    內部
    <?xml version="1.0"?>
    <configuration>
      <connectionStrings
        <add name="default" connectionString="Data Source=localhost;Initial Catalog=Northwind;Integrated Security=True" providerName="System.Data.SqlClient"/>
      </connectionStrings>
    </configuration>
    外部
    <!-- web.config -->
    <?xml version="1.0"?>
    <configuration>
      <connectionStrings configSource="conn.config" />
    </configuration>

    <!-- conn.config -->
    <connectionStrings>
      <add name="default" connectionString ="data=out;uid=;pid=;"/>
    </connectionStrings>
