Environment.GetFolderPath(...CommonApplicationData) 在 Vista 上仍然返回“C:\Documents and Settings\”

Question

据我了解，您应该使用 Environment.GetFolderPath 方法，以便您拥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，而不是应该的 C:\ProgramData... 有什么想法吗？

    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);
    }

Answer 1

我的安装程序复制了一个在 XP 计算机上生成的 log.txt 文件。我正在查看那个日志文件，认为它是在 Vista 上生成的。一旦我将我的 log4net 配置修复为“Vista 兼容”。 Environment.GetFolderPath 正在返回预期结果。因此，我将关闭这篇文章。

以下 SpecialFolder 路径参考可能有用：
