获取每个用户的 SpecialFolder.MyDocuments 文件夹

Question

我的机器上正在运行一个 Windows 服务。如何获取每个用户的 MyDocuments 文件夹？

例如：

对于 Windows XP，我必须获取列表：

• C:\Documents and Settings\User1\我的文档
• C:\Documents and Settings\User2\My Documents
• ...

对于 Windows 10，我必须获取列表：

• C:\Users\User1\Documents\

• C:\Users\User2\Documents\

• ...

如何获得这些列表？

我建议使用this solution，然后只枚举文件夹（针对每个用户）。

// getUserProfilesPath() is a method from https://stackoverflow.com/a/41752173/3179310
string path = getUserProfilesPath();
// now use WMIC to get all users on the local machine
SelectQuery query = new SelectQuery("Win32_UserAccount");
ManagementObjectSearcher searcher = new ManagementObjectSearcher(query);
foreach (ManagementObject result in searcher.Get())
{
    // and check if their folder exists
    if(Directory.Exists(Path.Combine(path, result["Name"])))
    {
        // user folder exists so now check if it has Documents folder
        if(DirectoryExists(Path.Combine(path, result["Name"], "Documents")))
        {
            DirectoryInfo userDocuments = new DirectoryInfo(Path.Combine(path, result["Name"], "Documents"));
            // userDocuments is now a directory info of that user's documents folder
        }
    }
}
