用户未处理Http Exception：无法连接到SQL Server数据库。 [英] Http Exception was unhandled by the user: Unable to connect to SQL server database.

问题描述

Hello Friends，



其实我正在处理个人资料：我已经创建了一个自定义类并在该类中创建了个人资料属性。



然后我在网络配置文件中继承该对象。

Hello Friends,

Actually i am working on profiles: I have created a custom class and created profile properties in that class.

I am then inheriting that object in the web config file.

namespace shop
{
    public class shopping
    {
        private List<CartItem> _Items = new List<CartItem>();

        public List<CartItem> items
        {
            get { return _Items; }
        }


        public class CartItem
        {
            private string _name;
            private decimal _price;
            private string _description;

            public string Name
            {
                get { return _name; }
                set { _name = value; }

            }

            public decimal Price
            {

                get { return _price; }
                set { _price = value; }
            }


            public string Description
            {
                get { return _description; }
                set { _description = value; }
            }

            public CartItem()
            {

            }
            public CartItem(string name, decimal price, string description)
            {
                _name = name;
                _price = price;
                _description = description;
            }
        }



        public shopping()
        {
            //
            // TODO: Add constructor logic here
            //
        }
    }
}

Web配置：代码

Web Config : code

<profile>
        <properties>
            <add name="shopping" type="shop.shopping"/>
        </properties>
    </profile>

页面代码背后：

Page code behind:

void Page_PreRender()
  {

      gv.DataSource = Profile.shopping.items;
      gv.DataBind();

  }

  public void add(object sender, EventArgs e)
  {

      shop.shopping.CartItem cart = new shop.shopping.CartItem(name.Text, decimal.Parse(price.Text),desc2.Text);
      Profile.shopping.items.Add(cart);
  }

- 点击按钮我想要将商品添加到购物车。我怎么能管理它，但主要的是：在呈现页面的那一刻它抛出异常。



- 为什么发生此异常？因为我有我的数据库。它是否与aspnet_regsql工具有关？



请指教，



谢谢和问候，
Rahul

- On button click i want to add items to the shopping cart. How ever i can manage that, but the main thing is: The moment the page is rendered it throws an Exception.

- Why this exception occured? because i have my data base in place. Is it something related to aspnet_regsql tool?

Please advice,

Thanks and Regards,
Rahul
