System.Environment.OSVersion には、ほとんどのWindows OSメジャーリリースを区別するために必要な情報がありますが、すべてではありません。次のWindowsバージョンにマップする3つのコンポーネントで構成されます。

| Windows 98 | Win32Windows | 4 | 10 |

重要な注意事項：実行可能なアセンブリマニフェストに、exeアセンブリがWindows 8.1およびWindows 10.0と互換性があると明示的に記述されていない場合、System.Environment.OSVersionはWindows 8.0バージョンを返します。 6.3および10.0ではなく6.2です!!ソース： here 。

R. Bemroseが提案したように、Windows 7固有の機能を実行している場合は、 Microsoft®.NET Framework用のWindows®APIコードパック をご覧ください。
現在使用しているOSを判別できるCoreHelpersクラスが含まれています（XP以降のみ、現在の.NETの要件）
また、複数のヘルパーメソッドも提供します。たとえば、Windows 7のジャンプリストを使用する場合、TaskbarManagerというプロパティを提供するIsPlatformSupportedクラスがあり、Windows 7以上の場合はtrueを返します。

名前空間System.ManagementのManagementObjectSearcherを使用します
例：
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);

これらはすべて、非常に単純な関数に対する非常に複雑な答えのようです。

Environment.OSVersion.Version.Minor == 1);

{
return (string)(from x in new ManagementObjectSearcher(
"SELECT Caption FROM Win32_OperatingSystem").Get().Cast<ManagementObject>()
select x.GetPropertyValue("Caption")).FirstOrDefault();
}
一方通行：

.NET Framework 4.0以降を使用している場合。 Is64BitOperatingSystem（）メソッドを削除して、 Environment.Is64BitOperatingSystem を使用できます。
これは比較的古い質問ですが、最近この問題を解決しなければならず、自分のソリューションがどこにも掲載されていませんでした。
最も簡単な（そして私の意見では最も簡単な方法）は、RtlGetVersionのpinvoke呼び出しを使用することです
[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;
}
この構造体のメジャーバージョン番号とマイナーバージョン番号は、受け入れられた回答の表の値に対応しています。
これは、kernel32の非推奨のGetVersionおよびGetVersionEx関数とは異なり、正しいWindowsバージョン番号を返します
