使用 Exchange Web 服務參加會議的時間

Question

我想知道我們作為一個部門（約 100 人）在會議上花費了多少時間。 為簡單起見，我們可以將所有繁忙時間視為開會時間。 但是我不知道該怎么做，我希望有人有想法

網絡上有使用 EWS API 處理此類事情的示例。 例如，您可以使用的想法：

使用 EWS 托管 API 獲取約會。 下面的代碼示例演示如何使用 EWS 托管 API 檢索用戶在指定開始時間和結束時間之間的約會。

// Initialize values for the start and end times, and the number of appointments to retrieve.
            DateTime startDate = DateTime.Now;
            DateTime endDate = startDate.AddDays(30);
            const int NUM_APPTS = 5;
            // 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);
            // 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)
            {
                Console.Write("Subject: " + a.Subject.ToString() + " ");
                Console.Write("Start: " + a.Start.ToString() + " ");
                Console.Write("End: " + a.End.ToString());
                Console.WriteLine();
            }
