非常感谢DevTech美国团队的Fenton Webb,他提供的代码是这篇文章中代码的基础。谢谢，Fents！:-)
Fenton最近为一位想用定制的树视图来显示AutoCAD中的图纸集管理器内的信息的ADN会员写了个例子。Fenton的版本用了WPF,我简单化一下,使用了WinForms，但可能后续也会做一个使用WPF的例子。
我对Fenton的代码做了些修改，所以,如果有任何错误，很可能是我的而不是他的。我只是填充了一些类型的数据，但我没有操作这些数据（我不知道是否有任何真正的需要），别人可能需要做进一步的工作来使用这些数据，甚至把代码截取出来。
总之，下面是C＃代码。为使代码运行,将需要增加对acsmcomponents18.tlb（或acsmcomponents17.tlb如果使用AutoCAD 2007-2009年）的参考，以及AcMgd.dll，AcDbMgd.dll和Visual Studio提供的.NET组件。

您将需要添加一个新的UserControl到您的项目中的一个TreeView中,并设置Dock属性为fill(填补)。一定要保持默认名称UserControl1和treeView1。除此之外，没有任何用户界面的工作需要作。
下面是我们运行SSTREE命令和把硬编码的DST导入到SheetSet管理器（用SSM命令显示）进行的比较：
显然你可以多做一些工作，使两个用户界面看起来相同（图标等），但那是更多的关于递归解析SheetSet树的问题，而不是我侧重要介绍的东西。如果您在用其它DST文件时遇到任何问题，一定要出来发表评论。
