Retrieve Email Information from .EML Files

问题:

I have a .eml files. What I want to do is to retrieve the From, To, Subject, Body & attachments(if any) from this .eml file and save to database. I need to do that in C# and without any third party applications.

I searched for some source code, but couldn't find any, except this Is it possible to read .eml files in .net But there is no source code, which is more helpful.
