下面是一个通用LINQ扩展方法，它不会创建列表的额外副本：

public static void Sort<T,U>(this List<T> list, Func<T, U> expression)
    where U : IComparable<U>
{
    list.Sort((x, y) => expression.Invoke(x).CompareTo(expression.Invoke(y)));
}

要使用它：

myList.Sort(x=> x.myProperty);

我最近构建了另一个接受ICompare＜U＞的插件，以便您可以自定义比较。当我需要进行自然字符串排序时，这很有用：

public static void Sort<T, U>(this List<T> list, Func<T, U> expression, IComparer<U> comparer)
    where U : IComparable<U>
{    
    list.Sort((x, y) => comparer.Compare(expression.Invoke(x), expression.Invoke(y)));
}

使用LINQ

objListOrder = GetOrderList()
                   .OrderBy(o => o.OrderDate)
                   .ToList();

objListOrder = GetOrderList()
                   .OrderBy(o => o.OrderId)
                   .ToList();

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 ...
}

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);  

使用LiNQ OrderBy

List<Order> objListOrder=new List<Order> ();
    objListOrder=GetOrderList().OrderBy(o=>o.orderid).ToList();

//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);
    }
