    数据实体接口（对应数据表）

using NBear.Common;
namespace Foo.Data
{
[Table("Article")]
public interface IArticle : IEntity
{
[PrimaryKey]
string Id
{
get;
set;
}
string Title
{
get;
set;
}
String Content
{
get;
set;
}
}
} 

    数据实体属性类（NBear 特有）

using NBear.Common;
namespace Foo.Data
{
public class Article
{
public static PropertyItem Content = new PropertyItem("Content");
public static PropertyItem Id = new PropertyItem("Id");
public static PropertyItem Title = new PropertyItem("Title");
}
} 

    数据访问服务接口

using NBear.Common;
using NBear.IoC.Service;
using Foo.Data;
namespace Foo.Service
{
public interface IArticleService : IServiceInterface
{
void CreateArticle(IArticle article);
}
} 

    数据访问服务实现类

using NBear.Common;
using NBear.Data;
using Foo.Data;
namespace Foo.Service
{
public class ArticleService : IArticleService
{
#region IArticleService 成员 
public void CreateArticle(IArticle article)
{
Gateways.Test.Insert<IArticle>(article);
//throw new Exception("The method or operation is not implemented."); 
}
#endregion 
}
} 

    数据访问路由 Gateways 类（NBear 特有）

using NBear.Data;
namespace Foo.Service
{
/// <summary>
/// Init Database access gateways here
/// </summary> 
public abstract class Gateways
{
private Gateways()
{
}
public static Gateway Test = new Gateway(DatabaseType.SqlServer9, "Data Source=127.0.0.1;Initial Catalog=test;User ID=sa;Password=xxxxxx");
}
} 

    单元测试代码

using NUnit.Framework;
using NBear.Common;
using Foo.Data;
using Foo.Service;
namespace Foo.Test
{
[TestFixture]
public class ArticleServiceTest
{
[Test]
public void CreateArticleTest()
{
ArticleService service = new ArticleService();
IArticle article = EntityFactory<IArticle>.CreateObject();
// 不能设置 id 为 int 自增
// 否则会抛出异常
// 『当 IDENTITY_INSERT 设置为 OFF 时，不能为表 'Article' 中的标识列插入显式值。』
// 所以用 GUID 

article.Id = Guid.NewGuid().ToString();
article.Title = "abc";
article.Content = "abcdefg123456";
service.CreateArticle(article);
}
}
}
