我为每个AppointmentItem
的发送事件添加了一个事件处理程序。这个事件处理程序只是做一些日志记录。我通过Outlook 2003创建会议,然后两次更新会议。最后我查了一下日志。
this.Application.Inspectors.NewInspector += new Microsoft.Office.Interop.Outlook.InspectorsEvents_NewInspectorEventHandler(_inspectors_NewInspector);
private void _inspectors_NewInspector(Microsoft.Office.Interop.Outlook.Inspector inspector)
{
if(inspector.CurrentItem is Outlook.AppointmentItem)
{
_appointmentEvent = inspector.CurrentItem as Outlook.ItemEvents_10_Event;
_appointmentEvent.Send += new Microsoft.Office.Interop.Outlook.ItemEvents_10_SendEventHandler(_appointmentEvent_Send);
}
}
private void _appointmentEvent_Send(ref bool Cancel)
{
Log.WriteLog("InspectorWrapper: _appointmentEvent_Send Enter");
Log.WriteLog("InspectorWrapper: _appointmentEvent_Send Exit");
}
我检查日志。我发现send事件处理程序将被多次调用。

为什么?
答案 0 :(得分:0)
您应该向NewInspector
事件添加日志记录,以查看您锁定AppointmentItem.Send
事件的次数。我的假设是NewInspector
是你的问题。最佳做法是使用自定义InspectorWrapper
作为容器来管理活动检查器列表,以避免多个事件锁定。
如需参考,请查看this MSDN reference中的FindOutlookInspector
。
internal static List<OutlookInspector> m_Windows;
internal static OutlookInspector FindOutlookInspector(object window)
{
foreach (OutlookInspector inspector in m_Windows)
if (inspector.Window == window)
return inspector;
return null;
}
