EF添加

1.添加单个模型（CreatRule()是构造模型）（Shop_ActivityRuleProduct是类）

var rule = CreatRule(model);
var ruled = db.Set<Shop_ActivityRuleProduct>().Add(rule);

2.添加多个模型（CreateLadders()是list数组）（Shop_ActivityRuleLadder是类）

var ladders = CreateLadders(model, rule);
var laddereds = db.Set<Shop_ActivityRuleLadder>().AddRange(ladders);
