简单吧

Answer 1

应该是Web.config吧
你这样的话就要读取XML文件了

Answer 2

ConfigurationManager.AppSettings["ConnectionString"];

//Web.config文件内容
<?xml version="1.0"?>
<configuration>
   <appSettings>
     <add key="connectionStrings" value="server=(local);uid=sa;pwd=;database=pubs"/>
   </appSettings>
<system.web>
