<p class=MsoNormal><span style='font-family:宋体'>接下来把上述的理论应用到实践中。为了简化起见，使用一个简单的程序集来保存本章中所有定制控件的示例。我们在</span><span
lang=EN-US>Visual Studio .NET</span><span style='font-family:宋体'>中选择创建类型为</span><span
lang=EN-US>Web Control Library</span><span style='font-family:宋体'>的新项目，把该控件库命名为</span><span
lang=EN-US>PCSCustomWebControls</span><span style='font-family:宋体'>，如图</span><span
lang=EN-US>27-5</span><span style='font-family:宋体'>所示。</span></p>
<p align=center><span lang=EN-US><img width=359 height=265

<p align=center style='FTEL:8.15pt'><span style='font-family:宋体'>图</span><span
lang=EN-US> 27-5</span></p>
<p class=MsoNormal><span style='font-family:宋体'>这个项目在</span><span lang=EN-US>C:\ProCSharp\CustomControls</span><span
style='font-family:宋体'>目录中创建，对于在</span><span lang=EN-US>Web</span><span
style='font-family:宋体'>服务器上创建的项目来说，不必像</span><span lang=EN-US>Web</span><span
style='font-family:宋体'>应用程序那样创建该项目，因为它不需要以相同的方式在外部访问。当然，只要记住把生成的程序集复制到</span><span
lang=EN-US>Web</span><span style='font-family:宋体'>应用程序可以找到的地方，就可以在任意位置创建</span><span
lang=EN-US>Web</span><span style='font-family:宋体'>控件库。</span></p>
<p class=MsoNormal><span style='font-family:宋体'>用于简化测试工作的一项技术是，给同一解决方案添加</span><span
lang=EN-US>Web</span><span style='font-family:宋体'>应用程序项目，这个应用程序命名为</span><span
lang=EN-US>PCSCustomWebControlsTestApp</span><span style='font-family:宋体'>。现在，这是使用定制控件库的惟一应用程序，所以为了加快速度，可以在正确的</span><span
lang=EN-US>bin</span><span style='font-family:宋体'>目录下为控件库创建输出程序集</span><span
lang=EN-US>(</span><span style='font-family:宋体'>这表示在每次重新编译时，都不必复制文件了</span><span
lang=EN-US>)</span><span style='font-family:宋体'>。这是通过</span><span lang=EN-US>PCSCustomWebControls</span><span
style='font-family:宋体'>项目的属性页面实现的，如图</span><span lang=EN-US>27-6</span><span
style='font-family:宋体'>所示。</span></p>
<p class=MsoNormal style='line-height:15.0pt'><span style='font-family:宋体'>注意，已经把</span><span
lang=EN-US>Configuration</span><span style='font-family:宋体'>下拉菜单改为</span><span
lang=EN-US>All Configurations</span><span style='font-family:宋体'>，使调试工具和版本发布工具放在同一地方。</span><span
lang=EN-US>Output Path</span><span style='font-family:宋体'>已经改为</span><span
lang=EN-US>C:\Inetpub\wwwroot\PCSCustomWebControlsTestApp\bin</span><span
style='font-family:宋体'>。为了易于调试，还把</span><span lang=EN-US>Debugging</span><span
style='font-family:宋体'>属性页面上的</span><span lang=EN-US>Start URL</span><span
style='font-family:宋体'>选项改为</span><span lang=EN-US>http://localhost/PCSCustom
WebControlsTestApp/WebForm1.aspx</span><span style='font-family:宋体'>，把</span><span
lang=EN-US>Debug Mode</span><span style='font-family:宋体'>改为</span><span
