如何确定哪个版本的Windows？
- 如何确定哪个版本的Windows？ WinXP，Vista或7等
- 32位还是64位？
UPD：for .Net 2.0 – 3.5
您正在寻找Environment.OSVersion ， Environment.Is64BitProcess和Environment.Is64BitOperatingSystem属性。
在.Net 4.0之前，您可以通过检查IntPtr.Size是否为8来检查进程是否为64位，并且您可以使用以下代码检查操作系统是否为64位：
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);
看看Environment.OSVersion和Environment.Is64BitOperatingSystem
你可以做到
System.OperatingSystem osInfo = System.Environment.OSVersion;
看看这个 。
