In C#, is there any way to have an in-memory file linked as an in-memory SQLite database with System.Data.SQLite?

What I want to do is something along the lines of the following:

using System.Data.SQLite;
using System.IO;

//My SQLite connection
SQLiteConnection myCon;

public void ReadAndOpenDB(string filename)
{
    FileStream fstrm = new FileStream(filename, FileMode.Open);
    byte[] buf = new byte[fstrm.Length];
    fstrm.Read(buf, 0, (int)fstrm.Length);
    MemoryStream mstrm = new MemoryStream(buf);

    //Do some things with the memory stream

    myCon = new SQLiteConnection(/*attach to my memory stream for reading*/);
    myCon.Open();

    //Do necessary DB operations
}

I do not plan on writing to the in-memory DB, but I need to be able to do some things with the file, in memory in my program, before connecting to it.
