如何:以编程方式确定新事件处理程序的当前Outlook项
如何:以编程方式确定新事件处理程序的当前Outlook项
提问于 2022-10-21 20:28:27
如主题所示，我正在尝试确定Outlook项是否为会议请求，同时创建一个新的.ItemSend事件处理程序。我已经和探长和探险家一起研究过这样做的方法。
我曾检讨过：
这是：
ActiveExplorer().Selection returns previously selected mail in Outlook C#
还有一些类似的问题。
我已经成功地建立了一个新的检查器事件处理程序，并为Application.ItemSend定义了事件处理程序，这些处理程序非常有效。但只有当我发出会面请求的时候。定期的电子邮件响应事件触发器，但重新启动Outlook，将电子邮件保存为草稿，而不发送。
我不确定如何结合使用审查员和浏览器来防止Outlook崩溃？我不确定我能不能只用检查员来做这件事？只使用资源管理器？
我相信，如果我能够将所有这些代码包装为将outlook项标识为MailItem或会议请求，我就可以通过电子邮件和新的事件处理程序来解决这个问题。
正确的方向上的一点是值得赞赏的。-谢谢--克里斯

AppointmentItem从不发送，因此也不会传递给Application.ItemSend事件。您得到的是MeetingItem对象。如果需要父约会，请调用MeetingItem.GetAssociatedAppointment。

触发Explorer事件时不需要使用NewInspector窗口：
void Inspectors_NewInspector(Microsoft.Office.Interop.Outlook.Inspector Inspector)
{
// <testing this>
Outlook.Selection sel = Application.ActiveExplorer().Selection;使用作为参数传递给事件处理程序的Inspector实例。
我还注意到ItemSend事件处理程序中的以下代码：
public void Application_ItemSend(object Item, ref bool Cancel)
{
// use EventId to identify current meeting request
var app = new Microsoft.Office.Interop.Outlook.Application();
var ns = app.Session;每次触发事件时，都不需要创建新的Outlook Application实例。改为使用外接程序类的Application属性(在ThisAddIn类中可用)。
此外，您还需要使用作为参数传递给Item事件处理程序的ItemSend对象，所以不要使用以下代码：
Outlook.AppointmentItem meeting = ns.GetItemFromID(objUserPropertyEventId.Value);
MessageBox.Show(meeting.Subject);检查对象是否属于特定类型：
if (Item is Outlook.MeetingItem)您可以尝试将Item对象强制转换为特定类型，然后检查是否为null。
var obj = Item as Outlook.MeetingItem;
if (obj != null)
