C# '；项目被移动或删除'；Outlook.mailItem

我创建的outlook邮件如下所示：

 Outlook.Application outlookApp = new Outlook.Application();
 Outlook.MailItem mailItem = (Outlook.MailItem)outlookApp.CreateItem(Outlook.OlItemType.olMailItem);
 mailItem.Subject = mailSubject;
 mailItem.To = "";
 mailItem.Attachments.Add(totalPath);
 mailItem.Body = mailBody;
 mailItem.Importance = Outlook.OlImportance.olImportanceNormal;
 mailItem.Display(true);
 //Mail is send succesfully?

是否可以检查邮件是否成功发送或取消

编辑： 当我执行以下代码时，出现错误“项目已移动或删除”

Outlook.Application outlookApp = new Outlook.Application();
Outlook.MailItem mailItem = (Outlook.MailItem)outlookApp.CreateItem(Outlook.OlItemType.olMailItem);
mailItem.Subject = mailSubject;
mailItem.To = "";
mailItem.CC = "EDI.Orders@trust.com";
mailItem.Attachments.Add(totalPath);
mailItem.Body = mailBody;
mailItem.Importance = Outlook.OlImportance.olImportanceNormal;
mailItem.Display(true);
//Mail is send succesfully?
if (mailItem.Sent)
{
   MessageBox.Show("Sended");
}
else
{
   MessageBox.Show("canceled");
}

错误出现在mailItem.Sent。

我的问题是mailItem.Sent如何工作？

属性显示电子邮件是否已发送

此外，您还可以附加到

mailItem.Write

事件。（但要小心——也会被要求只进行储蓄等等）

属性返回一个布尔值，该值指示消息是否已发送

MailItem.Sent属性（Outlook）

返回一个布尔值，该值指示消息是否已发送。 只读

调用Display后检查此属性时，我怀疑由于该项不再处于活动状态，对

Sent

的调用失败。可以确认邮件是否确实已发送的一种方法是处理Outlook.Application类的事件

        Outlook.Application outlookApp = new Outlook.Application();

        outlookApp.ItemSend += new Outlook.ApplicationEvents_11_ItemSendEventHandler(outlookApp_ItemSend);

        Outlook.MailItem mailItem = (Outlook.MailItem)outlookApp.CreateItem(Outlook.OlItemType.olMailItem);
        mailItem.Subject = "Test";
        mailItem.To = "a.b@c.com";
        mailItem.CC = "";

        mailItem.Body = "Test Message";
        mailItem.Importance = Outlook.OlImportance.olImportanceNormal;
        mailItem.Display(true);

并在发送事件处理程序中检查消息

void outlookApp_ItemSend(object Item, ref bool Cancel)
{
    if (Item is Outlook.MailItem)
    {
        string subject = ((Outlook.MailItem)Item).Subject;


        if (subject == "Test")
        {
            //Item sent
        }


    }
}
