将Excel电子表格从C添加到Outlook Appointment Body#

我用的是 Microsoft.Office.Interop.Outlook namepsace从C#app(WPF)创建Outlook约会提醒。我可以用一个简单的字符串作为主体:

var appt = (Outlook.AppointmentItem)Application.CreateItem(Outlook.OlItemType.olAppointmentItem);
appt.Subject = "Test Subject";
appt.Body = "Test Body";
...
...
appt.Save();
