Directory.GetFiles在网站上检索不到文件

[buller]

我这(XP)是正常的，能检索到文件夹下的文件，路径用的绝对路径：

foreach (string files in Directory.GetFiles("E:/Data/Pic/"))

放网站(Windows7)上之后，报错（路径是对的）：

Server Error in '/' Application.

因为你所在的网站上 没有访问权限 你在xp上是用管理员权限所以可以看到

"E:/Data/Pic/"改为“E:\\Data\\Pic”试试，表示路径不能用除法号吧

权限问题 win7上是IIS7了吧
