如何获得"友好"的操作系统版本名称？

您应该尽量避免WMI供本地使用.这是非常方便的,但你在性能方面付出了巨大的代价.这很简单:

    public string HKLM_GetString(string path, string key)
    {
        try
        {
            RegistryKey rk = Registry.LocalMachine.OpenSubKey(path);
            if (rk == null) return "";
            return (string)rk.GetValue(key);
        }
        catch { return ""; }
    }

    public string FriendlyName()
    {
        string ProductName = HKLM_GetString(@"SOFTWARE\Microsoft\Windows NT\CurrentVersion", "ProductName");
        string CSDVersion = HKLM_GetString(@"SOFTWARE\Microsoft\Windows NT\CurrentVersion", "CSDVersion");
        if (ProductName != "")
        {
            return (ProductName.StartsWith("Microsoft") ? "" : "Microsoft ") + ProductName +
                        (CSDVersion != "" ? " " + CSDVersion : "");
        }
        return "";
    }

为什么不用Environment.OSVersion？它还会告诉你这是什么操作--Windows,Mac OS X,Unix等.要查明你是在64位还是32位运行,请使用IntPtr.Size- 这将返回4位为32位,8位为64位.

尝试:

new ComputerInfo().OSVersion;

输出:

Microsoft Windows 10企业版

注意: 添加引用Microsoft.VisualBasic.Devices;

样本输出:

Name = Windows Vista
Edition = Home Premium
Service Pack = Service Pack 1
Version = 6.0.6001.65536
Bits = 64

样本类:

class Program
{
    static void Main( string[] args )
    {
        Console.WriteLine( "Operation System Information" );
        Console.WriteLine( "----------------------------" );
        Console.WriteLine( "Name = {0}", OSInfo.Name );
        Console.WriteLine( "Edition = {0}", OSInfo.Edition );
        Console.WriteLine( "Service Pack = {0}", OSInfo.ServicePack );
        Console.WriteLine( "Version = {0}", OSInfo.VersionString );
        Console.WriteLine( "Bits = {0}", OSInfo.Bits );
        Console.ReadLine();
    }
}

OSInfo类的源代码:http://www.csharp411.com/determine-windows-version-and-edition-with-c/但是代码中有错误,您需要替换"case 6"语句(就在#endregion NAME之前)这个:

case 6:
    switch (minorVersion)
    {
        case 0:

            switch (productType)
            {
                case 1:
                    name = "Windows Vista";
                    break;
                case 3:
                    name = "Windows Server 2008";
                    break;
            }
            break;
        case 1:
            switch (productType)
            {
                case 1:
                    name = "Windows 7";
                    break;
                case 3:
                    name = "Windows Server 2008 R2";
                    break;
            }
            break;
    }
    break;

如果你想更进一步,看看你的程序是以64位还是32位运行:

public static class Wow
{
    public static bool Is64BitProcess
    {
        get { return IntPtr.Size == 8; }
    }

    public static bool Is64BitOperatingSystem
    {
        get
        {
            // Clearly if this is a 64-bit process we must be on a 64-bit OS.
            if (Is64BitProcess)
                return true;
            // Ok, so we are a 32-bit process, but is the OS 64-bit?
            // If we are running under Wow64 than the OS is 64-bit.
            bool isWow64;
            return ModuleContainsFunction("kernel32.dll", "IsWow64Process") && IsWow64Process(GetCurrentProcess(), out isWow64) && isWow64;
        }
    }

    static bool ModuleContainsFunction(string moduleName, string methodName)
    {
        IntPtr hModule = GetModuleHandle(moduleName);
        if (hModule != IntPtr.Zero)
            return GetProcAddress(hModule, methodName) != IntPtr.Zero;
        return false;
    }

    [DllImport("kernel32.dll", SetLastError = true)]
    [return: MarshalAs(UnmanagedType.Bool)]
    extern static bool IsWow64Process(IntPtr hProcess, [MarshalAs(UnmanagedType.Bool)] out bool isWow64);
    [DllImport("kernel32.dll", CharSet = CharSet.Auto, SetLastError = true)]
    extern static IntPtr GetCurrentProcess();
    [DllImport("kernel32.dll", CharSet = CharSet.Auto)]
    extern static IntPtr GetModuleHandle(string moduleName);
    [DllImport("kernel32.dll", CharSet = CharSet.Ansi, SetLastError = true)]
    extern static IntPtr GetProcAddress(IntPtr hModule, string methodName);
}
