C＃File.Exist（File_Path）返回false，即使File_Path为true，文件存在并且我有权访问该文件

Question

I'm writing a software which will run on Windows 7. I'm listing installed services, getting service's image path locations and checking if service file exists.(Dll or Exe).

I'm checking file locations with File.Exist(File_Path) . For some files, it returns false even if file path is true , file exists and I have rights to Access that file.

I know that even if that file exists, if the user don't have the rights to Access it File.Exist(File_Path) returns false.

For example, it returns true for the file C:\\Windows\\System32\\appmgmts.dll but it returns false for the file C:\\Windows\\System32\\audiosrv.dll

And when I look user permissions for these 2 files under the Windows explorer, they are exactly same. But File.Exist(File_Path) returns different answers for these files.

I'm running Visual Studio, and Exe file as an Administrator.

Please give me some advices for this strange behavior.

当我在x86配置中执行File.Exists时，我得到的结果是相同的，但是当我64岁时，这两个文件返回true，并且在网上发现SysWOW64中您搜索的File.Exists时，请查看此问题以获取更多信息： 使用File.Exists检查文件是否在64位系统上存在

I fixed a similar issue that occurred while checking files over a mapping that I created with my domain credentials. I was debugging VS as an Administrator. I was able to navigate through Windows Explorer to the file but not with VS.

I solved the problem when I closed VS Admin mode and started it normally back again.
