web.config文件

<appSettings>

   <!--<add key="YZTUrl"value="http://WIN-IAOS1A1SO7O/mapsystemweb/index.aspx" />-->

   <add key="YZTUrl"value="http://win-iaos1a1so7o:8171/MapSystem.Web_SQLSERVER/Default.aspx"/>

   <add key="PageSize"  value="10" />

   <add key="DBLX" value="1"/>

   <add key="XZQ" value="450700"/>

   <!-- 数据库类型 1 SQL Server 2 ORACLE -->

   <add key="Server"value="GTSERVERCP\GTCP2005"/>

</appSettings>

 

读取vs2012中,<appsetings>节点

   DB_META.Value =System.Configuration.ConfigurationManager.AppSettings["DB_META"];

修改<appseting>中的值

  List<XElement> addSets = (from t in xelement.Descendants("add") select t).ToList();

  addSets[10].Attribute("value").Value= txtYZTUrl.Value;
