MVC基于角色权限控制--用户管理

 用户管理模块包括 新增用户、修改用户、展示用户列表、删除用户、用户角色分配、用户角色删除、用户权限分配

这里只介绍关于权限有关的 用户角色分配、用户角色删除、用户权限分配

新建控制器 UserInfoController继承 BaseController

            //查询所有的角色.
              short delFlag = (short)DeleteEnumType.Normarl;
           var allRoleList= RoleInfoService.LoadEntities(r=>r.DelFlag==delFlag).ToList();
             //查询一下要分配角色的用户以前具有了哪些角色编号。
