无法使用System.Linq.Dynamic进行排序

Question

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Linq.Dynamic;

namespace LinqTest
{
    class Program
    {
        static void Main(string[] args)
        {
            List<Sample> sampleData = new List<Sample>() 
            { 
                new Sample{ ID=1, Name="V", Designation="Executive", JoiningDate=DateTime.Now.Date, Salary=45000M },
                new Sample{ ID=2, Name="F", Designation="Executive", JoiningDate=DateTime.Now.Date, Salary=400M },
                new Sample{ ID=3, Name="A", Designation="Boss", JoiningDate=DateTime.Now.Date, Salary=5000M },
                new Sample{ ID=1, Name="D", Designation="Executive", JoiningDate=DateTime.Now.Date, Salary=2500M },
                new Sample{ ID=1, Name="V", Designation="Executive", JoiningDate=DateTime.Now.Date, Salary=45000M }
            };

            IQueryable<Sample> sas = sampleData.AsQueryable<Sample>();
            sas.OrderBy("Name");
        }
    }
}

As you can see above, I am trying to do simple sorting on one of the column using System.Linq.Dynamic library's extension method. But it is not being sorted. When I hover over sas I see the items in its original order. Can someone please tell me why?

Answer 1

The original sas variable remains unordered. You need to save the result of OrderBy :

var myOrderedSas = sas.OrderBy("Name");
