在 C# 中识别操作系统详细信息

Question

如何在 WPF 应用程序中使用 C# 代码获取操作系统详细信息？

Answer 1

Environment类提供可用于获取系统信息的属性。

Answer 2

您可以从系统获取操作系统信息。 Environment.OSVersion 这里

Answer 3

看看System.Environment它有属性OSVersion

Answer 4

由于我只需要关心非服务器版本，我这样做：

enum OS { _2000, XP, Vista, _7, _8 }

public static OS GetOS()
{
    var version = Environment.OSVersion.Version;
    switch (version.Major)
    {
        case 5:
            switch (version.Minor)
            {
                case 0:
                    return OS._2000;
                case 1:
                    return OS.XP;
                case 2:
                    return OS.XP; //could also be Server 2003, Server 2003 R2
            }
            break;
        case 6:
            switch (version.Minor)
            {
                case 0:
                    return OS.Vista; //could also be Server 2008
                case 1:
                    return OS._7; //could also be Server 2008 R2
                case 2:
                    return OS._8; //could also be Server 20012, Server 2012 R2
            }
            break;
    }

    throw new Exception("Strange OS");
}

如果您确实还需要考虑服务器版本，那么您的选择是：

1. WMI，您将不得不进行一些手动解析。 不确定用户权限是否会伤害非管理员用户。

2. GetVersionEx如本答案所述。

3. 检查ProductName在

   HKLM\\SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\

4. IsOS函数，如本答案所述。 我最喜欢这个..

Answer 5

使用注册表对于任何应用程序都是可能的。 在 C# 中，我为此创建了一个实用程序类。 请注意，Microsoft 已更改 Windows 10+ 的密钥（此类旨在处理）。 这门课应该给你你需要的信息，我认为：

namespace Inspection
{
    /// <summary>
    /// Static class that adds convenient methods for getting information on the running computers basic hardware and os setup.
    /// </summary>
    public static class ComputerInfo
    {
        /// <summary>
        ///     Returns the Windows major version number for this computer.
        /// </summary>
        public static uint WinMajorVersion
        {
            get
            {
                dynamic major;
                // The 'CurrentMajorVersionNumber' string value in the CurrentVersion key is new for Windows 10, 
                // and will most likely (hopefully) be there for some time before MS decides to change this - again...
                if (TryGeRegistryKey(@"SOFTWARE\Microsoft\Windows NT\CurrentVersion", "CurrentMajorVersionNumber", out major))
                {
                    return (uint) major;
                }

                // When the 'CurrentMajorVersionNumber' value is not present we fallback to reading the previous key used for this: 'CurrentVersion'
                dynamic version;
                if (!TryGeRegistryKey(@"SOFTWARE\Microsoft\Windows NT\CurrentVersion", "CurrentVersion", out version))
                    return 0;

                var versionParts = ((string) version).Split('.');
                if (versionParts.Length != 2) return 0;
                uint majorAsUInt;
                return uint.TryParse(versionParts[0], out majorAsUInt) ? majorAsUInt : 0;
            }
        }

        /// <summary>
        ///     Returns the Windows minor version number for this computer.

                    return 0;

                var versionParts = ((string) version).Split('.');
                if (versionParts.Length != 2) return 0;

                return uint.TryParse(versionParts[1], out minorAsUInt) ? minorAsUInt : 0;
