以单声道编译的 C# - 检测操作系统

Question

I am trying to get a C# app running under OSX which is not exactly pain free. To work around some of the issues in the short term, I am thinking of setting up some specific rules when it is running in OSX.

But... What can I use to determine whether the app is running under Windows or OSX?

Answer 1

From the Mono wiki (in my experience, OSX is identified as Unix):

int p = (int) Environment.OSVersion.Platform;
if ((p == 4) || (p == 128)) {
        Console.WriteLine ("Running on Unix");
} else {
        Console.WriteLine ("NOT running on Unix");
}

Or

string msg1 = "This is a Windows operating system.";
string msg2 = "This is a Unix operating system.";
string msg3 = "ERROR: This platform identifier is invalid.";

OperatingSystem os = Environment.OSVersion;
PlatformID     pid = os.Platform;
switch (pid) 
{
    case PlatformID.Win32NT:
    case PlatformID.Win32S:
    case PlatformID.Win32Windows:
    case PlatformID.WinCE:
        Console.WriteLine(msg1);
        break;
    case PlatformID.Unix:
        Console.WriteLine(msg2);
        break;
    default:
        Console.WriteLine(msg3);
        break;
}

I know this is an old question but this worked for me:

//using System.IO
public static string GetOS(){
    if (Directory.Exists("C:\\Windows")) {return "Windows";}
    if (Directory.Exists("/System/Applications/Utilities/Terminal.app")) {return "macOS";}
    return "Linux";
}
