我试图来检测,如果该目录存在,但在这种特殊情况下我的目录是一个网络位置。
我用VB.NET的 My.Computer.FileSystem.DirectoryExists(PATH)
和更普遍的 System.IO.Directory.Exists(PATH)
,在这两种情况下,系统的响应是假的。
我查了一下路径存在,我可以在我的电脑文件夹中查看。
如果我调试程序,并观看 My.Computer.FileSystem.Drives
变量,网络位置没有出现在该列表中。
I'm trying to detect if the directory exists, but in this particular situation my directory is a network location.
I used VB.NET's My.Computer.FileSystem.DirectoryExists(PATH)
and the more general System.IO.Directory.Exists(PATH)
, and in both cases, the system response is false.
I checked and the PATH exists, I can view it in MyComputer Folder.
If I debug the program, and watch the My.Computer.FileSystem.Drives
variable, the network location does not appear in that list.
更新:我检查,并在Windows XP中的反应是真实的,但不是在Windows 7
UPDATE: I checked and in Windows XP the Response is True, but not in Windows 7.
UPDATE2:我测试了提出的解决方案,但我仍然有同样的问题,在图像上下面你会看到,我可以访问使用浏览器,但我的程序不能。
该 GetUNCPath
函数返回一个有效的路径(没有错误),但 Directory.Exists
还是老样子返回false。
UPDATE2: I tested both proposed solutions but I still have the same problem, on the image below you will see that I can access using Explorer but my program cannot.
The GetUNCPath
function returns a valid path (no errors), but Directory.Exists
stil returns false.
我也试图与UNC路径\\服务器\图像;同样的结果。
I also tried with the UNC path "\\Server\Images"; same result.
UPDATE3:如果我不能与网络驱动器链接,我怎么能链接到直接UNC路径?我发现,如果我在正常模式下运行VS,它的工作原理,但我的软件必须在管理员模式下运行。那么,有什么办法来检查网络目录管理员的存在?
UPDATE3: If I cannot link with a network drive, how can I link to UNC path directly?. I discovered that if i run VS in normal mode, it works, but my software must run in administrator mode. So, there is any way to check the existence of a network directory as administrator?
如果UAC已开启,映射的网络驱动器只能在它们被映射到会话存在默认:正常或升高。如果映射从资源管理器网络驱动器,然后运行VS作为管理员,驱动器不会在那里。
If UAC is turned on, mapped network drives only exist "by default" in the session they are mapped: Normal or elevated. If you map a network drive from explorer, then run VS as admin, the drive will not be there.
您需要启用MS什么叫挂连接: HKEY_LOCAL_MACHINE \ SOFTWARE \微软\的Windows \ CurrentVersion \政策\系统:EnableLinkedConnections(REG_DWORD)=为0x1
You need to enable what MS calls "linked connections": HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\System: EnableLinkedConnections (REG_DWORD) = 0x1
