配置文件configSections节点使用实例 。

configSections为自定义节点，增加应用程序可移植性，用于配置文件上传路径，再深入应用可定义工厂方法需要加载创建的类。

1.配置configSections节点

[html] view plain copy

print?

1. <configSections>  
2.     <section name ="MyName" type="LearningConfiguration.NameSectionHandler"/>  
3. </configSections>  
4. <MyName>  
5.     <Add key="lu" name="lulu"></Add>  
6.     <Add key="lu2" name="66"></Add>  
7. </MyName>  

<configSections>    <section name ="MyName" type="LearningConfiguration.NameSectionHandler"/></configSections><MyName>    <Add key="lu" name="lulu"></Add>    <Add key="lu2" name="66"></Add></MyName>

2.定义NameSectionHandler类实现IConfigurationSectionHandler接口

[csharp] view plain copy

print?

1. namespace LearningConfiguration  
2. {  
3.     public class NameSectionHandler : IConfigurationSectionHandler  
4.     {  
5.         #region 隐式实现接口  
6.         public object Create(object parent, object configContext, System.Xml.XmlNode section)  
7.         {  
8.             Dictionary<string, string> names = new Dictionary<string, string>();  
9.             string key = string.Empty;  
10.             string name = string.Empty;  
11.   
12.             //获取配置文件中自定义节点值  
13.             foreach (XmlNode childNode in section.ChildNodes)  
14.             {  
15.                 if (childNode.Attributes["key"] != null)  
16.                 {  
17.                     key = childNode.Attributes["key"].Value;  
18.   
19.                     if (childNode.Attributes["name"] != null)  
20.                     {  
21.                         name = childNode.Attributes["name"].Value;  
22.                     }  
23.                     else  
24.                     {  
25.                         name = string.Empty;  
26.                     }  
27.   
28.                     names.Add(key, name);  
29.                 }  
30.             }  
31.   
32.             return names;  
33.         }  
34.         #endregion  
35.     }  
36. }  

namespace LearningConfiguration{    public class NameSectionHandler : IConfigurationSectionHandler    {        #region 隐式实现接口        public object Create(object parent, object configContext, System.Xml.XmlNode section)        {            Dictionary<string, string> names = new Dictionary<string, string>();            string key = string.Empty;            string name = string.Empty;            //获取配置文件中自定义节点值            foreach (XmlNode childNode in section.ChildNodes)            {                if (childNode.Attributes["key"] != null)                {                    key = childNode.Attributes["key"].Value;                    if (childNode.Attributes["name"] != null)                    {                        name = childNode.Attributes["name"].Value;                    }                    else                    {                        name = string.Empty;                    }                    names.Add(key, name);                }            }            return names;        }        #endregion    }}

 

3.调用

[csharp] view plain copy

print?

1. protected void Page_Load(object sender, EventArgs e)  
2. {  
3.     Dictionary<string, string> names = ConfigurationManager.GetSection("MyName") as Dictionary<string, string>;  
4.     if (names != null)  
5.     {  
6.             //输出：lulu66  
7.         foreach (string key in names.Keys)  
8.         {  
9.             Response.Write(names[key]);  
10.         }  
11.     }  
12. }  

protected void Page_Load(object sender, EventArgs e){    Dictionary<string, string> names = ConfigurationManager.GetSection("MyName") as Dictionary<string, string>;    if (names != null)    {            //输出：lulu66        foreach (string key in names.Keys)        {            Response.Write(names[key]);        }    }}
