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>).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 = ;
             Company company = dao.GetCompany(id);

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

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

             dao.InsertCompany(cp);

             //删除
             Company c = new Company();
             c.Id = ;
             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>
