How to Organize Data from a file with given C# classes

There are some cool classes and tricks and short cuts in C#. I know this but I have not worked with C# enough to have them memoried.

One cool trick is this. If you read from a file data that is arranged in a similar line-by-line structure where each line is arranged in columns spaced out by tabs, the data can be read into a kind of class in C# and then you can parse out one column of data by simply doing a "for each" command. Does anyone know off-hand how this is done?

Basically, what I am talking about is this. I understand how to read a file line by line:

            int counter = 0;
            string line;
            System.IO.StreamReader file =
               new System.IO.StreamReader(filename);

            while ((line = file.ReadLine()) != null)
            {
                Console.WriteLine(line);
                counter++;
            }

            file.Close();

Now, how would I go about replacing Console.WriteLine(line); with code that will organize the data automatically into
members of a class provided that the line columns in the input file are seperated by /t (tabs)?
