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);
            
        }
    }
}
