C#使用XML序列化操作菜單的方法

更新時(shí)間：2014年12月19日 09:37:43 投稿：shichen2014

這篇文章主要介紹了C#使用XML序列化操作菜單的方法,是基于上一篇遞歸讀取XML菜單數(shù)據(jù)的改進(jìn)方法,具有一定的參考借鑒價(jià)值,需要的朋友可以參考下

本文實(shí)例講述了C#使用XML序列化操作菜單的方法。分享給大家供大家參考。具體分析如下：

之前的一篇文章《C#遞歸讀取XML菜單數(shù)據(jù)的方法》沒(méi)使用XML序列化來(lái)操作菜單，而且發(fā)現(xiàn)那還有一個(gè)問(wèn)題，就是在XML菜單的某個(gè)菜單節(jié)點(diǎn)前加上一些注釋代碼的就不能讀取，現(xiàn)在使用XML序列化后可以很方便的讀取，故在此寫一寫。

XML菜單的節(jié)點(diǎn)代碼如下：

復(fù)制代碼代碼如下:

<?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管理系統(tǒng)">

        <Modules>

          <Module ID="OA_System" Text="系統(tǒng)管理">

            <Menus>

         　　　<Menu ID="OA_System_UserManager" Text="人員管理" 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="登錄日志" 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="目標(biāo)管理">

            <Menus>

              <Menu ID="OA_TargetManage_TargetSetup" Text="目標(biāo)設(shè)定" URL="OA/TargetManage/TargetSetupList.aspx">

              </Menu>

            </Menus>

          </Module>

        </Modules>

      </Application>

　　　　<Applications>

</ZCSoft.Net>

這里面有一個(gè)節(jié)點(diǎn)：Applications（應(yīng)用程序節(jié)點(diǎn)），里面可以放多個(gè)Application，而每個(gè)Application節(jié)點(diǎn)里面只包含一個(gè)Modules（模塊節(jié)點(diǎn)），Modules有多個(gè)Module，每個(gè)Module又只有一個(gè)Menus（菜單節(jié)點(diǎn)），而Menus里有多個(gè)Menu。而每個(gè)節(jié)點(diǎn)都有兩個(gè)公共的屬性：ID和Text。

故這里寫一個(gè)公共的屬性類：BaseAttribute，前面記得加上序列化標(biāo)識(shí)Serializable，代碼如下：

復(fù)制代碼代碼如下:

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

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

每個(gè)節(jié)點(diǎn)都有兩個(gè)類，一個(gè)是列表，一個(gè)是實(shí)體，實(shí)體類需繼承公共的類，如下：

復(fù)制代碼代碼如下:

[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>
    /// 菜單類
    /// </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; }
    }

下面幾個(gè)類是用于操作XML的，代碼如下：

復(fù)制代碼代碼如下:

[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類
    /// </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;
            }
        }
    }

最后就是一個(gè)序列化操作類，如下：

復(fù)制代碼代碼如下:

/// <summary>

    /// 序列化XML類

    /// </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;

        }

    }

在后臺(tái)可以這樣調(diào)用，這里沒(méi)用遞歸，如下

復(fù)制代碼代碼如下:

private static ZCSoftPlateForm plateForm;

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

plateForm = LoadFoundationXml.PlateFormObject;

//使用操作XML類來(lái)讀取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;//上一節(jié)點(diǎn)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)
      {
   /*
   * 如果該菜單的所屬模塊中的Display屬性設(shè)置為可見(jiàn)true
   * （注意：沒(méi)有設(shè)置則默認(rèn)為可見(jiàn)），則菜單的上級(jí)為Module的ID
   */
   mData.ParentItem = module.ID;
      }
      else
      {
   /*如果該菜單的所屬模塊中的Display屬性設(shè)置為不可見(jiàn)false，
    * 則菜單的上級(jí)為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);
  }
     }
}
    }
}
