C#使用XML序列化操作菜单的方法

本文实例讲述了C#使用XML序列化操作菜单的方法。分享给大家供大家参考。具体分析如下：

之前的一篇文章《C#递归读取XML菜单数据的方法》没使用XML序列化来操作菜单，而且发现那还有一个问题，就是在XML菜单的某个菜单节点前加上一些注释代码的就不能读取，现在使用XML序列化后可以很方便的读取，故在此写一写。

XML菜单的节点代码如下：

 
 <?xml version="1.0" encoding="utf-8"?>
 
   <ZCSoft.Net xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
 
    <Applications>
 
       <Application ID ="OA" Text="OA管理系统">
 
         <Modules>
 
           <Module ID="OA_System" Text="系统管理">
 
             <Menus>
 
          　　　<Menu ID="OA_System_UserManager" Text="人员管理" URL="System/UserManager/UserManagerList.aspx"> </Menu>
 
               <Menu ID="OA_System_RoleManager" Text="角色管理" URL="System/RoleManager/RoleManagerList.aspx"></Menu>
 
               <Menu ID="OA_System_LoginLog" Text="登录日志" URL="System/Log/LoginLogList.aspx"></Menu>
 
           　　<Menu ID="OA_System_OperateLog" Text="操作日志" URL="System/Log/OperateLogList.aspx"></Menu>
 
             </Menus>
 
           </Module>
 
           <Module ID="OA_TargetManage" Text="目标管理">
 
             <Menus>
 
               <Menu ID="OA_TargetManage_TargetSetup" Text="目标设定" URL="OA/TargetManage/TargetSetupList.aspx">
 
               </Menu>
 
             </Menus>
 
           </Module>
 
         </Modules>
 
       </Application>
 
 　　　　<Applications>
 
 </ZCSoft.Net>

这里面有一个节点：Applications（应用程序节点），里面可以放多个Application，而每个Application节点里面只包含一个Modules（模块节点），Modules有多个Module，每个Module又只有一个Menus（菜单节点），而Menus里有多个Menu。而每个节点都有两个公共的属性：ID和Text。

故这里写一个公共的属性类：BaseAttribute，前面记得加上序列化标识Serializable，代码如下：

复制代码代码如下:

[Serializable]
    public class BaseAttribute
    {
        [XmlAttribute(AttributeName = "ID")]
        public string ID { get; set; }

        [XmlAttribute(AttributeName = "Text")]
        public string Text { get; set; }
    }

每个节点都有两个类，一个是列表，一个是实体，实体类需继承公共的类，如下：

复制代码代码如下:

[Serializable]
    public class ApplicationList
    {
        public ApplicationList()
        {
            this.Applications = new List<Application>();
        }
        [XmlElement(ElementName = "Application")]
        public List<Application> Applications { get; set; }
    }

[Serializable]
    public class Application : BaseAttribute
    {
        public Application()
        {
            this.Modules = new ModuleList();
        }
        [XmlElement(ElementName = "Modules")]
        public ModuleList Modules { get; set; }

        [XmlAttribute(AttributeName = "URL")]
        public string URL { get; set; }
    }

[Serializable]
    public class ModuleList
    {
        public ModuleList()
        {
            this.modules = new List<Module>();
        }
        [XmlElement(ElementName = "Module")]
        public List<Module> modules { get; set; }
    }

[Serializable]
    public class Module : BaseAttribute
    {
        public Module()
        {
            this.Display = "True";
            this.Menus = new MenuList();
        }
        [XmlElement(ElementName = "Menus")]
        public MenuList Menus { get; set; }

[XmlAttribute(AttributeName = "Display")]
public string Display { get; set; }

        [XmlAttribute(AttributeName = "URL")]
        public string URL { get; set; }
    }

[Serializable]
    public class MenuList
    {
        public MenuList()
        {
            this.Menus = new List<Menu>();
        }
        [XmlElement(ElementName = "Menu")]
        public List<Menu> Menus { get; set; }
    }

/// <summary>
    /// 菜单类
    /// </summary>
    [Serializable]
    public class Menu : BaseAttribute
    {
        public Menu()
        {
            this.Securityable = false;
            this.Popup = false;
        }

[XmlAttribute(AttributeName = "Popup")]
public bool Popup { get; set; }

[XmlAttribute(AttributeName = "Securityable")]
public bool Securityable { get; set; }

        [XmlAttribute(AttributeName = "URL")]
        public string URL { get; set; }
    }

下面几个类是用于操作XML的，代码如下：

复制代码代码如下:

[Serializable,XmlRoot("ZCSoft.Net")]
    public class ZCSoftPlateForm
    {
        public ZCSoftPlateForm()
        {
            this.Applications = new ApplicationList();
        }
        [XmlElement(ElementName = "Applications")]
        public ApplicationList Applications { get; set; }
    }

/// <summary>
    /// 操作XML类
    /// </summary>
    public class LoadFoundationXml
    {
        private static ZCSoftPlateForm _FoundationObject;
        static LoadFoundationXml()
        {
            if (_FoundationObject == null)
            {
                string path = AppDomain.CurrentDomain.BaseDirectory + "Foundation.xml";
                if (File.Exists(path))
                {
                    _FoundationObject = Serialization.ToObject<ZCSoftPlateForm>(path);
                }
            }
        }
        private LoadFoundationXml()
        {
        }

        public static ZCSoftPlateForm PlateFormObject
        {
            get
            {
                return _FoundationObject;
            }
        }
    }

最后就是一个序列化操作类，如下：

复制代码代码如下:

 
 /// <summary>
 
     /// 序列化XML类
 
     /// </summary>
 
     public class Serialization
 
     {
 
         public static T ToObject<T>(string xmlFile)
 
         {
 
             FileStream stream = null;
 
             T local = Activator.CreateInstance<T>();
 
             try
 
             {
 
                 XmlSerializer serializer = new XmlSerializer(typeof(T));
 
                 stream = new FileStream(xmlFile, FileMode.Open, FileAccess.Read, FileShare.Read);
 
                 local = (T)serializer.Deserialize(stream);
 
                 stream.Close();
 
             }
 
             catch
 
             {
 
                 while (stream != null)
 
                 {
 
                     stream.Close();
 
                     break;
 
                 }
 
                 throw new Exception("Xml deserialization failed!");
 
             }
 
             return local;
 
         }
 
     }

在后台可以这样调用，这里没用递归，如下

复制代码代码如下:

private static ZCSoftPlateForm plateForm;

List<MenuTreeData> list = new List<MenuTreeData>();

plateForm = LoadFoundationXml.PlateFormObject;

//使用操作XML类来读取XML
var appList = plateForm.Applications.Applications;
foreach (var application in appList)
{
    var appData = new MenuTreeData();
    appData.ItemId = 0;
    appData.TemplateId = 0;
    appData.ItemCode = application.ID;
    appData.ItemName = application.Text;
    appData.ItemType = "Folder";
    appData.ItemOrder = 0;
    appData.Visible = true;
    appData.ItemUrl = null;
    appData.ParentItem = null;
    appData.ApplicationCode = application.ID;
    appData.ApplicationName = application.Text;
    appData.ModuleCode = null;
    appData.ModuleName = null;
    appData.Securityable = false;
    appData.Popup = false;
    list.Add(appData);

    if (application.Modules!=null)
    {
foreach (var module in application.Modules.modules)
{
     bool display = module.Display.ToLower() == "true" ? true : false;
     string parentItem = null;//上一节点ID
     var modData = new MenuTreeData();
     modData.ItemId = 0;
     modData.TemplateId = 0;
     modData.ItemCode = module.ID;
     modData.ItemName = module.Text;
     modData.ItemType = "Folder";
     modData.ItemOrder = 0;
     modData.Visible = display;
     modData.ItemUrl = null;
     if (display)
     {
  parentItem = application.ID;
     }

     modData.ParentItem = parentItem;
     modData.ApplicationCode = application.ID;
     modData.ApplicationName = application.Text;
     modData.ModuleCode = module.ID;
     modData.ModuleName = module.Text;
     modData.Securityable = false;
     modData.Popup = false;
     list.Add(modData);

     if (module.Menus!=null)
     {
  foreach (var menu in module.Menus.Menus)
  {
      var mData = new MenuTreeData();
      mData.ItemId = 0;
      mData.TemplateId = 0;
      mData.ItemCode = menu.ID;
      mData.ItemName = menu.Text;
      mData.ItemType = "Menu";
      mData.ItemOrder = 0;
      mData.Visible = true;
      mData.ItemUrl = menu.URL;

      if (display)
      {
   /*
   * 如果该菜单的所属模块中的Display属性设置为可见true
   * （注意：没有设置则默认为可见），则菜单的上级为Module的ID
   */
   mData.ParentItem = module.ID;
      }
      else
      {
   /*如果该菜单的所属模块中的Display属性设置为不可见false，
    * 则菜单的上级为Application的ID
    */
   mData.ParentItem = application.ID;
      }
      mData.ApplicationCode = application.ID;
      mData.ApplicationName = application.Text;
      mData.ModuleCode = module.ID;
      mData.ModuleName = module.Text;
      mData.Securityable = false;
      mData.Popup = false;
      list.Add(mData);
  }
     }
}
    }
}
