创建对象并生成结果的3个步骤-Chapter 3 P38

必须完成3个步骤才能创建对象并生成结果：

1 创建对象

namespace LanguageFeatures
{
    public class Product
    {
         
        public int ProductID { get; set; }
        public string Name { get; set; }
        public string Description { get; set; }
        public decimal Price { get; set; }
        public string Category { get; set; }

    }
}

2 设置参数值

  protected string GetMessage()
        {
            //return "Hello.this is a Web Form";
            Product myProduct = new Product();
            myProduct.ProductID = 100;
            myProduct.Name = "Kayak";
            myProduct.Description = "A boat for one person";
            myProduct.Price = 275M;
            myProduct.Category = "Watersports";
            return String.Format("Category:{0}", myProduct.Category );
        }

3返回希望插入到web窗体返回的HTML的值（body部分）

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="LanguageFeatures.Default" %>

<!DOCTYPE html>

<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
    <title>Language Features</title>
</head>
<body>
    <h2>Language Features</h2>
