web.config中读取自定义的节点

web.config

<sectionGroup name="CommerceServer">
  <section name="Application" type="System.Configuration.NameValueSectionHandler,system, Version=1.0.3300.0, Culture=neutral, PublicKeyToken=b77a5c561934e089, Custom=null"/>
</sectionGroup>

<CommerceServer>
<Application>
  <add key="box" value="0"/>
  <add key="webvirtual" value="/"/>
</Application>
</CommerceServer>

通过GetConfiguration(application, "CommerceServer/Application");访问

// 得到配置信息
public static void GetConfiguration(NameValueCollection dictionary, string path)
{
 NameValueCollection app = (NameValueCollection)ConfigurationManager.GetSection(path);
 if (app != null)
 {
  NameObjectCollectionBase.KeysCollection keys = app.Keys;
  for (int i = 0; i < keys.Count; i ++)
  {
   dictionary.Add(keys[i], app[keys[i]]);
  } 
 }
}
