、利用System.Web.Configuration类
读取代码：
String strconn = System.Web.Configuration.WebConfigurationManager.ConnectionStrings["AddressBookConnectionString"].ConnectionString;
或
string strconn = System.Configuration.ConfigurationManager.ConnectionStrings["AddressBookConnectionString"].ConnectionString;

web.config中的配置代码：
<connectionStrings>
<add name="AddressBookConnectionString" connectionString="Data Source=PC- 20090911ZYIV;Initial Catalog=addressBook;User ID=sa;Password=sa" providerName="System.Data.SqlClient" />
</connectionStrings>

2、利用System.Configuration类
读取代码：
string strconn = System.Configuration.ConfigurationManager.AppSettings["AddressBookConnectionString"].ToString();

web.config中的配置代码：
<appSettings>
<add key="AddressBookConnectionString" value="Data Source=PC-20090911ZYIV;Initial Catalog=addressBook;User ID=sa;Password=sa"/>
</appSettings>
