注意，只能使用于08以上版本。07的显示不出来！实现效果：
c#最适合开发autocad，因为它拥有vb容易的特点，却具有vc++的强大功能。
linkedlist是啥东东？编不过耶！

是一个类似于list的类，有这个命名空间就可以了：system.collections.generic

不起作用
现在编译通过了，但是没有任何作用。我的cad为2009. 分析了一下程序，只定义了一个类。没有找到命令入口。
程序的入口是docstatusbar.mystatusbar();
这段程序在我的程序集里面是通过自动加载来运行的，入口需要你自己添加，你可以在初始化里面运行那个入口，或者自己在那个入口函数那儿定义命令。另外需要打开cad中的图形状态栏选项，请参考下图：
“散步的木头”的回答。在添加命令接口和打开图形状态栏后，能够显示，但不能用鼠标点击按钮来切换文档（没有任何动作），请指教。我是在cad2009中测试的。你说的自动加载是不是相当于netload命令。但还是要有地方调用mystatusbar()才行那！
我电脑上只有cad2008，不好意思，没有在2009上面测试过，应用到2009的话请确认那些事件在2009中能正常使用，不过按autodesk的版本发展计划，应该能通用，但可能两个版本的状态栏有一点微小的区别，也就是两个版本中缺省的状态栏里面的项目数量不一样，看懂我那个代码然后自己相应修改一下就行了，一般需要修改的可能只有一行代码。自动加载是给类定义iextensionapplication接口，然后initialize()方法中调用那个入口，再netload得时候就能自动运行。具体示例可以参考kean的有关文章。 [ ]
好多朋友反映入口的问题，我把完整的文件发上来，不过在2009下使用的问题我现在还解决不了，我电脑上只有2008，没法调试，希望大家见谅！~ 这个为修改以后的代码！
