我也想知道在.Net下怎麼瀏覽autocad或proegineer格式的文件？關注!!

如果用Web做。
将文件所在文件夹设置成虚路径，
在数据库中保存这个文件的URL用网页显示文件链接。
点点击可以下载或者直接打开。我觉得用web做简单。

得到文件全名用 microsoft Web 浏览器Com控件打开

但是我必须用form做的呀!有谁能指点下呀!

if you are programming winform, as long as the account under which your app runs has permissions to access those files, why cannot you just use the file path like cnhgj(戏子) suggested?

首先要判断目标机器能不能连接上。
其次要确保有足够的访问权限。
最后就可以通过保存的路径（\\机器名\path）来访问文件

to cnhgj, saucer and kingecg ,那怎么样才能用一个像在web中一个浏览的控件那样来保存这个路径呢?直接写太麻烦了点吧!

本人有一CAD像，不過你要下載一個軟件VoloVEp，然后在系統里引用avviewx.dll，將CAD直接存到數據庫了，不知道對你有沒有用：
