Question

我想知道如何将电子邮件作为附件附加到C＃中的另一封电子邮件中。详细说明：

我正在为outlook
我在这一行收到错误：附件attach = new Attachment（mailItem，new System.Net.Mime.ContentType（“text / html; charset = us-ascii”））;
错误消息是：无法创建抽象类或接口的实例'Microsoft.Office.Interop.Outlook.Attachment'

以下示例代码

private void button1_Click(object sender, RibbonControlEventArgs e)
{
    Explorer explorer = Globals.ThisAddIn.Application.ActiveExplorer();
    Selection selection = explorer.Selection;

    if (selection.Count > 0)   // Check that selection is not empty.
    {
        object selectedItem = selection[1];   // Index is one-based.
        MailItem mailItem = selectedItem as MailItem;


        if (mailItem != null)    // Check that selected item is a message.
        {
            System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage();
            message.To.Add("blah@blah.com");
            message.Subject = "blah";
            message.From = new System.Net.Mail.MailAddress("test@test.com");
            message.Body = "This is the message body";

             Attachment attach = new Attachment(mailItem, new System.Net.Mime.ContentType("text/html; charset=us-ascii"));
             message.Attachments.Add(attach);
            System.Net.Mail.SmtpClient smtp = new System.Net.Mail.SmtpClient("smlsmtp");
            smtp.Send(message);

        }
    }
}

在做了一些阅读/搜索后，我找到了有用的东西。可能最困难的部分是第一行。

                try
                {
                    Outlook.MailItem tosend = (Outlook.MailItem)Globals.ThisAddIn.Application.CreateItem(Outlook.OlItemType.olMailItem);
                    tosend.Attachments.Add(mailItem);
                    tosend.To = "blah@blah.com";
                    tosend.Subject = "test";
                    tosend.Body = "blah";
                    tosend.Save();
                    tosend.Send();
                }
                catch (Exception ex)
                {
                    Console.WriteLine("{0} Exception caught: ", ex);
                }
