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?

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

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  
    }  
}  

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?

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]);  
        }  
    }  
}  

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]);
}
}
}
