订购列表的最简单方法是使用OrderBy

 List<Order> objListOrder = 
    source.OrderBy(order => order.OrderDate).ToList();

如果要按多个列排序，如以下SQL查询。

ORDER BY OrderDate, OrderId

要实现这一点，您可以像下面这样使用ThenBy。

  List<Order> objListOrder = 
    source.OrderBy(order => order.OrderDate).ThenBy(order => order.OrderId).ToList();

以上答案对我来说都不够通用，所以我做了一个：

var someUserInputStringValue = "propertyNameOfObject i.e. 'Quantity' or 'Date'";
var SortedData = DataToBeSorted
                   .OrderBy(m => m.GetType()
                                  .GetProperties()
                                  .First(n => 
                                      n.Name == someUserInputStringValue)
                   .GetValue(m, null))
                 .ToList();

不过，要小心处理海量数据集。这是一个简单的代码，但如果集合是巨大的，并且集合的对象类型包含大量字段，则可能会给您带来麻烦。运行时间为NxM，其中：

N=集合中的元素数

M=对象中的财产数量

罗杰版本的改进版。

GetDynamicSortProperty的问题是只获取属性名称，但如果在GridView中使用NavigationProperties会发生什么？它将发送一个异常，因为它找到null。

例子：

“Employee.Company.Name；”将崩溃。。。因为只允许“Name”作为参数获取其值。

这是一个改进的版本，允许我们按导航财产排序。

public object GetDynamicSortProperty(object item, string propName)
    {
        try
        {                 
            string[] prop = propName.Split('.'); 

            //Use reflection to get order type                   
            int i = 0;                    
            while (i < prop.Count())
            {
                item = item.GetType().GetProperty(prop[i]).GetValue(item, null);
                i++;
            }                     

            return item;
        }
        catch (Exception ex)
        {
            throw ex;
        }


    } 

请让我用@LukeH的一些示例代码来完成答案，因为我已经测试了它，我相信它可能对某些人有用：

public class Order
{
    public string OrderId { get; set; }
    public DateTime OrderDate { get; set; }
    public int Quantity { get; set; }
    public int Total { get; set; }

    public Order(string orderId, DateTime orderDate, int quantity, int total)
    {
        OrderId = orderId;
        OrderDate = orderDate;
        Quantity = quantity;
        Total = total;
    }
}

public void SampleDataAndTest()
{
    List<Order> objListOrder = new List<Order>();

    objListOrder.Add(new Order("tu me paulo ", Convert.ToDateTime("01/06/2016"), 1, 44));
    objListOrder.Add(new Order("ante laudabas", Convert.ToDateTime("02/05/2016"), 2, 55));
    objListOrder.Add(new Order("ad ordinem ", Convert.ToDateTime("03/04/2016"), 5, 66));
    objListOrder.Add(new Order("collocationem ", Convert.ToDateTime("04/03/2016"), 9, 77));
    objListOrder.Add(new Order("que rerum ac ", Convert.ToDateTime("05/02/2016"), 10, 65));
    objListOrder.Add(new Order("locorum ; cuius", Convert.ToDateTime("06/01/2016"), 1, 343));


    Console.WriteLine("Sort the list by date ascending:");
    objListOrder.Sort((x, y) => x.OrderDate.CompareTo(y.OrderDate));

    foreach (Order o in objListOrder)
        Console.WriteLine("OrderId = " + o.OrderId + " OrderDate = " + o.OrderDate.ToString() + " Quantity = " + o.Quantity + " Total = " + o.Total);

    Console.WriteLine("Sort the list by date descending:");
    objListOrder.Sort((x, y) => y.OrderDate.CompareTo(x.OrderDate));
    foreach (Order o in objListOrder)
        Console.WriteLine("OrderId = " + o.OrderId + " OrderDate = " + o.OrderDate.ToString() + " Quantity = " + o.Quantity + " Total = " + o.Total);

    Console.WriteLine("Sort the list by OrderId ascending:");
    objListOrder.Sort((x, y) => x.OrderId.CompareTo(y.OrderId));
    foreach (Order o in objListOrder)
        Console.WriteLine("OrderId = " + o.OrderId + " OrderDate = " + o.OrderDate.ToString() + " Quantity = " + o.Quantity + " Total = " + o.Total);

    //etc ...
}

在没有Linq的情况下，正如你所说：

public class Order : IComparable
{
    public DateTime OrderDate { get; set; }
    public int OrderId { get; set; }

    public int CompareTo(object obj)
    {
        Order orderToCompare = obj as Order;
        if (orderToCompare.OrderDate < OrderDate || orderToCompare.OrderId < OrderId)
        {
            return 1;
        }
        if (orderToCompare.OrderDate > OrderDate || orderToCompare.OrderId > OrderId)
        {
            return -1;
        }

        // The orders are equivalent.
        return 0;
    }
}

然后只需在订单列表中调用.sort（）

假设您有以下代码，在这段代码中，我们有一个Passenger类，其中有几个我们想要排序的财产。

public class Passenger
{
    public string Name { get; }
    public string LastName { get; }
    public string PassportNo { get; }
    public string Nationality { get; }

    public Passenger(string name, string lastName, string passportNo, string nationality)
    {
        this.Name = name;
        this.LastName = lastName;
        this.PassportNo = passportNo;
        this.Nationality = nationality;
    }

    public static int CompareByName(Passenger passenger1, Passenger passenger2)
    {
        return String.Compare(passenger1.Name, passenger2.Name);
    }

    public static int CompareByLastName(Passenger passenger1, Passenger passenger2)
    {
        return String.Compare(passenger1.LastName, passenger2.LastName);
    }

    public static int CompareNationality(Passenger passenger1, Passenger passenger2)
    {
        return String.Compare(passenger1.Nationality, passenger2.Nationality);
    }
}

public class TestPassengerSort
{
    Passenger p1 = new Passenger("Johon", "Floid", "A123456789", "USA");
    Passenger p2 = new Passenger("Jo", "Sina", "A987463215", "UAE");
    Passenger p3 = new Passenger("Ped", "Zoola", "A987855215", "Italy");

    public void SortThem()
    {
        Passenger[] passengers = new Passenger[] { p1, p2, p3 };
        List<Passenger> passengerList = new List<Passenger> { p1, p2, p3 };

        Array.Sort(passengers, Passenger.CompareByName);
        Array.Sort(passengers, Passenger.CompareByLastName);
        Array.Sort(passengers, Passenger.CompareNationality);

        passengerList.Sort(Passenger.CompareByName);
        passengerList.Sort(Passenger.CompareByLastName);
        passengerList.Sort(Passenger.CompareNationality);

    }
}

因此，您可以使用Composition委托实现排序结构。
