我可以转换吗

System.Net.MailMessage

至

OpenPop.Mime.Message

创建 OpenPop.Mime.Message 的新消息。首先，我使用以下代码提取 MailMessage 的 RawMessage，然后将其发送到 OpenPop.Mime.Message 的构造函数以创建消息的实例，但如果电子邮件包含波斯语内容，例如发件人的显示名称是波斯语（“مسعود بهرامی”），转换后发件人更改为“??????????”`

private const BindingFlags Flags = BindingFlags.Instance | BindingFlags.NonPublic;
    private static readonly Type MailWriter = typeof(SmtpClient).Assembly.GetType("System.Net.Mail.MailWriter");
    private static readonly ConstructorInfo MailWriterConstructor = MailWriter.GetConstructor(Flags, null, new[] { typeof(Stream) }, null);
    private static readonly MethodInfo CloseMethod = MailWriter.GetMethod("Close", Flags);
    private static readonly MethodInfo SendMethod = typeof(MailMessage).GetMethod("Send", Flags);

    /// <summary>
    /// A little hack to determine the number of parameters that we
    /// need to pass to the SaveMethod.
    /// </summary>
    private static readonly bool IsRunningInDotNetFourPointFive = SendMethod.GetParameters().Length == 3;

    /// <summary>
    /// The raw contents of this MailMessage as a MemoryStream.
    /// </summary>
    /// <param name="self">The caller.</param>
    /// <returns>A MemoryStream with the raw contents of this MailMessage.</returns>
    public static byte[] RawMessage(this MailMessage self)
    {
        var result = new MemoryStream();

        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()));

        CloseMethod.Invoke(mailWriter, Flags, null, new object[] { }, null);

        //return result;
    }

它看起来不像 System.Net.MailMessage 公开任何将为您进行 byte[] 格式化的方法，因此您必须创建一个 ToByteArray 方法来构造一个字节数组，您可以将其传递给 OpenPop 的构造函数.Mime.Message 以创建消息对象。您可以从以下系统中推断出您需要的数组格式：

将 Gmail API 消息转换为 OpenPop Mime 消息

这并不能完全解决你的问题，但我希望它能给你足够的工作。
