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();
