MailMessage Save As EML file (c#+smtpclient)

. NET since 2.0, has greatly improved the function of mail.smtpclient, for the e-mail, can be very comfortable. However, the drawback is not to provide the ability to save the content of the message as a EML file

In fact, SmtpClient and MailMessage have implemented this function, but this function is nonpublic, for the space outside, not visible.

Using Reflector to decompile the System.Net.Mail.SmtpClient you can see:

In the Send (MailMessage) method, a Mailwriter filemailwriter=this is invoked before mail is sent. Getfilemailwriter (this. Pickupdirectorylocation);

We're going to go ahead and locate Getfilemailwriter this way.
