DbEntry 简单实现

在着手编码之前首先安装DbEntry DbEntry.Net.4.1.Setup.zip

在建立类库时选择 DbEntryClassLibrary 如图

 DbEntryClassLibrary1 中建立 实体和数据库访问类

如下

 public class Company :DbObjectModel<Company,int>
    {
        public string CompanyName { get; set; }
        public string CompanyID { get; set; }
        public int CompanyType { get; set; }
    }

    public class CompanyDao
    {
        public IList<Company> GetBetweenCompanys()
        {
            IList<Company> BetweenCompanys = DbEntry.From<Company>().Where(o=>o.Id>0).Select();
            return BetweenCompanys;
        }

        public Company GetCompany(int id)
        {
            return DbEntry.GetObject<Company>(id);
        }

        public void UpdateCompany(Company c)
        {
            DbEntry.Update(c);
        }

        public void RemoveCompany(Company c)
        {
            DbEntry.Delete(c);
        }

        public void InsertCompany(Company c)
        {
            DbEntry.Insert(c);
        }
    }

客户端调用

class Program
    {
        static void Main(string[] args)
        {
            CompanyDao dao = new CompanyDao();
            //获取列表
            IList<Company> list = dao.GetBetweenCompanys();

            //查询ID为1的Compny
            int id = 1;
            Company company = dao.GetCompany(id);

            company.CompanyType = 1;//修改Compny
            dao.UpdateCompany(company);

            //添加
            Company cp = new Company();
            cp.CompanyID = "201306271539";
            cp.CompanyName = "InsertTest";
            cp.CompanyType = 0;

            dao.InsertCompany(cp);

            //删除
            Company c = new Company();
            c.Id = 2;
            dao.RemoveCompany(c);
        }
    }

App.config配置

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <section name="Lephone.Settings" type="Lephone.Core.Setting.NameValueSectionHandler, Lephone.Core" />
  </configSections>
  <Lephone.Settings>
    <add key="DataBase" value="@SqlServer2005 :Data Source=127.0.0.1;initial catalog=TestDb;user id=sa;password=123" />
  </Lephone.Settings>
</configuration>
