从邮件服务器下载电子邮件并使用C＃获取正确的邮件正文

Question

POP3 objPOP3 = new POP3(server.ToString(),Email.ToString(),password.ToString());
objPOP3.Connect();
if (objPOP3.IsAPOPSupported)
{
    objPOP3.SecureLogin();
}
else
{
   objPOP3.Login();
}

objPOP3.QueryServer();
int count = 0;
for (int index = LastDownloadIndex + 1; index <= objPOP3.TotalMailCount; index++)
{
        try
        {
            count = count + 1;
            string filename, name;
            EmailMessage objEmail = objPOP3.GetMessage(index, false);
            DateTime msgtime1 = Convert.ToDateTime(objEmail.Date);
            string msgsubject = objEmail.Subject.ToString();
            string msgbody = objEmail.Body.ToString().Replace("'", "");

我正在使用此编码从邮件服务器下载邮件，但那时候发送电子邮件内容就像这样
