Is there a way to determine the operating system from within a C# program?

[tnolan]

Hi there. I need to know if my code is running in Windows or Mac or Linux. Is there a way to determine the operating system within a C# program?

[saravanan.subramaniam]

using System;

class Sample

{

   public static void Main()

  {

  Console.WriteLine();

  Console.WriteLine("OSVersion: {0}", Environment.OSVersion.ToString());

  }

}

/*
This example produces the following results:
OSVersion: Microsoft Windows NT 5.1.2600.0
*/

The above code works well in Windows, but in RHEL it throws the error "error CS0117: 'Environment' does not contain a definition for 'OSVersion'"

The following code works with any operating system:

using System;

using System.Runtime.InteropServices;

namespace ConsoleApplication

{

    public class Program

    {

        public static void Main(string[] args)

        {

            Console.WriteLine(System.Runtime.InteropServices.RuntimeInformation.OSDescription.ToString());

            Console.WriteLine(System.Runtime.InteropServices.RuntimeInformation.OSArchitecture.ToString());

        }

    }

}
