Check out example codes for "c# sort list". It will help you in understanding the concepts better.

Code Example 1

using System.Linq;
//This list contains OrderDate, OrderID, Quantity, Total properties
List<Order> objListOrder = new List<Order>(); 
//How to GetOrderList(objListOrder)?
//Answer:
//- Ascending order
List<Order> SortedList = objListOrder.OrderBy(o=>o.OrderDate).ToList();
//- Descending order
List<Order> SortedList = objListOrder.OrderByDescending(o=>o.OrderDate).ToList();

Code Example 2

var simpleList = new List<ObjectName>();
// Order by a property
list.OrderBy(o => o.PropertyName);
// Order by multiple property
list.OrderBy(o => o.PropertyName).ThenBy(o => o.AnotherProperty);
// Same but descending
list.OrderByDescending(o => o.PropertyName).ThenByDescending(o => o.AnotherProperty);

class Program
{
    static void Main()

        // Call Array.Sort method.
        Array.Sort(colors);
        foreach (string color in colors)
