Mail body with multiple line body
<p>I'd like to send an email using C# </p>

<pre><code>            SmtpClient client = new SmtpClient(_smtp, int.Parse(_port));
            client.DeliveryMethod = SmtpDeliveryMethod.Network;
            client.EnableSsl = bool.Parse(_enableSsl);
            client.UseDefaultCredentials = false;
            client.Credentials = new NetworkCredential(APIKey, SecretKey);
            MailMessage mail = new MailMessage();
            mail.From = _from;
            mail.To.Add(_to);
            mail.Subject = _subject;
            mail.Body = _body;
            if(Uri.IsWellFormedUriString(url, UriKind.Absolute)) mail.Body += "&lt;br/&gt;" + url + "&lt;br/&gt;" + "Cordialement";
            mail.IsBodyHtml = false;

            client.Send(mail);
</code></pre>

<p>The mail is sent, but its body is received as a single line .</p>

<p>So How can I fix this issue?</p>
