问题 I'm trying to return the .config files that exist in %WINDIR%\System32\inetsrv\config . For this I am using the following code: DirectoryInfo configFolder = new DirectoryInfo(Environment.ExpandEnvironmentVariables("%WINDIR%") + @"\System32\inetsrv\"); FileInfo[] configFiles = configFolder.GetFiles("*.config"); This returns zero objects into configFiles . If I use another folder (say D:\DropBox) is works fine! This code used to work, has something changed?? Also, FileInfo fi = new FileInfo
