Deteksi versi Windows di .net

Bagaimana saya bisa mendeteksi versi OS Windows di .net?

Kode apa yang bisa saya gunakan?

System.Environment.OSVersionmemiliki informasi yang Anda perlukan untuk membedakan sebagian besar rilis utama OS Windows, tetapi tidak semua. Ini terdiri dari tiga komponen yang memetakan ke versi Windows berikut:

Untuk perpustakaan yang memungkinkan Anda untuk mendapatkan tampilan yang lebih lengkap tentang tepat peluncuran Windows bahwa lingkungan eksekusi saat ini sedang berjalan di, memeriksa perpustakaan ini .

Catatan penting : jika manifes rakitan yang dapat dieksekusi Anda tidak secara eksplisit menyatakan bahwa rakitan exe Anda kompatibel dengan Windows 8.1 dan Windows 10.0, System.Environment.OSVersionakan mengembalikan versi Windows 8, yaitu 6.2, bukan 6.3 dan 10.0! Sumber: di sini .

Saya menggunakan ini ketika saya harus menentukan berbagai versi Sistem Operasi 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;
}

Saya menggunakan ManagementObjectSearchernamespaceSystem.Management

Contoh:

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);
}

Jangan lupa untuk menambahkan referensi ke Majelis System.Management.dll dan menggunakan:using System.Management;

Seperti yang disarankan R. Bemrose, jika Anda melakukan fitur spesifik Windows 7, Anda harus melihat Paket Kode API Windows® untuk Microsoft® .NET Framework .

Berisi a CoreHelpers kelas yang memungkinkan Anda menentukan OS Anda saat ini (hanya XP dan di atasnya, itu persyaratan untuk .NET nowaday)

Ini juga menyediakan beberapa metode pembantu. Misalnya, anggap Anda ingin menggunakan daftar lompatan Windows 7, ada kelas TaskbarManageryang menyediakan properti yang dipanggil IsPlatformSupporteddan itu akan mengembalikan true jika Anda berada di Windows 7 dan di atasnya.

Anda bisa menggunakan kelas pembantu ini;

Melalui Environment.OSVersionmana "Mendapat objek System.OperatingSystem objek yang berisi pengidentifikasi platform saat ini dan nomor versi."

Semua ini sepertinya jawaban yang sangat rumit untuk fungsi yang sangat sederhana:

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

Deteksi Versi OS:

    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();
    }

Ini adalah pertanyaan yang relatif lama tetapi saya baru saja menyelesaikan masalah ini dan tidak melihat solusi saya diposting di mana pun.

Cara termudah (dan paling sederhana menurut saya) adalah dengan hanya menggunakan panggilan pinvoke ke 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;
}

Di mana nomor versi Major dan Minor dalam struct ini sesuai dengan nilai-nilai dalam tabel jawaban yang diterima.

Ini mengembalikan nomor versi Windows yang benar tidak seperti fungsi GetVersion & GetVersionEx yang sudah usang dari kernel32

1. Tambahkan referensi ke Microsoft.VisualBasic.
2. Sertakan namespace using Microsoft.VisualBasic.Devices;
3. Menggunakan new ComputerInfo().OSFullName

Nilai kembali adalah "Microsoft Windows 10 Enterprise"

Satu arah:

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";
  }
}

Maka cukup bungkus kasus pilih di sekitar fungsi.

Bagaimana kalau menggunakan Registry untuk mendapatkan nama.

"HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion" memiliki nilai ProductName sejak 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;
}

Jika Anda menggunakan .NET Framework 4.0 atau lebih tinggi. Anda dapat menghapus metode Is64BitOperatingSystem () dan menggunakan Lingkungan.Is64BitOperatingSystem .

Solusi pertama

Untuk memastikan Anda mendapatkan versi yang tepat, Environment.OSVersionAnda harus menambahkan app.manifestmenggunakan Visual Studio dan menghapus tanda komentar berikut supportedOS:

  <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>

Kemudian dalam kode Anda, Anda dapat menggunakan Environment.OSVersionseperti ini:

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

Contoh

Misalnya di mesin saya ( Windows 10.0 Build 18362.476) hasilnya akan seperti ini yang tidak benar :

Microsoft Windows NT 6.2.9200.0

Dengan menambahkan app.manifest dan menghapus tanda komentar pada tag tersebut, saya akan mendapatkan nomor versi yang benar:

Microsoft Windows NT 10.0.18362.0

Solusi alternatif

Jika Anda tidak suka menambahkan app.manifest ke proyek Anda, Anda dapat menggunakan OSDescriptionyang tersedia sejak .NET Framework 4.7.1 dan .NET Core 1.0.

string description = RuntimeInformation.OSDescription;

Catatan: Jangan lupa untuk menambahkan pernyataan menggunakan berikut di atas file Anda.

using System.Runtime.InteropServices;

Anda dapat membaca lebih lanjut tentang hal ini dan platform yang didukung di sini .

Jawaban di atas akan memberi saya Majorversi6 pada Windows 10.

Solusi yang saya temukan berfungsi tanpa menambahkan pustaka VB tambahan adalah sebagai berikut:

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

Saya tidak akan menganggap ini cara terbaik untuk mendapatkan versi, tetapi sisi baiknya ini adalah oneliner tidak ada perpustakaan tambahan, dan dalam kasus saya memeriksa apakah isinya "10"cukup baik.

Jangan terlalu memperumit masalah.

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!");
}
