Reading data from a text from a text file is easy, once you know what’s happening:

using (var file = new StreamReader(filePath))
{
    ((line = file.ReadLine()) != null)
    {
        //Do stuff here
    }
}

What we’re doing is getting a memory stream of the file, and reading a line of text as defined by MSDN:

A line is defined as a sequence of characters followed by a line feed (“\n”) or a carriage return immediately followed by a line feed (“\r\n”). The string that is returned does not contain the terminating carriage return or line feed. The returned value is a null reference (Nothing in Visual Basic) if the end of the input stream is reached.

This is the easiest way, but not the safest. If the .ReadLine() method throws an OutOfMemoryException (can’t create a buffer for the return string), you loose your place in the stream, and need to re-initialise it (could be a problem in large files with no \n or \r\n chars). You can solve it by pre-allocating a char buffer and populating it with the .Read() method, but then you have to parse for EOL yourself. Ahh well, I’ll maybe get round to it next week.
