ie in Random Order, How can I do this Random sorting in List, One thing I can do is to find index of each item and change its index/position,but it will be a hectic. The List items are fixed and are not dynamic.

If yes, please look at: http://stackoverflow.com/a/25106237/2160375. There is an extension method for array, very easy to change it to accept `IList`. — , Aug 05 '14 at 10:02
No, I have a sorted List and I want to change orders of each item randomly, the new order will be fixed — Syed Salman Raza Zaidi, Aug 05 '14 at 10:04
Will your second order be the one for every time? Or will it be different after a page refresh? — Giannis Paraskevopoulos, Aug 05 '14 at 10:05
"I want to change orders of each item randomly, the new order will be fixed". I don't think my english is perfect, but this sentence IMHO has no sense. Or first or second option :) — , Aug 05 '14 at 10:05

you can use Guid.NewGuid().ToString() to randomly sort the order, eg.

var lstResult = yourList.OrderBy(x => Guid.NewGuid().ToString()).ToList();
