EmployeesTableAdapter dataset当实体层 和 数据访问层

 
 

 




//EmployeesTableAdapter的怎么 来的？


private EmployeesTableAdapter _employeesAdapter = null;


    protected EmployeesTableAdapter Adapter




    ...{


        get




        ...{


            if (_employeesAdapter == null)


                _employeesAdapter = new EmployeesTableAdapter();




            return _employeesAdapter;


        }


    }




//确实很好 用 


NorthwindTableAdapters.EmployeesTableAdapter ea = new NorthwindTableAdapters.EmployeesTableAdapter();


       this.GridView1.DataSource = ea.GetEmployees();


       this.DataBind();
