built in methods to order a list c#
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();list sorting c#
using System.Linq;
//sorts in acending order {1,2,3,4,5}
myList.Sort();
//Sorts in decending order {5,4,3,2,1}
myList.Sort();
myList.Reverse();
//to sort a custom list of classes you have to
//add this inside of your class
public int CompareTo(MyClass other)//replace MyClass with your class type
{
//replace varInClass to the variable that you would like to compare
return this.totalScore.CompareTo(other.varInClass)
