C# 计算已接受EWS会议的与会者人数

我正在努力统计接受EWS会议邀请的与会者人数

我能够通过模拟看到组织者的会议，并计算会议所需的与会者人数

        //Determine User to impersonat
        string impersonated_email = "user@domain";
        service.ImpersonatedUserId = new ImpersonatedUserId(ConnectingIdType.SmtpAddress, impersonated_email);

        //Bind User Calendar
        FolderId UserCalendarId = new FolderId(WellKnownFolderName.Calendar, impersonated_email);
        CalendarFolder UserCalendar = CalendarFolder.Bind(service, UserCalendarId);

        // Initialize values for the start and end times, and the number of appointments to retrieve.
        DateTime startDate = DateTime.Now.AddDays(0);
        DateTime endDate = startDate.AddDays(1);

        // Execute the search in the calendar folder and return the view
        CalendarView userCalendar = new CalendarView(startDate, endDate);
        userCalendar.PropertySet = new PropertySet(BasePropertySet.FirstClassProperties);
        FindItemsResults<Appointment> apt = service.FindAppointments(WellKnownFolderName.Calendar, userCalendar);

        foreach (Item item in apt.Items)
        {
            //Console.WriteLine(item.Subject);
            ServiceResponseCollection<GetItemResponse> myColl = service.BindToItems(new[] { new ItemId(item.Id.UniqueId) }, userCalendar.PropertySet);
            foreach (GetItemResponse temp in myColl)
            {
                Appointment app = (Appointment)temp.Item;
                Int32 Tn = app.RequiredAttendees.Count-1;
                Console.WriteLine(app.Subject + " " +Tn);
            }

//确定要模拟的用户
字符串模拟电子邮件=”user@domain";
service.ImpersonatedUserId=新的ImpersonatedUserId（ConnectingIdType.SmtpAddress，模拟电子邮件）；
//绑定用户日历
FolderId UserCalendarId=新的FolderId（WellKnownFolderName.Calendar，模拟电子邮件）；
CalendarFolder UserCalendar=CalendarFolder.Bind（服务，UserCalendarId）；
//初始化开始和结束时间以及要检索的约会数的值。
DateTime startDate=DateTime.Now.AddDays（0）；
DateTime endDate=startDate.AddDays（1）；
//在日历文件夹中执行搜索并返回视图
CalendarView userCalendar=新日历视图（开始日期、结束日期）；
userCalendar.PropertySet=新的PropertySet（BasePropertySet.FirstClassProperties）；
FindItemsResults apt=service.findAppoints（WellKnownFolderName.Calendar、userCalendar）；
foreach（apt.Items中的项目）
{
//Console.WriteLine（项目主题）；
ServiceResponseCollection myColl=service.BindToItems（new[]{new ItemId（item.Id.UniqueId）}，userCalendar.PropertySet）；
foreach（myColl中的GetItemResponse温度）
{
约会应用=（约会）临时项目；
Int32 Tn=app.requiredAttenders.Count-1；
Console.WriteLine（app.Subject+“”+Tn）；
}

我还想看看有多少必要的与会者接受了会议邀请

问候

您应该能够获得如下响应类型：

Appointment app;

int count = app.RequiredAttendees.Count(x => (x.ResponseType.HasValue && x.ResponseType.Value == MeetingResponseType.Accept));
