Question

我一直在搜索EWS pullsubscription示例，该示例允许我获取自用户启动以来已为用户创建或修改的日历事件列表。我有工作代码来获取收件箱的这些信息，但我还没有找到一个很好的例子来说明如何为日历做这个。

以下是收件箱的示例;任何人都可以为我提供链接或代码示例，以使用Exchange Web服务请求订阅完成日历事件或约会相同的事情吗？

    ExchangeService service;
    PullSubscription subscriptionInbox;

    private void SetService() {
        service = new ExchangeService(ExchangeVersion.Exchange2007_SP1);
        service.Url = new Uri("https://mail.myserver.com/EWS/Exchange.asmx");
    }

    private void SetSubscription() {
        if(service == null) {
            SetService();
        }
        // Subscribe to pull notifications in the Inbox folder, and get notified when
        // a new mail is received, when an item or folder is created, or when an item
        // or folder is deleted. 
        subscriptionInbox = service.SubscribeToPullNotifications(
        new FolderId[] { WellKnownFolderName.Inbox },
        5 /* timeOut: the subscription will end if the server is not polled within 5 minutes. */,
        null /* watermark: null to start a new subscription. */,
        EventType.NewMail, EventType.Modified);
    }

    private void btnGetLatestMessages_Click(object sender, EventArgs e) {
        if(subscriptionInbox == null) {
            SetSubscription();
        }
        GetEventsResults eventsInbox = subscriptionInbox.GetEvents();
        EmailMessage message;
        // Loop through all item-related events.
        foreach(ItemEvent itemEvent in eventsInbox.ItemEvents) {
            switch(itemEvent.EventType) {
                case EventType.NewMail:
                    try {
                        Item item = Item.Bind(service, itemEvent.ItemId);
                        if(item.ItemClass.ToLower() == "IPM.Note".ToLower()) {
                            message = EmailMessage.Bind(service, itemEvent.ItemId);
                            MessageBox.Show("Inbox/NewMail - " + message.Subject);
                        }
                    } catch(Exception ex) {
                        MessageBox.Show("EventType.NewMail - " + itemEvent.ItemId);
                    }
                    break;
                case EventType.Modified:
                    try {
                        Item item = Item.Bind(service, itemEvent.ItemId);
                        if(item.ItemClass.ToLower() == "IPM.Note".ToLower()) {
                            message = EmailMessage.Bind(service, itemEvent.ItemId);
                            MessageBox.Show("Inbox/Modified - " + message.Subject);
                        }
                    } catch(Exception ex) {
                        MessageBox.Show("EventType.NewMail - " + itemEvent.ItemId);
                    }
                    break;
            }
        }
    }

只需订阅日历，而不是订阅指定事件类型的收件箱。

var subscriptionCalendar = service.SubscribeToPullNotifications(
    new[] { new FolderId(WellKnownFolderName.Calendar) }, 
    1440, 
    null, 
    EventType.Created, EventType.Modified);

或者，您可以使用所需的FolderId(WellKnownFolderName.Inbox)为FolderId(WellKnownFolderName.Calendar)和EventType创建一个拉动通知。

EWS PullSubscription用于新的或修改的日历事件
