Outlook中约会和联系人的EventHandler
Outlook中约会和联系人的EventHandler
提问于 2012-03-21 21:00:15
我想使用EventHandlers进行约会和联系人(以及稍后的任务)。
我有一个ContactProgram类，它执行以下代码：
Outlook.Items myContactItems = myApplication.Session.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderContacts).Items;
myContactItems.ItemAdd += new Outlook.ItemsEvents_ItemAddEventHandler(myContactItems_Add);
myContactItems.ItemChange += new Outlook.ItemsEvents_ItemChangeEventHandler(myContactItems_Change);
myContactItems.ItemRemove += new Outlook.ItemsEvents_ItemRemoveEventHandler(myContactItems_Remove);我有一个AppointmentPogram类，它执行以下代码：
Outlook.Items myAppointmentItems = myApplication.Session.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderCalendar).Items;
myAppointmentItems.ItemAdd += new Outlook.ItemsEvents_ItemAddEventHandler(myAppointmentItems_Add);
myAppointmentItems.ItemChange += new Outlook.ItemsEvents_ItemChangeEventHandler(myAppointmentItems_Change);
myAppointmentItems.ItemRemove += new Outlook.ItemsEvents_ItemRemoveEventHandler(myAppointmentItems_Remove);如果我对这两个都使用EventHandler，那么Appointment EventHandler就不会触发。但是如果我注释掉创建Contact-EventHandler的代码，那么就会触发Appointment EventHandler。(在我的程序中，首先创建contact-EventHandler，然后创建Appointment EventHandler。)
我可以只创建一次EventHandlers，然后检查作为参数给定的对象的类型。但不幸的是，contact-EventHandlers需要指向olFolderContacts和appointment Eventhandlers。
有什么建议吗？
编辑:我的新代码：
...
using Outlook = Microsoft.Office.Interop.Outlook;
using Office = Microsoft.Office.Core;
public partial class ThisAddIn
{
private static Outlook.Application myApplication = new Outlook.Application();
private List<OutlookContact> allContacts = new List<OutlookContact>();
private Outlook.Folder myContactsFolder = (Outlook.Folder)myApplication.Session.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderContacts);
private ContactProgram contactProgram;
private List<OutlookAppointment> allAppointments = new List<OutlookAppointment>();
private Outlook.Folder myAppointmentsFolder = (Outlook.Folder)myApplication.Session.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderCalendar);
private AppointmentProgram appointmentProgram;
private void ThisAddIn_Startup(object sender, System.EventArgs e)
{
contactProgram = new ContactProgram(myApplication, allContacts, myContactsFolder);
contactProgram.Start();
appointmentProgram = new AppointmentProgram(myApplication, allAppointments, myAppointmentsFolder);
appointmentProgram.Start();
//initialise EventHandlers
//myContactItems = myApplication.Session.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderContacts).Items;//= myContactsFolder.Items;
Outlook.Items myContactItems = myContactsFolder.Items;
myContactItems.ItemAdd += new Outlook.ItemsEvents_ItemAddEventHandler(myContactItems_Add);
myContactItems.ItemChange += new Outlook.ItemsEvents_ItemChangeEventHandler(myContactItems_Change);
myContactItems.ItemRemove += new Outlook.ItemsEvents_ItemRemoveEventHandler(myContactItems_Remove);
//myAppointmentItems = myApplication.Session.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderCalendar).Items;
Outlook.Items myAppointmentItems = myAppointmentsFolder.Items;
myAppointmentItems.ItemAdd += new Outlook.ItemsEvents_ItemAddEventHandler(myAppointmentItems_Add);
myAppointmentItems.ItemChange += new Outlook.ItemsEvents_ItemChangeEventHandler(myAppointmentItems_Change);
myAppointmentItems.ItemRemove += new Outlook.ItemsEvents_ItemRemoveEventHandler(myAppointmentItems_Remove);
}
private static void myContactItems_Add(object item)
{
ContactProgram.myContactItems_Add(item);
}

您寻找的事件处理程序(ItemAdd、ItemChange、ItemRemove)是在Folder级别完成的。由于日历和联系人是不同的文件夹-您不能使用单个注册同时侦听这两个文件夹中的更改事件-因此每个Folder存储都需要单独的处理程序。
如果您的事件没有触发，很可能是由于作用域问题，您没有将变量myAppointmentItems和myContactItems保留为类级别变量。参见related SO post。
