我正在使用 VS 2010 ,Dot Net Framework 2.0 。我在 Extensibility->Shared Add-ins for Outlook 中创建了一个项目。
我想将 Outlook.MailItem 对象保存在 explorer_SelectionChange() 上的 DataTable 中,然后使用此 Outlook.MailItem 对象来操作主题和正文。
当我在数据表中保存 Mailitem 的对象时,它被保存为 SYS.ComAddins。这是代码类变量:
private Outlook.MailItem connectingMailItem;
private Outlook.Inspectors inspectors;
private Outlook.Application applicationObject;
private object addInInstance;
private Outlook.Explorer explorer;
DataTable dtMailItem = new DataTable();
连接:
explorer = this.Application.ActiveExplorer();
explorer.SelectionChange += new Outlook.ExplorerEvents_10_SelectionChangeEventHandler(explorer_SelectionChange);
dtMailItem.Columns.Add("MailItem",typeOf(Outlook.MailItem));
tFollowUp = new Timer();
tFollowUp.Interval = 100000;
tFollowUp.Tick += new EventHandler(tFollowUp_Tick);
explorer_SelectionChange
void explorer_SelectionChange()
{
if (connectingMailItem != null && connectingMailItem is Outlook.MailItem)
{
Marshal.ReleaseComObject(connectingMailItem);
// Perform a Garbage Collection
GC.Collect();
connectingMailItem = null;
return;
}
foreach (object selectedItem in explorer.Selection)
{
connectingMailItem = selectedItem as Outlook.MailItem;
break;
}
if (connectingMailItem != null && connectingMailItem is Outlook.MailItem)
{
dtMailItem.Rows.Add(connectingMailItem);
dtMailItem.AcceptChanges();
}
}
tFollowUp_Tick
void tFollowUp_Tick(object sender, EventArgs e)
{
if(dtMailItem.Rows.Count <= 0)
{
foreach(DataRow dr in dtMailItem.Rows)
{
// Manipulation code for subject and body or remove the Mailitem from Datatable
}
}
}
我如何保存 Mailitem 的对象或任何属性以识别保存了哪个 Mailitem
