Lambda select 动态字段

直接上代码

//测试数据
public static List<User> myList = new List<User>()
        {
            new User(){ID=, Name="部门1",Age=,IsChild=false},
            new User(){ID=,Name="部门3",Age=,IsChild=true},
            new User(){ID=,Name="部门3",Age=,IsChild=false},
            new User(){ID=,Name="部门2",Age=,IsChild=false},
            new User(){ID=,Name="部门3",Age=,IsChild=true},
            new User(){ID=,Name="部门1",Age=,IsChild=true},
            new User(){ID=,Name="部门2",Age=,IsChild=true},
            new User(){ID=,Name="部门3",Age=,IsChild=false},
            new User(){ID=,Name="部门1",Age=,IsChild=true},
            new User(){ID=,Name="部门3",Age=,IsChild=false},
        };

        public static void Main(string[] args)
        {
            var q = Test(x => x.ID > , x=>new User() { ID=x.ID,Name=x.Name}).ToList();

            Console.ReadLine();
        }

//where 条件
//result 结果
        public static IEnumerable<User> Test(Func<User, bool> where,Func<User,User> result)
        {
            var q = myList.Where(where);
            return q.Select(result);

        }

    }

    //假设数据库全字段类型
    public class User
    {
        public int ID { get; set; }
        public string Name { get; set; }
        public int Age { get; set; }
        public bool? IsChild { get; set; }

        public User Clone()
        {
            return (User)this.MemberwiseClone();
        }

    }
