When you say cross-platform way, what other OSs do you need to support? You may need to do some simple OS detection to select the method for finding the home directory if you're running on a non-Windows OS.

<code>Environment.SpecialFolder.Personal</code> doesn't actually return the home folder, it returns the My Documents folder. The safest way to get the home folder on Win32 is to read <code>%HOMEDRIVE%%HOMEPATH%</code>. Reading environment variables is actually very portable to do (across Unix and Windows), so I'm not sure why the poster wanted to not do it.

Edited to add: For crossplatform (Windows/Unix) C#, I'd read <code>$HOME</code> on Unix and OSX and <code>%HOMEDRIVE%%HOMEPATH%</code> on Windows.

The bottom line answer is No. The is no simple System based method in .NET to get the Home directory such that we could expect an implementation in both .NET on Windows and in Mono.

You will need to do some OS detection and branch to OS specific code.

This can be done using <code>GetEnvironmentVariable</code> in <code>System.IO</code>:

<pre><code>public string GetUserHome() {
 var homeDrive = Environment.GetEnvironmentVariable("HOMEDRIVE");
 if (!string.IsNullOrWhiteSpace(homeDrive))
 {
 var homePath = Environment.GetEnvironmentVariable("HOMEPATH");
 if (!string.IsNullOrWhiteSpace(homePath))
 { 
 var fullHomePath = homeDrive + Path.DirectorySeparatorChar + homePath;
 return Path.Combine(fullHomePath, "myFolder");
 }
 else
 {
 throw new Exception("Environment variable error, there is no 'HOMEPATH'");
 }
 }
 else
 {
 throw new Exception("Environment variable error, there is no 'HOMEDRIVE'");
 }
}
</code></pre>

Then it produces under windows: <code>C:\\\\Users\\myusername\\myFolder</code>

Note that if you use 

<pre><code>var fullHomePath = Path.Combine(homeDrive.ToString(), homePath.ToString())
</code></pre>

it fails because it produces: <code>\\Users\\myusername\\myFolder</code>

blocks|key|3314089|text|在DotNetCore+1.1中不存在System.Environment.SpecialFolder。它可能存在于2.0-beta中。在此之前，您可以使用以下命令来执行此操作：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|3314090|var+envHome+=+RuntimeInformation.IsOSPlatform(OSPlatform.Windows)+?+"HOMEPATH"+:+"HOME";

In DotNetCore 1.1 <code>System.Environment.SpecialFolder</code> does not exist. It might exist in 2.0-beta. Until then, to do this you can use the following:

<pre><code>var envHome = RuntimeInformation.IsOSPlatform(OSPlatform.Windows) ? "HOMEPATH" : "HOME";
var home = Environment.GetEnvironmentVariable(envHome);`
</code></pre>

Okay, I've checked Environment.SpecialFolder, but there's nothing in there for this.

I want to get the home directory of the current user in C#. (e.g. <code>c:\documents and settings\user</code> under XP, <code>c:\users\user</code> under Vista, and <code>/home/user</code> under Unix.)

I know I can read enviroment variables to find this out, but I want to do this in a cross-platform way.

Is there any way I can do this with .NET (preferably using mscorlib)?

UPDATE: Okay, this is the code I ended up using:

<pre><code>string homePath = (Environment.OSVersion.Platform == PlatformID.Unix || 
 Environment.OSVersion.Platform == PlatformID.MacOSX)
 ? Environment.GetEnvironmentVariable("HOME")
 : Environment.ExpandEnvironmentVariables("%HOMEDRIVE%%HOMEPATH%");
</code></pre>
