- 如何确定哪个版本的 Windows? WinXP、Vista 或 7 等
- 32 位还是 64 位?
UPD:适用于 .Net 2.0 - 3.5
最佳答案
您正在查找 Environment.OSVersion
、Environment.Is64BitProcess
和 Environment.Is64BitOperatingSystem
属性。
在.Net 4.0之前,可以通过检查IntPtr.Size
是否为8
来判断进程是否为64位,而你可以使用 this code 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);
