Ndo 新版本发布

      这个版本的Ndo对视图的支持增强了，并且增强对实体类的单表映射，下个版本将增加对一对多关联关系的支持！
      简单介绍一下，实体类的使用方法：

using System;
using NDO;

namespace NDOShippers
{
    public class EntityShipper:Entity
    {
        
        public EntityShipper():base("Shippers")
        {
        }
        
        public override NDO.Entity NewInstance()
        {
            return new EntityShipper();
        }
        

        public int ShipperID
        {  
            get { return this.settings.GetInt32("ShipperID"); }
            set { this["ShipperID"] = value; }
        }
        public string CompanyName
        {  
            get { return (string)this["CompanyName"]; }
            set { this["CompanyName"] = value; }
        }
        public string Phone
        {  
            get { return (string)this["Phone"]; }
            set { this["Phone"] = value; }
        }
        
        
    }
}

Shipper 类的CRUD操作代码如下：

INDOManager nm = NDOManager.Instance;
            EntityShipper shipper = new EntityShipper();
            shipper.CompanyName = "NDO Test";
            shipper.Phone = "(101)  555-6666";

            //insert a shipper record
            nm.Save(shipper);
            Console.WriteLine(shipper.ShipperID);

            EntityShipper shipper2 = nm.Load(typeof(EntityShipper),shipper.ShipperID) as EntityShipper;
            Console.WriteLine(" CompanyName = {0}\t Phone = {1} ",
                (string)shipper2.CompanyName,
                (string)shipper2.Phone);


            //update shipper record
            shipper2.CompanyName = "update ndo test!";
            shipper2.Phone = "(101) 666-8888";
            nm.Save(shipper2);

            EntityShipper shipper3 = nm.Load(typeof(EntityShipper),shipper.ShipperID) as EntityShipper;
            Console.WriteLine(" CompanyName = {0}\t Phone = {1} ",
                (string)shipper3.CompanyName,
                (string)shipper3.Phone);


            //delete a shipper
            nm.Delete(shipper3);

            //check delete result
            EntityShipper shipper4 =  nm.Load(typeof(EntityShipper),shipper.ShipperID) as EntityShipper;
            Console.WriteLine(shipper4.CompanyName == null || shipper4.CompanyName == "");
            Console.ReadLine();
