Environment.GetFolderPath（… CommonApplicationData）仍然返回Vista上的“C：\ Documents and Settings \”
据我了解，你应该使用Environment.GetFolderPath方法，所以你有独立于操作系统的代码…
Windows XP使用C:\Documents and Settings\ 。 Windows Vista使用C:\ProgramData和C:\Users 。
我在Windows Vista计算机上使用下面的代码，它返回一个C:\Documents and Settings\目录，而不是C:\ProgramData就像它应该…任何想法？
string commonAppData = Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData); try { File.CreateText( Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData) + "\\mycompany\\uid"); log.Debug("Created file successfully"); } catch (Exception ex) { log.Error("Unable to create the uid file: ", ex); }
我的安装程序复制了XP计算机上生成的log.txt文件。 我正在看那个日志文件，认为它是在Vista上生成的。 一旦我将我的log4netconfiguration固定为“Vista兼容”。 Environment.GetFolderPath正在返回预期的结果。 因此，我正在closures这个post。
以下SpecialFolderpath引用可能是有用的：
