[PDF.NET] 关于实体类创建表 code first 方法

[刹那的菜鸟]

正常编写实体类

/// <summary>
    /// 产品信息
    /// </summary>
    public class HTE_ProductsSOD:EntityBase
    {

        public HTE_ProductsSOD()
        {
            TableName = "HTE_Products";
            //Schema = "";
            EntityMap = EntityMapType.Table;
            PrimaryKeys.Add("id");
        }
        protected override void SetFieldNames()
        {
            PropertyNames = new string[] { "spec", "weight", "product_id","width","real_price","brand_name",
              "id","productSn","amount","enName","height","cnName","productcategory_name","longth",
          "sale_price","currency","price_time","num"};
        }
        /// <summary>
        /// 规格----
        /// </summary>
        public string spec
        {
            get { return getProperty<System.String>("spec"); }
            set { setProperty("spec", value); }
        }
        /// <summary>
        /// 重量
        /// </summary>
        public decimal weight
        {
            get { return getProperty<System.Decimal>("weight"); }
            set { setProperty("weight", value); }
        }
        /// <summary>
        /// 产品id
        /// </summary>
        public string product_id
        {
            get { return getProperty<System.String>("product_id"); }
            set { setProperty("product_id", value); }
        }

        public decimal width
        {
            get { return getProperty<System.Decimal>("width"); }
            set { setProperty("width", value); }
        }

        public decimal real_price
        {
            get { return getProperty<System.Decimal>("real_price"); }
            set { setProperty("CategoryId", value); }
        }
        /// <summary>
        /// 品牌名称
        /// </summary>
        public string brand_name
        {
            get { return getProperty<System.String>("brand_name"); }
            set { setProperty("brand_name", value); }
        }

        /// <summary>
        /// 对方的唯一标示
        /// </summary>
        public string id { get { return getProperty<System.String>("id"); }
            set { setProperty("id", value); } }
        /// <summary>
        /// 规格---下单的sku 
        /// </summary>
        public string productSn { get { return getProperty<System.String>("productSn"); }
            set { setProperty("productSn", value); } }
        /// <summary>
        /// 库存数量
        /// </summary>
        public int amount { get { return getProperty<System.Int32>("amount"); } 
            set { setProperty("amount", value); } }
        /// <summary>
        /// 英文名称
        /// </summary>
        public string enName
        {
            get { return getProperty<System.String>("enName"); }
            set { setProperty("enName", value); }}

        public decimal height
        {
            get { return getProperty<System.Decimal>("height"); }
            set { setProperty("height", value); }}
        /// <summary>
        /// 中文名称
        /// </summary>
        public string cnName
        {
            get { return getProperty<System.String>("cnName"); }
            set { setProperty("cnName", value); }}
        /// <summary>
        /// 分类名称
        /// </summary>
        public string productcategory_name
        {
            get { return getProperty<System.String>("productcategory_name"); }
            set { setProperty("productcategory_name", value); }}
        /// <summary>
        /// 长度
        /// </summary>
        public decimal longth { get { return getProperty<System.Decimal>("longth"); }
            set { setProperty("longth", value); }
        }
        /// <summary>
        /// 销售价
        /// </summary>
        public decimal sale_price { get { return getProperty<System.Decimal>("sale_price"); } 
            set { setProperty("sale_price", value); } }
        /// <summary>
        /// 货币
        /// </summary>
        public string currency { get { return getProperty<System.String>("currency"); }
            set { setProperty("currency", value); }
        }
        /// <summary>
        /// 价格时间
        /// </summary>
        public string price_time { get { return getProperty<System.String>("price_time"); }
            set { setProperty("price_time", value); } }

        /// <summary>
        /// 存在几个sku 
        /// </summary>
        public int num { get { return getProperty<System.Int32>("num"); }
            set { setProperty("num", value); }
        }
}

dbcontext

    public class MydbContext:DbContext
    {
        public MydbContext()
            : base("SqlServer")
        {
            //
        }
        protected override bool CheckAllTableExists()
        {
            CheckTableExists<HTE_ProductsSOD>();
            return true;
        } 
    }

然后利用DbContext 进行创建表 提示值为空 因为没有下载源码。
