How to check the OS version at runtime, e.g. on Windows or Linux, without using a conditional compilation statement in C#

To check the operating system version at runtime without using conditional compilation statements in C#, you can use the Environment.OSVersion property and the PlatformID enumeration. The Environment.OSVersion property provides information about the current operating system, and the PlatformID enumeration allows you to check the specific platform.

Here's an example of how to check the OS version at runtime:

using System;

public class Program
{
    public static void Main()
    {
        OperatingSystem os = Environment.OSVersion;

        switch (os.Platform)
        {
            case PlatformID.Win32NT:
                Console.WriteLine("Windows");
                // Additional code for Windows
                break;

            case PlatformID.Unix:
                Console.WriteLine("Unix/Linux");
                // Additional code for Unix/Linux
                break;

            case PlatformID.MacOSX:
                Console.WriteLine("macOS");
                // Additional code for macOS
                break;

            default:
                Console.WriteLine("Unknown OS");
                break;
        }

        Console.WriteLine("Version: " + os.Version);
    }
}

The Environment.OSVersion property returns an instance of the OperatingSystem class, which contains the platform information. The Platform property of the OperatingSystem class returns a PlatformID value that represents the specific operating system platform.

In the example above, we use a switch statement to check the PlatformID and determine the operating system. Based on the platform, you can add additional code to handle specific functionalities or behaviors for each OS.

Please note that the Environment.OSVersion property returns general platform information, and it might not always provide detailed OS version information for all operating systems. For more specific and detailed OS version information, you may need to use platform-specific APIs or libraries.
