在Web Service的web.config页面进行数据库连接配制：
<connectionStrings>
<add name="DBConnection" connectionString="database=B2CShopDB;server=(local);uid=sa;pwd=sa" providerName="System.Data.SqlClient"/>
</connectionStrings>
Name表示该数据库连接的名字；Database表求要连接的SQL数据库的名字；Server=(local)表求数据库为本地计算机连接；uid是连接数据库使用的用户名，pwd表示连接数据库登录的密码。
