鉴于之前写的一篇博文没使用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:
复制代码
1 <?xml version="1.0" encoding="utf-8"?>
2 <ZCSoft.Net xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
3 <Applications>
4 <Application ID ="OA" Text="OA管理系统">
5 <Modules>
6 <Module ID="OA_System" Text="系统管理">
7 <Menus>
8 <Menu ID="OA_System_UserManager" Text="人员管理" URL="System/UserManager/UserManagerList.aspx"> </Menu>
9 <Menu ID="OA_System_RoleManager" Text="角色管理" URL="System/RoleManager/RoleManagerList.aspx"></Menu>
10 <Menu ID="OA_System_LoginLog" Text="登录日志" URL="System/Log/LoginLogList.aspx"></Menu>
11 <Menu ID="OA_System_OperateLog" Text="操作日志" URL="System/Log/OperateLogList.aspx"></Menu>
12 </Menus>
13 </Module>
14
15 <Module ID="OA_TargetManage" Text="目标管理">
16 <Menus>
17 <Menu ID="OA_TargetManage_TargetSetup" Text="目标设定" URL="OA/TargetManage/TargetSetupList.aspx">
18 </Menu>
19 </Menus>
20 </Module>
21 </Modules>
22 </Application>
23 <Applications>
24 </ZCSoft.Net>
复制代码
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
1 [Serializable]
2 public class BaseAttribute
3 {
4 [XmlAttribute(AttributeName = "ID")]
5 public string ID { get; set; }
6
7 [XmlAttribute(AttributeName = "Text")]
8 public string Text { get; set; }
9 }
复制代码
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
1 [Serializable]
2 public class ApplicationList
3 {
4 public ApplicationList()
5 {
6 this.Applications = new List<Application>();
7 }
8 [XmlElement(ElementName = "Application")]
9 public List<Application> Applications { get; set; }
10 }
11
12 [Serializable]
13 public class Application : BaseAttribute
14 {
15 public Application()
16 {
17 this.Modules = new ModuleList();
18 }
19 [XmlElement(ElementName = "Modules")]
20 public ModuleList Modules { get; set; }
21
22 [XmlAttribute(AttributeName = "URL")]
23 public string URL { get; set; }
24 }
25
26
27 [Serializable]
28 public class ModuleList
29 {
30 public ModuleList()
31 {
32 this.modules = new List<Module>();
33 }
34 [XmlElement(ElementName = "Module")]
35 public List<Module> modules { get; set; }
36 }
37
38 [Serializable]
39 public class Module : BaseAttribute
40 {
41 public Module()
42 {
43 this.Display = "True";
44 this.Menus = new MenuList();
45 }
46 [XmlElement(ElementName = "Menus")]
47 public MenuList Menus { get; set; }
48
49 [XmlAttribute(AttributeName = "Display")]
50 public string Display { get; set; }
51
52 [XmlAttribute(AttributeName = "URL")]
53 public string URL { get; set; }
54 }
55
56
57 [Serializable]
58 public class MenuList
59 {
60 public MenuList()
61 {
62 this.Menus = new List<Menu>();
63 }
64 [XmlElement(ElementName = "Menu")]
65 public List<Menu> Menus { get; set; }
66 }
67
68 /// <summary>
69 /// 菜单类
70 /// </summary>
71 [Serializable]
72 public class Menu : BaseAttribute
73 {
74 public Menu()
75 {
76 this.Securityable = false;
77 this.Popup = false;
78 }
79
80 [XmlAttribute(AttributeName = "Popup")]
81 public bool Popup { get; set; }
82
83 [XmlAttribute(AttributeName = "Securityable")]
84 public bool Securityable { get; set; }
85
86 [XmlAttribute(AttributeName = "URL")]
87 public string URL { get; set; }
88 }
复制代码
下面几个类是用于操作XML的,代码如下:
复制代码
1 [Serializable,XmlRoot("ZCSoft.Net")]
2 public class ZCSoftPlateForm
3 {
4 public ZCSoftPlateForm()
5 {
6 this.Applications = new ApplicationList();
7 }
8 [XmlElement(ElementName = "Applications")]
9 public ApplicationList Applications { get; set; }
10 }
11
12 /// <summary>
13 /// 操作XML类
14 /// </summary>
15 public class LoadFoundationXml
16 {
17 private static ZCSoftPlateForm _FoundationObject;
18 static LoadFoundationXml()
19 {
20 if (_FoundationObject == null)
21 {
22 string path = AppDomain.CurrentDomain.BaseDirectory + "Foundation.xml";
23 if (File.Exists(path))
24 {
25 _FoundationObject = Serialization.ToObject<ZCSoftPlateForm>(path);
26 }
27 }
28 }
29 private LoadFoundationXml()
30 {
31 }
32
33 public static ZCSoftPlateForm PlateFormObject
34 {
35 get
36 {
37 return _FoundationObject;
38 }
39 }
40 }
复制代码
最后就是一个序列化操作类,如下:
复制代码
1 /// <summary>
2 /// 序列化XML类
3 /// </summary>
4 public class Serialization
5 {
6 public static T ToObject<T>(string xmlFile)
7 {
8 FileStream stream = null;
9 T local = Activator.CreateInstance<T>();
10 try
11 {
12 XmlSerializer serializer = new XmlSerializer(typeof(T));
13 stream = new FileStream(xmlFile, FileMode.Open, FileAccess.Read, FileShare.Read);
14 local = (T)serializer.Deserialize(stream);
15 stream.Close();
16 }
17 catch
18 {
19 while (stream != null)
20 {
21 stream.Close();
22 break;
23 }
24 throw new Exception("Xml deserialization failed!");
25 }
26 return local;
27 }
28 }
复制代码
在后台可以这样调用,这里没用递归,如下
复制代码
1 private static ZCSoftPlateForm plateForm;
2
3 List<MenuTreeData> list = new List<MenuTreeData>();
4
5 plateForm = LoadFoundationXml.PlateFormObject;
6
7 //使用操作XML类来读取XML
8 var appList = plateForm.Applications.Applications;
9 foreach (var application in appList)
10 {
11 var appData = new MenuTreeData();
12 appData.ItemId = 0;
13 appData.TemplateId = 0;
14 appData.ItemCode = application.ID;
15 appData.ItemName = application.Text;
16 appData.ItemType = "Folder";
17 appData.ItemOrder = 0;
18 appData.Visible = true;
19 appData.ItemUrl = null;
20 appData.ParentItem = null;
21 appData.ApplicationCode = application.ID;
22 appData.ApplicationName = application.Text;
23 appData.ModuleCode = null;
24 appData.ModuleName = null;
25 appData.Securityable = false;
26 appData.Popup = false;
27 list.Add(appData);
28
29 if (application.Modules!=null)
30 {
31 foreach (var module in application.Modules.modules)
32 {
33 bool display = module.Display.ToLower() == "true" ? true : false;
34 string parentItem = null;//上一节点ID
35 var modData = new MenuTreeData();
36 modData.ItemId = 0;
37 modData.TemplateId = 0;
38 modData.ItemCode = module.ID;
39 modData.ItemName = module.Text;
40 modData.ItemType = "Folder";
41 modData.ItemOrder = 0;
42 modData.Visible = display;
43 modData.ItemUrl = null;
44 if (display)
45 {
46 parentItem = application.ID;
47 }
48
49 modData.ParentItem = parentItem;
50 modData.ApplicationCode = application.ID;
51 modData.ApplicationName = application.Text;
52 modData.ModuleCode = module.ID;
53 modData.ModuleName = module.Text;
54 modData.Securityable = false;
55 modData.Popup = false;
56 list.Add(modData);
57
58 if (module.Menus!=null)
59 {
60 foreach (var menu in module.Menus.Menus)
61 {
62 var mData = new MenuTreeData();
63 mData.ItemId = 0;
64 mData.TemplateId = 0;
65 mData.ItemCode = menu.ID;
66 mData.ItemName = menu.Text;
67 mData.ItemType = "Menu";
68 mData.ItemOrder = 0;
69 mData.Visible = true;
70 mData.ItemUrl = menu.URL;
71
72 if (display)
73 {
74 /*
75 * 如果该菜单的所属模块中的Display属性设置为可见true
76 * (注意:没有设置则默认为可见),则菜单的上级为Module的ID
77 */
78 mData.ParentItem = module.ID;
79 }
80 else
81 {
82 /*如果该菜单的所属模块中的Display属性设置为不可见false,
83 * 则菜单的上级为Application的ID
84 */
85 mData.ParentItem = application.ID;
86 }
87 mData.ApplicationCode = application.ID;
88 mData.ApplicationName = application.Text;
89 mData.ModuleCode = module.ID;
90 mData.ModuleName = module.Text;
91 mData.Securityable = false;
92 mData.Popup = false;
93 list.Add(mData);
94 }
95 }
96 }
97 }
98 }
复制代码
使用到的菜单实体类:
复制代码
1 /// <summary>
2 /// 系统菜单
3 /// </summary>
4 public class MenuTreeData
5 {
6 public int ItemId { get; set; }
7
8 public int TemplateId { get; set; }
9
10 public string ItemCode { get; set; }
11
12 public string ItemName { get; set; }
13
14 public string ItemType { get; set; }
15
16 public int ItemOrder { get; set; }
17
18 public bool Visible { get; set; }
19
20 public string ItemUrl { get; set; }
21
22 public string ParentItem { get; set; }
23
24 public string ApplicationCode { get; set; }
25
26 public string ApplicationName { get; set; }
27
28 public string ModuleCode { get; set; }
29
30 public string ModuleName { get; set; }
31
32 public bool Securityable { get; set; }
33
34 public bool Popup { get; set; }
35 }
