如果需要对列表进行排序，则可以使用sort方法，传递Comparison＜T＞委托：

objListOrder.Sort((x, y) => x.OrderDate.CompareTo(y.OrderDate));

如果您希望创建一个新的排序序列而不是就地排序，那么可以使用LINQ的OrderBy方法，如其他答案中所述。

我能想到的最简单的方法是使用Linq：

List<Order> SortedList = objListOrder.OrderBy(o=>o.OrderDate).ToList();

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。

要在.Net 2.0上不使用LINQ的情况下执行此操作，请执行以下操作：

List<Order> objListOrder = GetOrderList();
objListOrder.Sort(
    delegate(Order p1, Order p2)
    {
        return p1.OrderDate.CompareTo(p2.OrderDate);
    }
);

如果你在.Net 3.0上，那么LukeH的答案就是你在追求什么。

要对多个财产进行排序，您仍然可以在委托中进行排序。例如：

orderList.Sort(
    delegate(Order p1, Order p2)
    {
        int compareDate = p1.Date.CompareTo(p2.Date);
        if (compareDate == 0)
        {
            return p2.OrderID.CompareTo(p1.OrderID);
        }
        return compareDate;
    }
);

这将为您提供具有降序ID的升序日期。

然而，我不建议使用委托，因为这意味着很多地方没有代码重用。您应该实现一个IComparer，并将其传递给Sort方法。请参见此处。

public class MyOrderingClass : IComparer<Order>
{
    public int Compare(Order x, Order y)
    {
        int compareDate = x.Date.CompareTo(y.Date);
        if (compareDate == 0)
        {
            return x.OrderID.CompareTo(y.OrderID);
        }
        return compareDate;
    }
}

然后，要使用这个IComparer类，只需实例化它并将其传递给Sort方法：

IComparer<Order> comparer = new MyOrderingClass();
orderList.Sort(comparer);

//用于网格视图的完全通用排序

public List<T> Sort_List<T>(string sortDirection, string sortExpression, List<T> data)
    {

        List<T> data_sorted = new List<T>();

        if (sortDirection == "Ascending")
        {
            data_sorted = (from n in data
                              orderby GetDynamicSortProperty(n, sortExpression) ascending
                              select n).ToList();
        }
        else if (sortDirection == "Descending")
        {
            data_sorted = (from n in data
                              orderby GetDynamicSortProperty(n, sortExpression) descending
                              select n).ToList();

        }

        return data_sorted;

    }

    public object GetDynamicSortProperty(object item, string propName)
    {
        //Use reflection to get order type
        return item.GetType().GetProperty(propName).GetValue(item, null);
    }

基于GenericTypeTea的比较器：我们可以通过添加排序标志来获得更多的灵活性：

public class MyOrderingClass : IComparer<Order> {  
    public int Compare(Order x, Order y) {  
        int compareDate = x.Date.CompareTo(y.Date);  
        if (compareDate == 0) {  
            int compareOrderId = x.OrderID.CompareTo(y.OrderID);  

            if (OrderIdDescending) {  
                compareOrderId = -compareOrderId;  
            }  
            return compareOrderId;  
        }  

        if (DateDescending) {  
            compareDate = -compareDate;  
        }  
        return compareDate;  
    }  

    public bool DateDescending { get; set; }  
    public bool OrderIdDescending { get; set; }  
}  

在此场景中，必须将其显式实例化为MyOrderingClass（而不是IComparer）为了设置其排序财产：

MyOrderingClass comparer = new MyOrderingClass();  
comparer.DateDescending = ...;  
comparer.OrderIdDescending = ...;  
orderList.Sort(comparer);
