保存Outlook约会后的事件

Question

我正在编写一个Outlook加载项,并希望在保存之后(何时)使用约会的数据执行某些操作(此处不相关).
(我是Outlook-Addins的新手)
所以我发现有一个AfterWrite事件,我可以注册一个方法.Application上有一个ItemLoad事件.

所以我的第一个Efford是这样的:

private void ThisAddIn_Startup(object sender, System.EventArgs e)
{
    // ...
    this.Application.ItemLoad += 
        new Outlook.ApplicationEvents_11_ItemLoadEventHandler(atItemLoad);
}
public void atItemLoad(Object item)
{
    Outlook.AppointmentItem aitem = item as Outlook.AppointmentItem;
    if (aitem != null)
    {
        aitem.AfterWrite += 
            new Outlook.ItemEvents_10_AfterWriteEventHandler(afterWrite);
    }
}
public void afterWrite()
{
    // Who was written?
    MessageBox.Show("it was written!");
}

问题是,我不知道如何获取约会的数据,这引发了事件. Application.ItemLoad注册一个获取Object的函数,该函数可以强制转换为约会.
AfterWrite没有.我想要这样的事情:

public void afterWrite(Outlook.AppointmentItem aitem)
{
    // do something with the data from the Appointment
    MessageBox.Show(aitem.Subject + " was written!");
}

我担心我正在研究完全错误的方向..

*对不起,如果我的英语很乱 - 这不是我的母语

编辑:

我甚至试过这样的结构:

private List<AppointmentEventHolder> holderList = new List<AppointmentEventHolder>();

internal class AppointmentEventHolder
{
    private Outlook.AppointmentItem aitem = null;
    public AppointmentEventHolder(Outlook.AppointmentItem item)
    {
        aitem = item;
    }

    public void onWrite()
    {
        MessageBox.Show("write: " + aitem.Subject);
    }
}

public void atItemLoad(Object item)
{
    Outlook.AppointmentItem aitem = item as Outlook.AppointmentItem;
    if (aitem != null)
    {
        AppointmentEventHolder aHolder = new AppointmentEventHolder(aitem);
        holderList.Add(aHolder);
        aitem.AfterWrite += aHolder.onWrite;
    }
}

但事件不会被解雇!我现在非常沮丧

好吧,我想我得到了这个.
您必须在具有约会的文件夹上注册处理程序.

我阅读并体验了自己,保存对您注册事件的对象的引用至关重要,所以我这样做了.
这就是代码

private Outlook.MAPIFolder _CalendarFolder = null;
private Outlook.Items _CalendarItems = null;

private void ThisAddIn_Startup(object sender, System.EventArgs e)
{
    Outlook.MAPIFolder calendarFolder =
        this.Application.ActiveExplorer().Session.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderCalendar);

    // get the Termine24-Folder (if not found, create it)
    try
    {
        _CalendarFolder = calendarFolder.Folders[Constants.FOLDERNAME];
    }
    catch
    {
        _CalendarFolder = calendarFolder.Folders.Add(Constants.FOLDERNAME);
    }
    _CalendarItems = _CalendarFolder.Items;
    attachEvents();

}
public void attachEvents()
{
    _CalendarItems.ItemAdd += Item_Add;
    _CalendarItems.ItemChange += Item_Change;
    _CalendarItems.ItemRemove += Item_Remove;
}
public void Item_Add(Object item)
{
    Outlook.AppointmentItem aitem = item as Outlook.AppointmentItem;
    if (aitem != null)
    {
        MessageBox.Show("add: " + aitem.Subject);
    }
    else
    {
        MessageBox.Show("add, but no appointment");
    }
}
public void Item_Change(Object item)
{
    Outlook.AppointmentItem aitem = item as Outlook.AppointmentItem;
    if (aitem != null)
    {
        MessageBox.Show("changed: " + aitem.Subject);
    }
    else
    {
        MessageBox.Show("change, but no appointment");
    }
}
public void Item_Remove()
{
    MessageBox.Show("Item_remove");
}

好的方面是,如果约会在概述中被拖放,我现在也会得到一个事件.

但是Item_Remove仍然没有让我删除被删除的对象.
