如何在TREEVIEW中一次显示C：

[xj5162004]

能显示所有目录、子目录和文件。
再此感谢！

Directory.GetFiles("c:\\");
Directory.GetDirectories("c:\\");
一个是得到C盘根目录下的所有文件
一个是得到所有根目录下的所有文件夹
你把这些添加到treeview中去。

谢谢，我的意思是将C：盘下所有的文件夹和文件，包括文件夹的子文件夹、文件，子文件夹下的子文件夹、文件.....就是一次加入所有的文件夹和文件。

程序將c:所有文件寫到treeview1,如果選擇點擊目錄則將目錄中所有文件列出在treeview2

谢谢，向你学习。

好象在我的机子运行只能显示C：盘下的文件，而不能显示文件夹下的文件？？？
