在xaf 14 中实现 Tonyyang原文中的action权限

具体实现过程，主要修改了以下几个地方：

第一：角色和用户类中需要修改成SecurityStrategy的方式：

具体代码

MySecurityRole：
using System;using System.Collections.Generic;using System.Linq;using System.Security;using System.Text;using DevExpress.ExpressApp.Security.Strategy;using DevExpress.Xpo;using DevExpress.Persistent.Base;using DevExpress.Persistent.Validation;using System.Collections.ObjectModel;using DevExpress.Persistent.Base.Security;namespace SecurityDemoTest.Module.BusinessObjects{    [DefaultClassOptions]    public class MySecurityRole : SecuritySystemRole    {        public const string DefaultAdministratorsGroupName = "Administrators";        //private List<IPermission> _Permissions = new List<IPermission>();        public MySecurityRole(Session session)            : base(session)        {        }        [Association("ActionDatas-MySecurityRoles")]        public XPCollection<ActionData> ActionPermissions        {            get            {                return GetCollection<ActionData>("ActionPermissions");            }        }    }}

　　MySecurityUser：

using System;using System.Collections.Generic;using System.Linq;//using DevExpress.ExpressApp.Security;using System.Drawing;using System.Security;using DevExpress.ExpressApp.Security.Strategy;using DevExpress.Persistent.Validation;using DevExpress.Xpo;using DevExpress.Persistent.Base;using DevExpress.Persistent.Base.General;using DevExpress.Persistent.Base.Security;using DevExpress.ExpressApp.DC;using System.ComponentModel;//using WinWebSolution.Module;namespace SecurityDemoTest.Module.BusinessObjects{    [XafDisplayName("User"), Persistent, ImageName("BO_User")]    public class MySecurityUser : SecuritySystemUser // SecurityUserWithRolesBase    {        public MySecurityUser(DevExpress.Xpo.Session session)            : base(session)           {            //_Permissions = new List<IPermission>();        }                [Persistent("Color")]        private int _Color;        [NonPersistent]        public Color Color        {            get { return Color.FromArgb(_Color); }            set { SetPropertyValue("Color", ref _Color, value.ToArgb()); }        }        public override void AfterConstruction()        {            base.AfterConstruction();            _Color = Color.White.ToArgb();        }        private string _Description;        public string Description        {            get            {                return _Description;            }            set            {                SetPropertyValue("Description", ref _Description, value);            }        }    }}

　　第二：需要在ViewController中添加如下代码：

        private static bool IsAllowAccessAction(string actionId)        {            MySecurityUser currentUser = SecuritySystem.CurrentUser as MySecurityUser;            Guard.ArgumentNotNull(currentUser, "CurrentUser");            Guard.ArgumentNotNullOrEmpty(actionId, "ActionId");            foreach (MySecurityRole role in currentUser.Roles)            {                foreach (ActionData ap in role.ActionPermissions)                {                    if (ap.ActionId == actionId && ap.Kind == "Custom")                        return true;                }            }            return false;        }
