Try:

var fileContent = File.ReadAllLines("data.txt");
var separated = fileContent.Select(line => line.Split(' ').ToArray();

You'll end up with array (rows) of values (columns). To access them use:

var row4Col5 = separated[3][4];

Not that you might want to do some boundaries checks, as some lines of your data file don't contain all columns.
