<p class="MsoNormal"><span style="FONT-FAMILY: 宋体">在客户应用程序中使用类</span><span lang="EN-US">ResourceManager</span><span style="FONT-FAMILY: 宋体">的方式与该类在前面的使用方式没有太大的区别。惟一的区别是要使用定制类</span><span lang="EN-US">DatabaseResourceManager</span><span style="FONT-FAMILY: 宋体">代替类</span><span lang="EN-US">ResourceManager</span><span style="FONT-FAMILY: 宋体">。下面的代码说明了如何使用自己的资源管理器。</span></p>
<p class="MsoNormal"><span style="FONT-FAMILY: 宋体">通过把数据库连接字符串传送给构造函数，创建一个新的对象</span><span lang="EN-US">DatabaseResourceManager</span><span style="FONT-FAMILY: 宋体">。接着像以前一样，调用在基类中实现的</span><span lang="EN-US">GetString()</span><span style="FONT-FAMILY: 宋体">方法，给它传送键和一个</span><span lang="EN-US">CultureInfo</span><span style="FONT-FAMILY: 宋体">类型的可选对象，以指定文化。然后，从数据库中获取一个资源值，因为这个资源管理器使用了类</span><span lang="EN-US">DatabaseResourceSet</span><span style="FONT-FAMILY: 宋体">和</span><span lang="EN-US">DatabaseResourceReader</span><span style="FONT-FAMILY: 宋体">。</span></p>
