Question

我写了一个VSTO功能区按钮来批量更改现有MailItem上的主题。但是，它不是100％的工作时间。我怀疑在主题更改后要求我保存电子邮件的提示阻止了主题更改。

如何以编程方式抑制对话框，以便我可以批量更改主题，然后取消禁止对话框。

public void EditSubject()
{
    var explorer = _OutlookApplication.ActiveExplorer();
    var selection = explorer.Selection;
    List<MailItem> mailItems = new List<MailItem>();
    foreach(var item in selection)
    {
        var mailitem = item as MailItem;
        if(mailitem != null) mailItems.Add(mailitem);
    }

    if(mailItems.Count > 0)
    {
        using (var form = new FormEditSubject())
        {
            form.Subject = mailItems[0].Subject;

            if (form.ShowDialog() == System.Windows.Forms.DialogResult.OK)
            {
                // changing subject works, but does not work 100% of the time.
                // Save prompt dialog shows when closing outlook.
                mailItems.ForEach(item => item.Subject = form.Subject);
                System.Windows.Forms.MessageBox.Show(string.Format("{0} MailItems subject edited to: {1}", mailItems.Count, form.Subject));
            }
        }
    }
}

修改主题属性后，您永远不会调用MailItem.Save()

Outlook VSTO禁用提示，要求在主题更改后保存邮件
