读取配置文件 某节点值

       public static string GetAppValue(string sKeyName)       {           object oResult = System.Configuration.ConfigurationManager.AppSettings[sKeyName];           if (oResult != null)           {               return oResult.ToString();           }           return "";       }

配置文件如下：

<?xml version="1.0"?><configuration><startup><supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/></startup>  <appSettings>    <add key="SqliteDbPath" value="D:\baiDuYun\bin\Debug\Data\MetroGuide.db"/>    <add key="DefaultStart" value="共富新村"/>    <add key="DefaultEnd" value="广兰路"/>    <add key="RunMode" value="DEV"/> <!--运行模式：DEV,USER -->         <!-- DevEnvironment(1-win7 64bit .net 4; 2-xp 32bit .net4) -->    <add key="DevEnvironment" value="1"/>     </appSettings></configuration>
