菜鸟求答！！ASP.NET

[RichardSzwz]

.NET学习中，
请问下面题：
C#中的.CS:

public class UserInfo
    {
        private int userID; private string username;
        private string email; private DateTime loginDate;
        public int UserID
        {
            get
            {
                return userID;
            }
            set
            {
                userID = value;
            }
        }
        public string Username
        {
            get
            {
                return username;
            }
            set
            {
                username = value;
            }
        }
        public string Email
        {
            get
            {
                return email;
            }
            set
            {
                email = value;
            }
        }
        public DateTime LoginDate
        {
            get
            {
                return loginDate;
            }
            set
            {
                loginDate = value;
            }
        }
    }
    public class Users
    {
        private List<UserInfo> list;
        public Users()
        {
            list = new List<UserInfo>();
            for (int i = 0; i < 10; i++)
            {
                UserInfo ui = new UserInfo();
                ui.UserID = i;
                ui.Username = "MyName #" + (i + 1).ToString();
                ui.Email = ui.Username + "@web.com";
                ui.LoginDate = DateTime.Now;
                list.Add(ui);
            }
        }
        public List<UserInfo> GetUsers()
        {
            return list;
        }
        public void AddUser(UserInfo ui)
        {
            list.Add(ui);
        }
        public void UpdateUser(int userID, UserInfo ui)
        {
            list[userID] = ui;
        }
        public void DeleteUser(UserInfo ui)
        {
            list.Remove(ui);
        }
    }

C#中.ASPX:

<form id="form1" runat="server">
    <div>
    <asp:ListBox ID = "lbUser" runat = "server" DataSourceID = "myObjectDS" DataTextField = "Username" DataValueField = "UserID" 
    Rows = "10" Width = "200px"></asp:ListBox>
    <asp:ObjectDataSource ID = "myObjectDS" runat = "server" DataObjectTypeName = "UserInfo" DeleteMethod = "DeleteUser" InsertMethod = "AddUser" 
    SelectMethod = "GetUsers" TypeName ="Users" UpdateMethod = "UpdateUser" >
    <UpdateParameters>
    <asp:Parameter Name = "userID" Type = "Int32" />
    <asp:Parameter Name = "ui" Type = "Object" />
    </UpdateParameters>
    </asp:ObjectDataSource>
    </div>
    </form>

运行时提示：

DataSourceID = "myObjectDS"
没有这个数据源吧

不帮。

[RichardSzwz]

为什么不帮??

[yifeng133]

哥来告诉你，你需要把UserIfo和Users两个类分开成两个cs文件，这样就应该没问题了
