自定义节

1.首先在<configSections>中定义自定义配置节（例如Index、testSection）和对应的自定义配置节处理程序(例如NameValueSectionHandler)

2.然后添加节的内容

<configuration>
  <configSections>
    <sectionGroup name="Rewrite.NET">
      <section name="Index" type="System.Configuration.NameValueSectionHandler" />
      <section name="SimpleSettingsMay1" type="System.Configuration.NameValueSectionHandler" />
      <section name="RegExpRule1" type="System.Configuration.NameValueSectionHandler" />
    </sectionGroup>
    
    <section name="testSection" type="System.Configuration.NameValueSectionHandler" />
  
  </configSections>
  <testSection>
    <add key="RegExpRule1" value="RexExpRule.RegExp,RexExpRule" />
    <add key="SimpleSettingsMay1" value="RulesEngine.SimpleRule,RulesEngine" />
  </testSection>
  <Rewrite.NET>
    <Index>
      <add key="RegExpRule1" value="RexExpRule.RegExp,RexExpRule" />
      <add key="SimpleSettingsMay1" value="RulesEngine.SimpleRule,RulesEngine" />
    </Index>

    <!--the actual settings for the rule set for the section-->
    <SimpleSettingsMay1>
      <add key="/rewrite.net/webform1.aspx?c=f" value="/rewrite.net/finalpage.aspx" />
    </SimpleSettingsMay1>

    <RegExpRule1>
      <add key="^/rewrite.net/corp/(.*)" value="/rewrite.net/about/$1" />
    </RegExpRule1>

  </Rewrite.NET>
。。。
</configuration>

3.在代码中读取

NameValueCollection SectionIndex = (NameValueCollection)ConfigurationManager.GetSection("Rewrite.NET/Index");

NameValueCollection SectionIndex = (NameValueCollection)ConfigurationManager.GetSection("testSection");

自定义配置节的处理程序也可以自定义

1.创建自定义类

public class MyHandler : ConfigurationSection
    {
        [ConfigurationProperty("myAttrib1", DefaultValue = "Clowns", IsRequired = true)]
        [StringValidator(InvalidCharacters = "~!@#$%^&*()[]{}/;‘\"|\\", MinLength = 1, MaxLength = 60)]
        public String MyAttrib1
        {
            get
            { return (String)this["myAttrib1"]; }
            set
            { this["myAttrib1"] = value; }
        }

    }

2.在<configSections>中注册对应关系

  <configSections>
      <section 
        name="myCustomSection" 
        type="MyConfigSectionHandler.MyHandler, MyCustomConfigurationHandler, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" 
        allowLocation="true" 
        allowDefinition="Everywhere"
      />
      <!-- Other <section> and <sectionGroup> elements. -->
  </configSections>

<myCustomSection myAttrib1="Clowns">

3.读取

MyConfigSectionHandler.MyHandler config =
            (MyConfigSectionHandler.MyHandler)System.Configuration.ConfigurationManager.GetSection(
            "myCustomSection");
