c# - System.Net.MailMessage を OpenPop.Mime.Message に変換します

Question

どのように改宗できますか

System.Net.MailMessage

に

OpenPop.Mime.Message

OpenPop.Mime.Message の新しいメッセージを作成します。まず、以下のコードを使用して MailMessage の RawMessage を抽出し、それを OpenPop.Mime.Message のコンストラクターに送信してメッセージのインスタンスを作成します。ただし、電子メールにペルシャ語のコンテンツが含まれている場合、たとえば、送信者の表示名はペルシア語です。 ("مسعود بگرامی"), 変換後の送信者は "??????????" に変更されます`

    private static readonly MethodInfo CloseMethod = MailWriter.GetMethod("Close", Flags);
    private static readonly MethodInfo SendMethod = typeof(MailMessage).GetMethod("Send", Flags);

        var mailWriter = MailWriterConstructor.Invoke(new object[] { result });
        SendMethod.Invoke(self, Flags, null, IsRunningInDotNetFourPointFive ? new[] { mailWriter, true, true } : new[] { mailWriter, true }, null);

        return null;

        //result = new MemoryStream(result);
        //result = new MemoryStream(Encoding.UTF8.GetBytes(result.ToArray().ToString()));
