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《[url=http://www.1sucai.cn/article/58702.htm]C#递归读取XML菜单数据的方法[/url]》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：
[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：
[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：
[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：
/// <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
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);
}
}
}
}
}
使用到的菜单实体类：
/// <summary>
/// 系统菜单
/// </summary>
public class MenuTreeData
{
public int ItemId { get; set; }
public int TemplateId { get; set; }
public string ItemCode { get; set; }
public string ItemName { get; set; }
public string ItemType { get; set; }
public int ItemOrder { get; set; }
public bool Visible { get; set; }
public string ItemUrl { get; set; }
public string ParentItem { get; set; }
public string ApplicationCode { get; set; }
public string ApplicationName { get; set; }
public string ModuleCode { get; set; }
public string ModuleName { get; set; }
public bool Securityable { get; set; }
public bool Popup { get; set; }
}
