class Info:IComparable

     {

         public int Id { get; set; }

         public string Name { get; set; }

         public int CompareTo(object obj) {

             int result;

             try

             {

                 Info info = obj as Info;

                 if (this.Id > info.Id)

                 {

                     result = ;

                 }

                 else

                     result = ;

                 return result;

             }

             catch (Exception ex) { throw new Exception(ex.Message); }

         }

     }

调用方式如下，只需要用sort方法就能实现对list进行排序。

 private static void ReadAccordingCompare() {

             List<Info> infoList = new List<Info>();

             infoList.Add(

                 new Info() { Id = , Name = "abc" });

             infoList.Add(new Info() { Id = , Name = "rose" });

             infoList.Add(new Info() { Id = , Name = "woft" });

                infoList.Sort();

             foreach (var item in infoList)

             {

                 Console.WriteLine(item.Id + ":" + item.Name);

             }

         }
