关于C#中的List<>和WPF中的listview

Question

定义了一个学生类,并且给学生类的各属性赋值, 在ListView中指定列取指定属性的值 应该怎么改;
初学者, 代码实在不会改了
 public zhujiemian()
        {
            InitializeComponent();
            
            List<students> stulist = new List<students>();
            for (int i = 0; i < 3; i++)
            {
            
                students stu = new students();
                stu.Age = i;
                stu.Name = i + "haha";
                stu.Sex = "男的";
               stulist.Add(stu);
            }
           lvkecheng.ItemsSource =  stulist;
        }
       public class students

Answer 1

绑定这个：stulist.Select(x => new { x.某列, x.某另一列, ... }).ToList()

Answer 2

绑定成功以后,这一行的每一列内容都显示Age=0,Name=haha  
下一行的每一列都显示Age=1,Name=haha1   
不能单独设置每一列显示的内容. 每一列都是GridViewColumn,里面没有ItemSource或者Text之类可以绑定的地方啊.
