想将treeview做成一个树形菜单，可是不会，救命

Question

C# TreeView SQL示例: 图文说明
http://hi.baidu.com/kjkj911/blog/category/c%23.treeview

Answer 1

你窗体项目成一个dll，数据库表设计的时候：
id  pid  TreeView节点显示名称     窗体名称         程序集名称
1    0      XXXXX                xxxxx   
2    1      XXXXX               单个窗体的名称   生成的Formsdll通过这个表把TreeView填充成一个树形菜单,然后在TreeNode的击事件里面写：
取得当前点击节点的名称和数据库节点显示的名称比较,找出对应的窗体名称值和程序集名称值
通过反射Assembly.Load(程序集名称).CreateInstance(窗体名称)动态创建一个实例，然后将该实例Show就行了

Answer 2

晕,从数据库,到SQL文,再到初始化TREEVIEW都给你做好了,照着拷贝就好了!
"单击树节点调用功能窗口"这个示例中,就没有,全是自己写的方法!
