Wykryj wersję systemu Windows w .net

Jak mogę wykryć wersje systemu operacyjnego Windows w .net?

Jakiego kodu mogę użyć?

System.Environment.OSVersionzawiera informacje potrzebne do odróżnienia większości głównych wersji systemu operacyjnego Windows, ale nie wszystkich. Składa się z trzech komponentów, które są mapowane na następujące wersje systemu Windows:

W przypadku biblioteki, która pozwala uzyskać pełniejszy widok dokładnego wydania systemu Windows, w którym działa bieżące środowisko wykonawcze, zapoznaj się z tą biblioteką .

Ważna uwaga : jeśli plik wykonywalnego manifestu zestawu nie stwierdza jawnie, że zestaw exe jest zgodny z systemem Windows 8.1 i Windows 10.0, System.Environment.OSVersionzwróci wersję systemu Windows 8, czyli 6.2, zamiast 6.3 i 10.0! Źródło: tutaj .

Użyłem tego, gdy musiałem określić różne wersje systemu operacyjnego Microsoft:

string getOSInfo()
{
   //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;
}

Używam ManagementObjectSearcherprzestrzeni nazwSystem.Management

Przykład:

string r = "";
using (ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_OperatingSystem"))
{
    ManagementObjectCollection information = searcher.Get();
    if (information != null)
    {
        foreach (ManagementObject obj in information)
        {
            r = obj["Caption"].ToString() + " - " + obj["OSArchitecture"].ToString();
        }
    }
    r = r.Replace("NT 5.1.2600", "XP");
    r = r.Replace("NT 5.2.3790", "Server 2003");
    MessageBox.Show(r);
}

Nie zapomnij dodać referencji do zestawu System.Management.dll i umieścić using:using System.Management;

Dokumentacja

Jak zasugerował R. Bemrose, jeśli korzystasz z funkcji specyficznych dla systemu Windows 7, powinieneś zapoznać się z pakietem Windows® API Code Pack dla Microsoft® .NET Framework .

Zawiera CoreHelpersklasę, która pozwala określić system operacyjny, z którego aktualnie korzystasz (tylko XP i nowszy, jest to obecnie wymagane dla platformy .NET)

Zapewnia również wiele metod pomocniczych. Na przykład załóżmy, że chcesz użyć listy skoków systemu Windows 7, istnieje klasa, TaskbarManagerktóra udostępnia właściwość o nazwie IsPlatformSupportedi zwróci wartość true, jeśli używasz systemu Windows 7 lub nowszego.

Możesz użyć tej klasy pomocnika;

Za pośrednictwem Environment.OSVersionktórego „Pobiera obiekt System.OperatingSystem zawierający bieżący identyfikator platformy i numer wersji”.

Te wszystkie wydają się bardzo skomplikowanymi odpowiedziami na bardzo prostą funkcję:

public bool IsWindows7 
{ 
    get 
    { 
        return (Environment.OSVersion.Version.Major == 6 &
            Environment.OSVersion.Version.Minor == 1); 
    } 
}

Wykryj wersję systemu operacyjnego:

    public static string OS_Name()
    {
        return (string)(from x in new ManagementObjectSearcher(
            "SELECT Caption FROM Win32_OperatingSystem").Get().Cast<ManagementObject>() 
            select x.GetPropertyValue("Caption")).FirstOrDefault();
    }

To jest stosunkowo stare pytanie, ale ostatnio musiałem rozwiązać ten problem i nigdzie nie widziałem mojego rozwiązania.

Najłatwiejszym (i moim zdaniem najprostszym sposobem) jest użycie wywołania pinvoke do RtlGetVersion

[DllImport("ntdll.dll", SetLastError = true)]
internal static extern uint RtlGetVersion(out Structures.OsVersionInfo versionInformation); // return type should be the NtStatus enum

[StructLayout(LayoutKind.Sequential)]
internal struct OsVersionInfo
{
    private readonly uint OsVersionInfoSize;

    internal readonly uint MajorVersion;
    internal readonly uint MinorVersion;

    private readonly uint BuildNumber;

    private readonly uint PlatformId;

    [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 128)]
    private readonly string CSDVersion;
}

Gdzie główne i drugorzędne numery wersji w tej strukturze odpowiadają wartościom w tabeli zaakceptowanej odpowiedzi.

Zwraca prawidłowy numer wersji systemu Windows, w przeciwieństwie do przestarzałych funkcji GetVersion i GetVersionEx z kernel32

1. Dodaj odniesienie do Microsoft.VisualBasic.
2. Uwzględnij przestrzeń nazw using Microsoft.VisualBasic.Devices;
3. Posługiwać się new ComputerInfo().OSFullName

Zwracana wartość to „Microsoft Windows 10 Enterprise”

Jednokierunkowa:

public string GetOSVersion()
{
  int _MajorVersion = Environment.OSVersion.Version.Major;

  switch (_MajorVersion) {
    case 5:
      return "Windows XP";
    case 6:
      switch (Environment.OSVersion.Version.Minor) {
        case 0:
          return "Windows Vista";
        case 1:
          return "Windows 7";
        default:
          return "Windows Vista & above";
      }
      break;
    default:
      return "Unknown";
  }
}

Następnie po prostu zawiń zaznaczoną wielkość liter wokół funkcji.

Co powiesz na użycie rejestru, aby uzyskać nazwę.

„HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion” ma wartość ProductName od wersji Windows XP.

[DllImport("kernel32.dll")]
static extern IntPtr GetCurrentProcess();

[DllImport("kernel32.dll")]
static extern IntPtr GetModuleHandle(string moduleName);

[DllImport("kernel32")]
static extern IntPtr GetProcAddress(IntPtr hModule, string procName);

[DllImport("kernel32.dll")]
static extern bool IsWow64Process(IntPtr hProcess, out bool wow64Process);

public static bool Is64BitOperatingSystem()
{
    // Check if this process is natively an x64 process. If it is, it will only run on x64 environments, thus, the environment must be x64.
    if (IntPtr.Size == 8)
        return true;
    // Check if this process is an x86 process running on an x64 environment.
    IntPtr moduleHandle = GetModuleHandle("kernel32");
    if (moduleHandle != IntPtr.Zero)
    {
        IntPtr processAddress = GetProcAddress(moduleHandle, "IsWow64Process");
        if (processAddress != IntPtr.Zero)
        {
            bool result;
            if (IsWow64Process(GetCurrentProcess(), out result) && result)
                return true;
        }
    }
    // The environment must be an x86 environment.
    return false;
}

private static string HKLM_GetString(string key, string value)
{
    try
    {
        RegistryKey registryKey = Registry.LocalMachine.OpenSubKey(key);
        return registryKey?.GetValue(value).ToString() ?? String.Empty;
    }
    catch
    {
        return String.Empty;
    }
}

public static string GetWindowsVersion()
{
    string osArchitecture;
    try
    {
        osArchitecture = Is64BitOperatingSystem() ? "64-bit" : "32-bit";
    }
    catch (Exception)
    {
        osArchitecture = "32/64-bit (Undetermined)";
    }
    string productName = HKLM_GetString(@"SOFTWARE\Microsoft\Windows NT\CurrentVersion", "ProductName");
    string csdVersion = HKLM_GetString(@"SOFTWARE\Microsoft\Windows NT\CurrentVersion", "CSDVersion");
    string currentBuild = HKLM_GetString(@"SOFTWARE\Microsoft\Windows NT\CurrentVersion", "CurrentBuild");
    if (!string.IsNullOrEmpty(productName))
    {
        return
            $"{productName}{(!string.IsNullOrEmpty(csdVersion) ? " " + csdVersion : String.Empty)} {osArchitecture} (OS Build {currentBuild})";
    }
    return String.Empty;
}

Jeśli używasz .NET Framework 4.0 lub nowszego. Możesz usunąć metodę Is64BitOperatingSystem () i użyć Environment.Is64BitOperatingSystem .

Pierwsze rozwiązanie

Aby upewnić się, że otrzymujesz odpowiednią wersję Environment.OSVersion, należy dodać app.manifestprzy użyciu programu Visual Studio i odkomentować następujące supportedOStagi:

  <compatibility xmlns="urn:schemas-microsoft-com:compatibility.v1">
    <application>
      <!-- A list of the Windows versions that this application has been tested on
           and is designed to work with. Uncomment the appropriate elements
           and Windows will automatically select the most compatible environment. -->

      <!-- Windows Vista -->
      <supportedOS Id="{e2011457-1546-43c5-a5fe-008deee3d3f0}" />

      <!-- Windows 7 -->
      <supportedOS Id="{35138b9a-5d96-4fbd-8e2d-a2440225f93a}" />

      <!-- Windows 8 -->
      <supportedOS Id="{4a2f28e3-53b9-4441-ba9c-d69d4a4a6e38}" />

      <!-- Windows 8.1 -->
      <supportedOS Id="{1f676c76-80e1-4239-95bb-83d0f6d0da78}" />

      <!-- Windows 10 -->
      <supportedOS Id="{8e0f7a12-bfb3-4fe8-b9a5-48fd50a15a9a}" />

    </application>
  </compatibility>

Następnie w swoim kodzie możesz użyć w Environment.OSVersionten sposób:

var version = System.Environment.OSVersion;
Console.WriteLine(version);

Przykład

Na przykład w moim machine ( Windows 10.0 Build 18362.476) wynik byłby taki, który jest nieprawidłowy :

Microsoft Windows NT 6.2.9200.0

Dodając app.manifesti odkomentowując te tagi uzyskam odpowiedni numer wersji:

Microsoft Windows NT 10.0.18362.0

Alternatywne rozwiązanie

Jeśli nie lubisz dodawać app.manifestdo projektu, możesz użyć tego, OSDescriptionktóry jest dostępny od wersji .NET Framework 4.7.1 i .NET Core 1.0.

string description = RuntimeInformation.OSDescription;

Uwaga: nie zapomnij dodać następującego wyrażenia using na początku pliku.

using System.Runtime.InteropServices;

Możesz przeczytać więcej o tym i obsługiwanych platformach tutaj .

Powyższe odpowiedzi dałyby mi Majorwersję 6na Windows 10.

Rozwiązanie, które odkryłem, że działa bez dodawania dodatkowych bibliotek VB, było następujące:

var versionString = (string)Microsoft.Win32.Registry.LocalMachine.OpenSubKey("Software\\Microsoft\\Windows NT\\CurrentVersion")?.GetValue("productName");

Nie uważałbym tego za najlepszy sposób na uzyskanie wersji, ale zaletą jest to, że oneliner nie ma dodatkowych bibliotek, aw moim przypadku sprawdzenie, czy zawiera, "10"było wystarczająco dobre.

Nie komplikuj zbytnio problemu.

string osVer = System.Environment.OSVersion.Version.ToString();

if (osVer.StartsWith("5")) // windows 2000, xp win2k3
{
    MessageBox.Show("xp!");
}
else // windows vista and windows 7 start with 6 in the version #
{
    MessageBox.Show("Win7!");
}
