EF POCO (自定义实体类) 创建过程

     1 建表

CREATE TABLE [dbo].[TEST](
    [v1] [int] IDENTITY(1,1) NOT NULL,[v2] [varbinary](50) NOT NULL,[v3] [datetime] NOT NULL,CONSTRAINT [PK_TEST] PRIMARY KEY CLUSTERED
(
    [v1] ASC
)WITH (PAD_INDEX  = OFF,STATISTICS_norECOmpuTE  = OFF,IGnorE_DUP_KEY = OFF,ALLOW_ROW_LOCKS  = ON,ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]

      2 edmx创建

3 . 建立实体类，和映射对应实体类（本例采用ObjectContext方式）

1.） 实体类     TEST.cs

            实体类的名字一定要和edmx的实体类名字对应

            实体类的属性要与Edmx中属性对应，包括属性是否为空等

namespace WebApplication3
{
    public partial class TEST
    {
        public int v1 { get; set; }
        public string v2 { get; set; }
        public  Nullable<DateTime> v3 { get; set; }
    }

    public partial class TESTEntities : ObjectContext
    {
        public ObjectSet<TEST> TEST
        {
            get { return _test ?? (_test = CreateObjectSet<TEST>("TESTs")); }
        }
        private ObjectSet<TEST> _test;
    }
}




2）. 映射实体类TESTEntities.cs
     对应Webconfig中connectstring的名字          

<add name="TESTEntities" connectionString="Metadata=res://*/test.csdl|res://*/test.ssdl|res://*/test.msl;provider=System.Data.sqlClient;provider connection string="Data Source=JACKIE-PC\sqlSERVER2008;Initial Catalog=TEST;User ID=sa;Password=Fabric2010;MultipleActiveResultSets=True""
 providerName="System.Data.EntityClient" />


namespace WebApplication3

{

    public partial class TESTEntities : ObjectContext

    {

        public const string ConnectionString = "name=TESTEntities";

        public const string ContainerName = "TESTEntities";


        #region Constructors


        public TESTEntities()

            : base(ConnectionString,ContainerName)

        {

        }

        #endregion

    }

}

4. 映射关系完成，我们可以使用自己定义的实体类了，POCO创建完毕

     protected void Page_Load(object sender,EventArgs e)

        {

            using (TESTEntities db = new TESTEntities())

            {

                var ctt = db.TEST.ToList();

                this.gdvTest.DataSource = ctt;

                this.gdvTest.DataBind();

            }

        }
