Read CSV file into LINQ

This article is based on the great book of LINQ in Action. I am learning so much from it and I would like to keep a note of some handy subject from the book while not disturbing any copyright of ther authors. For the full story please buy the book from http://www.manning.com/LINQinAction.

 
using (StreamReader reader = new StreamReader("books.csv"))
{
  var books = 
    from line in reader.Lines()
    where !line.StartsWith("#")
    let parts = line.Split(',')
    select new {
        Title = parts[1],
        Publisher = parts[3],
        Isbn = parts[0]
    };

  // use the books here ...
}
