写过一段时间的DOTNET程序和ROR程序后，受ROR的ActiveRecord框架启发，故此写了DOTNET版本的活动记录框架。具有CRUD、事务、验证器、支持多数据库连接。

先介绍简单的CRUD操作。

建立表结构：

create table products(
id int primary key identity,
name varchar(50),
shape varchar(50),
amount int,
remark varchar(200)
)

然后定义类：

	using EtNet.ActiveRecord;

	[Table("products")]
	public class Product : ActiveRecordBase
	{
		public Product()
		{
			//
			// TODO: 在此处添加构造函数逻辑
			//
		}

		[PrimaryKey]
		public int id
		{
			get {return _id;}
			set {_id = value;}
		}
		[Field]
		public string name
		{
			get {return _name;}
			set {_name = value;}
		}
		[Field]
		public string shape
		{
			get {return _shape;}
			set {_shape = value;}
		}
		[Field]
		public int amount
		{
			get {return _amount;}
			set {_amount = value;}
		}
		[Field]
		public string remark
		{
			get {return _remark;}
			set {_remark = value;}
		}

		private int _id;
		private string _name;
		private string _shape;
		private int _amount;
		private string _remark;
	}

1、增加记录

			Product p = new Product();
			p.name = "电脑";
			p.shape = "PII";
			p.amount = 30;
			p.Create();

2、修改记录

			 Product p = (Product)Product.Find(typeof(Product),1);
			p.shape = "PIII";
			p.amount = 23;
			p.remark = "备用";
			p.Update();

3、删除记录

			Product p = (Product)Product.Find(typeof(Product),1);
			p.Destroy();

4、查询记录

			Product p = (Product)Product.Find(typeof(Product),1);
			Console.WriteLine(p.id);
			Console.WriteLine(p.name);
			Console.WriteLine(p.shape);
			Console.WriteLine(p.amount);

其他的功能操作以后再介绍。
