Entity Framework 部分应用

Entity Framework执行sql语句：

   Model.UnitOfWork.Current.ExecuteStoreCommand(

        string.Format("update [User] set UserName='{0}',LastModifiedUser='{1}',updatedate='{2}' where UserName='{3}'", model.AlterID, GetLoginUserID,    DateTime.Now,model.BeforeID)

   );

Entity Framework执行sql存储过程：

   int i = Model.UnitOfWork.Current.ExecuteStoreCommand(String.Format("exec proc_ChangeCardID @OldCardID='{0}',@NewCardID='{1}'", model.BeforeID,       model.AlterID));

Entity Framework事务的使用方法：

  Person person = new Person();

  person.ID = IDNumbers.Value;
  person.FullName = FullNames.Value;
  person.BirthDate = Convert.ToDateTime(BirthDates.Value);

        person.EmailAddress = EmailAddresss.Value;

        person.MobileNumber = MobileNumbers.Value;

        person.HomeAddress = HomeAddress.Value;

        if (Sex.Checked == true)

          {

               person.SexName = "男";

          }

        else

          {

               person.SexName = "女";

          }

        person.CreateDate = DateTime.Now;

        PersonCards personcard = new PersonCards();

        personcard.PersonID = IDNumbers.Value;

        personcard.CardID = this.GetCard.ID;

        personcard.TypeID = TypeID.SelectedValue;

        personcard.UpdateDate = DateTime.Now;

        Model.UnitOfWork.Current.PersonCards.AddObject(personcard);

        Model.UnitOfWork.Current.SaveChanges();
