1. 概述

从 Windows 10 开始,微软已经弃用了 GetVersionEx 方式获取 Windows 系统版本[官方解释]。这就导致网上一大批C#获取 Windows 版本的代码把 Windows 10 识别为 Windows 8。比如我的电脑 Windows 10 就被识别成 6.2.9200,进而判断出是 Windows 8。

按照微软官方论坛提示,可以通过 WMI(Windows Management Instruction) 获取正确系统的版本号。下面把传统获取方式、WMI获取方式和直接获取操作系统名称的三个方法列出来。

2. 展示

2.1 传统获取方式(弃用)

传统获取 Windows 系统版本的方法:先获取 Windows 系统的版本号,再通过版本号比对出操作系统名称。

public static string get_OSVersion()
{
    //Get Operating system information.
    OperatingSystem os = Environment.OSVersion;
    //Get version information about the os.
    Version vs = os.Version;

    //Variable to hold our return value
    string operatingSystem = "";

    if (os.Platform == PlatformID.Win32Windows)
    {
        //This is a pre-NT version of Windows
        switch (vs.Minor)
        {
            case 0:
                operatingSystem = "95";
                break;
            case 10:
                if (vs.Revision.ToString() == "2222A")
                    operatingSystem = "98SE";
                else
                    operatingSystem = "98";
                break;
            case 90:
                operatingSystem = "Me";
                break;
            default:
                break;
        }
    }
    else if (os.Platform == PlatformID.Win32NT)
    {
        switch (vs.Major)
        {
            case 3:
                operatingSystem = "NT 3.51";
                break;
            case 4:
                operatingSystem = "NT 4.0";
                break;
            case 5:
                if (vs.Minor == 0)
                    operatingSystem = "2000";
                else
                    operatingSystem = "XP";
                break;
            case 6:
                if (vs.Minor == 0)
                    operatingSystem = "Vista";
                else if (vs.Minor == 1)
                    operatingSystem = "7";
                else if (vs.Minor == 2)
                    operatingSystem = "8";
                else
                    operatingSystem = "8.1";
                break;
            case 10:
                operatingSystem = "10";
                break;
            default:
                break;
        }
    }
    //Make sure we actually got something in our OS check
    //We don't want to just return " Service Pack 2" or " 32-bit"
    //That information is useless without the OS version.
    if (operatingSystem != "")
    {
        //Got something.  Let's prepend "Windows" and get more info.
        operatingSystem = "Windows " + operatingSystem;
        //See if there's a service pack installed.
        if (os.ServicePack != "")
        {
            //Append it to the OS name.  i.e. "Windows XP Service Pack 3"
            operatingSystem += " " + os.ServicePack;
        }
        //Append the OS architecture.  i.e. "Windows XP Service Pack 3 32-bit"
        //operatingSystem += " " + getOSArchitecture().ToString() + "-bit";
    }
    //Return the information we've gathered.
    return operatingSystem;
}

3.2 通过 WMI 获取操作系统版本

public static string get_OSVersion()
{
    try
    {
        ManagementObject mo = GetMngObj("Win32_OperatingSystem");

        if (null == mo)
            return string.Empty;

        return mo["Version"] as string;
    }
    catch (Exception e)
    {
        return string.Empty;
    }
}

如下图所示,获取 Windows 10 操作系统版本号正确。

3.3 直接获取操作系统名称

根据下面的 Windows 操作系统名称和版本好的对应关系表,可以发现很多不同系列的操作系统拥有相同的主版本号和子版本号,因此通过比对版本号的方式来判断操作系统名称是很不靠谱。

本文提供了一种简单获取操作系统名称的方式:

 new ComputerInfo().OSFullName

需要引用库:using Microsoft.VisualBasic.Devices;

实际测试了 Windows 10 、Windows 2012 R2 和 Windows 2008 R2,如下图所示:

以上,其他版本的操作系统如果获取有问题,还请留言告知,谢谢!
