WPF问题：listview绑定实体类

[yespie]

怎么将下边的实体类绑定到Listview上，谢谢！
我添了几条记录，可是只能在Listvie上显示一条，好郁闷

我是用this.listView.DataContext = cbd;
cdb是下边的实体类

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ClassTestDB
{
    public class ClassDB
    {
        private int _ID;
        private string _User;
        private decimal _Balance;
        List<ClassDB> db = new List<ClassDB>();
        ClassDB cbd;

        public void addList(int a, string b, decimal c)
        {
            cbd = new ClassDB();
            cbd.ID = a;
            cbd.User = b;
            cbd.Balance = c;
        }

        public List<ClassDB> getList()
        {
            return db;
        }

        public int ID
        {
            get
            {
                return this._ID;
            }
            set
            {
                this._ID = value;
            }
        }

        public string User
        {
            get
            {
                return this._User;
            }
            set
            {
                this._User = value;
            }
        }

        public decimal Balance
        {
            get
            {
                return this._Balance;
            }
            set
            {
                this._Balance = value;
            }
        }
    }
}

1 绑定的是需要列表，或
2 你需要实现ToString()函数

public override string ToSting()
{
return String.Format("{0},{1}",ID,User);
}
