一目标吗?

当您查询约会时,您想要使用FindAppointments和日历视图,而不是使用FindItems,这将确保扩展任何定期约会,例如参见https://msdn.microsoft.com/en-us/library/office/dn495614(v=exchg.150).aspx
使用类别您需要做的就像
DateTime startDate = DateTime.Now;
DateTime endDate = startDate.AddDays(60);
const int NUM_APPTS = 1000;
// Initialize the calendar folder object with only the folder ID.
CalendarFolder calendar = CalendarFolder.Bind(service, WellKnownFolderName.Calendar, new PropertySet());
// Set the start and end time and number of appointments to retrieve.
CalendarView cView = new CalendarView(startDate, endDate, NUM_APPTS);
// Limit the properties returned to the appointment's subject, start time, and end time.
cView.PropertySet = new PropertySet(AppointmentSchema.Subject, AppointmentSchema.Start, AppointmentSchema.End,AppointmentSchema.Categories);
// Retrieve a collection of appointments by using the calendar view.
FindItemsResults<Appointment> appointments = calendar.FindAppointments(cView);
Console.WriteLine("\nThe first " + NUM_APPTS + " appointments on your calendar from " + startDate.Date.ToShortDateString() +
" to " + endDate.Date.ToShortDateString() + " are: \n");
foreach (Appointment a in appointments)
{
if (a.Categories.Contains("Green"))
{
Console.Write("Subject: " + a.Subject.ToString() + " ");
Console.Write("Start: " + a.Start.ToString() + " ");
Console.Write("End: " + a.End.ToString());
}
Console.WriteLine();
}
