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();
