问题描述

限时送ChatGPT账号..

我有一个信用卡对象列表.信用卡类如下:

I have a list of credit card objects. The credit card class is the following:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace Client
{
    public class CreditCard
    {
        public String A_Number;
        public String A_Name;
        public String A_Type;
        public String A_Owner_Type;
        public String Bank_City;
        public String Bank_State;
        public String Bank_ZIP;
        public String Balance;
        public String C_Username;

        public CreditCard()
        {

        }
    }
}

在另一个类中，我尝试将列表绑定到网格视图，如下所示:

In another class, I am trying to bind the list to a grid view as follows:

protected void Page_Load(object sender, EventArgs e)
        {
            List<CreditCard> list = (List<CreditCard>)Session["list"];
            GridView_List.DataSource = list;
            GridView_List.DataBind();
        }

但是，我收到以下错误:

However, I am receiving the following error:

The data source for GridView with id 'GridView_List' did not have any properties or attributes from which to generate columns.  Ensure that your data source has content.

有什么问题?我检查了列表实际上包含数据，所以我不知道为什么它不起作用?这个问题怎么解决?

What is the problem? I checked that the list actually contains data so I don't know why it won't work? How can this problem be solved?

推荐答案

您必须对 DataBinding 使用公共属性.按如下方式更新您的课程:

You must use public properties for DataBinding. Update your class as follows:

  public class CreditCard
    {
        public String A_Number { get; set; }
        public String A_Name { get; set; }
        public String A_Type { get; set; }
        public String A_Owner_Type { get; set; }
        public String Bank_City { get; set; }
        public String Bank_State { get; set; }
        public String Bank_ZIP { get; set; }
        public String Balance { get; set; }
        public String C_Username { get; set; }

        public CreditCard() { }
    }
