  7.   
  8. namespace Adding_List_EntityFramework  
  9. {  
  10.     public partial class WebForm1 : System.Web.UI.Page  
  11.     {  
  12.         protected void Page_Load(object sender, EventArgs e)  
  13.         {  
  14.   
  15.         }  
  16.   
  17.         protected void Button1_Click(object sender, EventArgs e)  
  18.         {  
  19.             EmployeeDBEntities context = new EmployeeDBEntities();  
  20.             List<Employee> employees = new List<Employee>()  
  21.             {  
  22.                 new Employee{FirstName="Andy", LastName="Jones"},  
  23.                 new Employee{FirstName="Steve", LastName="Robes"},  
  24.                 new Employee{FirstName="Dave", LastName="Robe"},  
  25.             };  
  26.   
  27.             foreach (Employee employee in employees)  
  28.             {  
  29.                 context.Employees.Add(employee);  
  30.             }  
  31.   
  32.             context.SaveChanges();
