If you read the performance and benchmark stats on this website, you'll see that the fastest way to read (because reading, writing, and processing are all different) a text file is the following snippet of code:

using (StreamReader sr = File.OpenText(fileName))
{
    string s = String.Empty;
    while ((s = sr.ReadLine()) != null)
    {
        //do your stuff here
    }
}

All up about 9 different methods were bench marked, but that one seem to come out ahead the majority of the time, even out performing the buffered reader as other readers have mentioned.
