asp.net-EF事物与存储过程

FK_Equipment_EquipmentClass

这个是sql中的命名规范，外键名称在前面，主键名称在后面

EF事务的代码

  DbTransaction tran = null;
            try
            {
                ne.Connection.Open();
                tran = ne.Connection.BeginTransaction();//对事务的实例化
                //删除数据
                var d = ne.Customers.Where("it.CustomerId='X3SJ2' ").FirstOrDefault();
                ne.DeleteObject(d);
                if (ne.SaveChanges() > 0)
                    tran.Commit();//事务提交

            }
            catch (Exception ex)
            {
                tran.Rollback();//事务回滚，取消上次的操作
                throw ex;
            }
            finally
            {
                if (tran != null && ne.Connection.State != System.Data.ConnectionState.Closed)
                {
                    ne.Connection.Close();
                }
            }

EF使用存储过程

 NorthwindEntities ne = new NorthwindEntities();
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!this.IsPostBack)
                Bind();
        }
        private void Bind()
        {
           var s =  ne.GetCustomerFun("ALFKI");   // GetCustomerFun这个就是存储过程的名称，ALFKI是存储过程需要的值
           //this.GridView1.DataSource = s;
           //this.GridView1.DataBind();
           var list = s.ToList();
           foreach (Customers C in list)
           {
               Response.Write("顾客的地址:" + C.Address);
           }

           var intS = ne.GetCountFun().ToList();//返回的是标量的集合
           Response.Write("数据的总数:" + intS[0].ToString());
        }
