如果需要对Question实体中的字符串Id进行排序使用Sort函数和委托在解析Id后对Id进行排序价值

    class Question
    {
        public List<QuestionInfo> Questions Info{ get; set; }
    
    }

    class QuestionInfo
    {
        public string Id{ get; set; }
        public string Questions{ get; set; }
    
    }

    var questionnaire = new Question();
     questionnaire.QuestionInfo.Sort((x, y) => int.Parse(x.Id, CultureInfo.CurrentCulture) - int.Parse(y.Id, CultureInfo.CurrentCulture));

//Get data from database, then sort list by staff name:

List<StaffMember> staffList = staffHandler.GetStaffMembers();

var sortedList = from staffmember in staffList
                 orderby staffmember.Name ascending
                 select staffmember;

如果需要对Question实体中的字符串Id进行排序使用Sort函数和委托在解析Id后对Id进行排序价值

    class Question
    {
        public List<QuestionInfo> Questions Info{ get; set; }
    
    }

    class QuestionInfo
    {
        public string Id{ get; set; }
        public string Questions{ get; set; }
    
    }

    var questionnaire = new Question();
     questionnaire.QuestionInfo.Sort((x, y) => int.Parse(x.Id, CultureInfo.CurrentCulture) - int.Parse(y.Id, CultureInfo.CurrentCulture));

使用LiNQ OrderBy

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

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);  

我能想到的最简单的方法是使用Linq：

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