Recommendations on parsing .eml files in C#

Question

I have a directory of .eml files that contain email conversations. Is there a recommended approach in C# of parsing files of this type?

Answer 1

I posted a sample project to illustrate this answer to Github

The CDO COM DLL is part of Windows/IIS and can be referenced in .net. It will provide accurate parsing and a nice object model. Use it in conjuction with a reference to ADODB.DLL.

public CDO.Message LoadEmlFromFile(String emlFileName)
{
    CDO.Message msg = new CDO.MessageClass();
    ADODB.Stream stream = new ADODB.StreamClass();

    stream.Open(Type.Missing, ADODB.ConnectModeEnum.adModeUnknown, ADODB.StreamOpenOptionsEnum.adOpenStreamUnspecified, String.Empty, String.Empty);
    stream.LoadFromFile(emlFileName);
    stream.Flush();
    msg.DataSource.OpenObject(stream, "_Stream");
    msg.DataSource.Save();

    stream.Close();
    return msg;
}
