Question

您好我想获得Outlook发送的附件和邮件的收件人主题...我能够通过Outlook的默认文件夹获取它。如何在发送邮件之前通过VSTO检索发送的邮件。

现在我正在这样做

namespace OutlookAddInAttachment
{
    public partial class ThisAddIn
    {
        private void ThisAddIn_Startup(object sender, System.EventArgs e)
        {
            this.Application.NewMail += new Microsoft.Office.Interop.Outlook.ApplicationEvents_11_NewMailEventHandler(ThisApplication_NewMail);

    }

    private void ThisApplication_NewMail()
    {
        Outlook.MAPIFolder SentMail = this.Application.ActiveExplorer().Session.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderOutbox);
        Outlook.Items SentMailItems = SentMail.Items;
        Outlook.MailItem newEmail = null;
        //SentMailItems = SentMailItems.Restrict("[Unread] = true");
        try
        {
            foreach (object collectionItem in SentMailItems)
            {
                newEmail = collectionItem as Outlook.MailItem;
                if (newEmail != null)
                {
                    if (newEmail.Attachments.Count > 0)
                    {
                        for (int i = 1; i <= newEmail.Attachments.Count; i++)
                        {
                            newEmail.Attachments[i].SaveAsFile(@"C:\TestFileSave\" + newEmail.Attachments[i].FileName);
                        }
                    }
                }
            }
        }
        catch (Exception ex)
        {
            string errorInfo = (string)ex.Message
                .Substring(0, 11);
            if (errorInfo == "Cannot save")
            {
                MessageBox.Show(@"Create Folder C:\TestFileSave");
            }
        }
    }

我不确定你到底想要做什么。

您正在侦听NewMail事件，该事件侦听INBOX中的新RECEIVED邮件，然后扫描已发送邮件文件夹，根据定义，该文件夹仅包含已发送的邮件。

如果您要做的是截取正在发送的新邮件的附件，那么您需要的是ItemSend事件，这将允许您在发送之前捕获它：

public partial class ThisAddIn
{

private void ThisAddIn_Startup(object sender, System.EventArgs e)
{
    this.Application.ItemSend += new Microsoft.Office.Interop.Outlook.ApplicationEvents_11_ItemSendEventHandler(ThisApplication_ItemSend);
}

private void ThisApplication_ItemSend(object item, bool cancel)
{
    Outlook.MailItem newEmail = item as MailItem;
    if (newEmail != null)
    {
        foreach (var attachment in newEmail.Attachments)
        {
            attachment.SaveAsFile(@"C:\TestFileSave\" + attachment.FileName);
        }
    }
}

}
