如何获取当前用户目录？

Using this:

Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData)

I get this output:

我得到这个输出:

"C:\\Documents and Settings\\[USER]\\Application Data"

How can I get the root directory of all users? i.e.:

如何获取所有用户的根目录?即:

"C:\\Documents and Settings\\[USER]\\"

May be this will be a good solution: taking in account whether this is Vista/Win7 or XP and without using environment variables:

可能这将是一个很好的解决方案:考虑这是Vista / Win7还是XP而不使用环境变量:

string path = Directory.GetParent(Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData)).FullName;
if ( Environment.OSVersion.Version.Major >= 6 ) {
    path = Directory.GetParent(path).ToString();
}

Though using the environment variable is much more clear.

虽然使用环境变量更加清晰。

#2

Try:

System.Environment.GetEnvironmentVariable("USERPROFILE");

Edit:

If the version of .NET you are using is 4 or above, you can use the Environment.SpecialFolder enumeration:

如果您使用的.NET版本是4或更高版本,则可以使用Environment.SpecialFolder枚举:

Environment.GetFolderPath(Environment.SpecialFolder.UserProfile);

#3

You can get the UserProfile path with just this:

您可以使用以下方式获取UserProfile路径:

Environment.GetFolderPath(Environment.SpecialFolder.UserProfile);

#4

Also very helpful, while investigating the Environment.SpecialFolder enum. Use LINQPad or create a solution and execute this code:

同样非常有帮助,同时调查Environment.SpecialFolder枚举。使用LINQPad或创建解决方案并执行以下代码:

Enum.GetValues(typeof(Environment.SpecialFolder))
    .Cast<Environment.SpecialFolder>()
    .Select(specialFolder => new
    {
        Name = specialFolder.ToString(),
        Path = Environment.GetFolderPath(specialFolder)
    })
    .OrderBy(item => item.Path.ToLower())

Btw. "fisch" is the first 5 letters of my last name (and is German for "fish"). This is the user name assigned when signing in with a Microsoft Account.

顺便说一句。 “fisch”是我姓氏的前5个字母(德语是“fish”)。这是使用Microsoft帐户登录时分配的用户名。

Environment.GetEnvironmentVariable("userprofile")

Trying to navigate up from a named SpecialFolder is prone for problems. There are plenty of reasons that the folders won't be where you expect them - users can move them on their own, GPO can move them, folder redirection to UNC paths, etc.

尝试从命名的SpecialFolder向上导航很容易出问题。有很多原因导致文件夹不在您期望的位置 - 用户可以自己移动它们,GPO可以移动它们,文件夹重定向到UNC路径等。

Using the environment variable for the userprofile should reflect any of those possible issues.

对userprofile使用环境变量应该反映任何可能的问题。

#6

Try:

System.IO.Directory.GetParent(Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData)).FullName/

#7

Messing around with environment variables or hard-coded parent folder offsets is never a good idea when there is a API to get the info you want, call SHGetSpecialFolderPath(...,CSIDL_PROFILE,...)

当有一个API来获取你想要的信息时,弄乱环境变量或硬编码的父文件夹偏移绝不是一个好主意,调用SHGetSpecialFolderPath(...,CSIDL_PROFILE,...)

#8

$env:USERPROFILE = "C:\\Documents and Settings\\[USER]\\"

#9

you can use the following code:

您可以使用以下代码:

if(Platform.Equals("WinCE"))
{
    m_CurrentPath = Path.GetDirectoryName(Assembly.GetExecutingAssembly().GetName().CodeBase);
}
else if(Platform.Equals("Win32NT"))
{
    m_CurrentPath = Directory.GetCurrentDirectory();
}
