VSTO Outlook加載項：郵編COM對象

Question

我想壓縮收到的電子郵件之前，它被附加到另一封電子郵件。所以我堅持使用zip部分。我試圖壓縮的對象是一個COM對象，不支持序列化。任何可以幫助我進步的想法都是值得歡迎的！

而且到目前爲止的代碼（selObject是COM對象）：

private void Report_Malicious_Email_Click(object sender, RibbonControlEventArgs e) 
{ 
    // selObject este mailul selectat 
    Object selObject = this.Application.ActiveExplorer().Selection[1]; 
    if (selObject is Outlook.MailItem) // de aici incepe logica pentru forward cu atasament! 
    { 
     using (MemoryStream msCompressed = new MemoryStream()) 
     using (GZipStream gZipStream = new GZipStream(msCompressed, CompressionMode.Compress)) 
     using (MemoryStream msDecompressed = new MemoryStream()) 
     { 
      new BinaryFormatter().Serialize(msDecompressed, selObject); 
      byte[] byteArray = msDecompressed.ToArray(); 

      gZipStream.Write(byteArray, 0, byteArray.Length); 
      gZipStream.Close(); 
      msCompressed.ToArray(); 
     } 

     Outlook.MailItem eMail = 
      (Outlook.MailItem)this.Application.CreateItem(Outlook.OlItemType.olMailItem); 
     eMail.Subject = subjectEmail; 
     eMail.To = toEmail; 
     eMail.Body = bodyEmail; 
     eMail.Attachments.Add(selObject); 
     eMail.Send(); 
    } 
} 

Answer 1

保存信息爲MSG文件（MailItem.SaveAs（...，olMsg）），然後壓縮文件。
