System.Environment.OSVersion .NET Core 5.0 Framework替换？

Question

System.Environment.OSVersion似乎不是.net core 5.0（dnxcore50）的一部分。

我正在尝试确定用户所在的操作系统，因此当他们将文件保存到文件系统时，我知道使用'/'或'\'

我应该使用什么？

Answer 1

不要自己做检测。使用System.IO.Path。DirectorySeparatorChar。此外，如果您始终使用路径来操作路径，那么您应该获得所需的格式。这也适用于URL。

Answer 2

You can get it back:

using System.Runtime.InteropServices;

namespace System
{


    // [ComVisible(true)]
    // [Serializable]
    public enum PlatformID
    {
        Win32S = 0,
        Win32Windows = 1,
        Win32NT = 2,
        WinCE = 3,
        Unix = 4,
        // Since NET 3.5 SP1 or silverlight
        Xbox = 5,
        MacOSX = 6,
    }


    public class OperatingSystem
    {
        private Architecture m_arch;
        private bool m_isARM;
        private bool m_isX86;
        private bool m_isLinux;
        private bool m_isOSX;
        private bool m_isWindows;
        private PlatformID m_platform;

        public OperatingSystem()
        {
            m_arch = RuntimeInformation.ProcessArchitecture;
            m_isARM = (m_arch == Architecture.Arm || m_arch == Architecture.Arm64);
            m_isX86 = (m_arch == Architecture.X86 || m_arch == Architecture.X64);

            m_isLinux = RuntimeInformation.IsOSPlatform(OSPlatform.Linux);
            m_isOSX = RuntimeInformation.IsOSPlatform(OSPlatform.OSX);
            m_isWindows = RuntimeInformation.IsOSPlatform(OSPlatform.Windows);

            if (m_isLinux || m_isOSX)
                m_platform = PlatformID.Unix;
            else if (m_isWindows)
            {
                m_platform = PlatformID.Win32NT;
            }
            else
                throw new System.PlatformNotSupportedException("Operating system not supported.");
        }

        public PlatformID Platform
        {
            get
            {
                return m_platform;
            }
        }
    }



    public class OldEnvironment
    {

        private static OperatingSystem m_OS;

        static OldEnvironment()
        {
            m_OS = new OperatingSystem();
        }

        public static OperatingSystem OSVersion
        {
            get
            {
                return m_OS;
            }
        }

    }
