C＃MailTo与附件？

目前，我正在使用以下方法打开用户的Outlook电子邮件帐户，并在电子邮件中填充相关内容以进行发送：

public void SendSupportEmail(string emailAddress, string subject, string body)
{
   Process.Start("mailto:" + emailAddress + "?subject=" + subject + "&body=" 
                + body);
}

但是，我希望能够用附件填充电子邮件。

就像是：

public void SendSupportEmail(string emailAddress, string subject, string body)
{
   Process.Start("mailto:" + emailAddress + "?subject=" + subject + "&body=" 
      + body + "&Attach="
      + @"C:\Documents and Settings\Administrator\Desktop\stuff.txt");
}

但是，这似乎不起作用。有谁知道一种可以使之工作的方法！？

帮助极大的赞赏。

问候。

mailto：不正式支持附件。我听说Outlook 2003将使用以下语法：

<a href='mailto:name@domain.com?Subject=SubjTxt&Body=Bod_Txt&Attachment=""C:\file.txt"" '>

处理此问题的更好方法是使用System.Net.Mail.Attachment在服务器上发送邮件。

    public static void CreateMessageWithAttachment(string server)
    {
        // Specify the file to be attached and sent.
        // This example assumes that a file named Data.xls exists in the
        // current working directory.
        string file = "data.xls";
        // Create a message and set up the recipients.
        MailMessage message = new MailMessage(
           "jane@contoso.com",
           "ben@contoso.com",
           "Quarterly data report.",
           "See the attached spreadsheet.");

        // Create  the file attachment for this e-mail message.
        Attachment data = new Attachment(file, MediaTypeNames.Application.Octet);
        // Add time stamp information for the file.
        ContentDisposition disposition = data.ContentDisposition;
        disposition.CreationDate = System.IO.File.GetCreationTime(file);
        disposition.ModificationDate = System.IO.File.GetLastWriteTime(file);
        disposition.ReadDate = System.IO.File.GetLastAccessTime(file);
        // Add the file attachment to this e-mail message.
        message.Attachments.Add(data);

        //Send the message.
        SmtpClient client = new SmtpClient(server);
        // Add credentials if the SMTP server requires them.
        client.Credentials = CredentialCache.DefaultNetworkCredentials;

        try {
          client.Send(message);
        }
        catch (Exception ex) {
          Console.WriteLine("Exception caught in CreateMessageWithAttachment(): {0}", 
                ex.ToString() );              
        }
        data.Dispose();
    }
