Are you just looking to read and write data back and forth to an Excel compatible file? If so, a simple textwriter/reader would work, such as:

//Create a new TextWriter Object that will append to an existing file
TextWriter w = new StreamWriter(@"c:\filepath\filename.csv", true);
w.WriteLine(<Field A> + "," + <Field B> + "," + ........);
w.Close();

To read the data, you would just create and use a TextReader object. This is a very simplistic way of doing, and I would actually recommend taking it a setp further by using XML if you need to actually manipulate the data in your program. To just get it into a format for Excel, the above will work, however.
