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();c# how to sort a list
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);sorting and ordering numbers in list using C#
