Getting the path of the home directory in C#?
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. c:\documents and settings\user
under XP, c:\users\user
under Vista, and /home/user
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:
string homePath = (Environment.OSVersion.Platform == PlatformID.Unix ||
Environment.OSVersion.Platform == PlatformID.MacOSX)
? Environment.GetEnvironmentVariable("HOME")
: Environment.ExpandEnvironmentVariables("%HOMEDRIVE%%HOMEPATH%");
You are looking for Environment.SpecialFolder.UserProfile
which refers to C:\Users\myname
on Windows and /home/myname
on Unix/Linux:
Environment.GetFolderPath(Environment.SpecialFolder.UserProfile)
Note that Environment.SpecialFolder.Personal
is My Documents (or Documents in win7 and above), but same as home directory on Unix/Linux.
Environment.SpecialFolder.Personal
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 %HOMEDRIVE%%HOMEPATH%
. 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 $HOME
on Unix and OSX and %HOMEDRIVE%%HOMEPATH%
on Windows.
I believe what you are looking for is:
System.Environment.GetFolderPath(System.Environment.SpecialFolder.Personal)
For reference, it is infact contained in mscorlib
.
In DotNetCore 1.1 System.Environment.SpecialFolder
does not exist. It might exist in 2.0-beta. Until then, to do this you can use the following:
var envHome = RuntimeInformation.IsOSPlatform(OSPlatform.Windows) ? "HOMEPATH" : "HOME";
var home = Environment.GetEnvironmentVariable(envHome);`
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.
