c# list排序的实现方式

实体类实现IComparable接口，而且必须实现CompareTo方法

实体类定义如下：

 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);
             }
         }
