用自定义的节来扩展web.config和machine.config配置文件的结构
webconfig:
<?xml version="1.0"?><!-- 有关如何配置 ASP.NET 应用程序的详细信息，请访问 http://go.microsoft.com/fwlink/?LinkId=169433 --><configuration><configSections><section name="RemotingObject" type="RemotingObject"/></configSections><system.web><compilation debug="true" targetFramework="4.0"/></system.web><RemotingObject available="true" pollTimeout="00:01:00" location="tcp://OrderComputer:8010/OrderService"/></configuration>
获取自定义节点 内容：
//打开配置文件 Configuration config = WebConfigurationManager.OpenWebConfiguration("~/"); //获取配置节对象 RemotingObject custSection = (RemotingObject)config.GetSection("RemotingObject"); //显示配置节信息 lblInfo.Text += "获取自定义配置节的信息...<br />" + "<b>位置:</b> " + custSection.Location + "<br /><b>是否可用:</b> " + custSection.Available.ToString() + "<br /><b>超时时间:</b> " + custSection.PollTimeout.ToString() + "<br /><br />";
