You need to be a little more specific than this.

You may read the lines into an array of strings and then shuffle the array indices (and finally write back the array into a file).

Here's some LINQ code that shows how to do this as CPallini suggested:

C#

Random random = new Random();
File.WriteAllLines(fileName, File.ReadAllLines(fileName).OrderBy(s => random.Next()).ToArray());
