委托拉姆达表达式 麻烦看下这段代码什么意思

_order是实体类的实例

 int or_id = Create(_order, (obj) =>
                    {
                        _order.Member = _Member;
                        _order.Or_number = DateTime.Now.ToString("yyyyMMddHHmmssffff");
                        _order.Or_payPrice = 0;
                        _order.Or_buyerName = _Member.M_realName;
                        _order.Or_buyerName = address[0];
                        _order.Or_buyerTel = address[1];
                        _order.Or_buyerAddress = address[2];
                    });

Create方法接收两个参数，具体代码就是读取参数属性值
