- 如何确定Windows的哪个版本?WinXP、Vista或7等
- 32位还是64位
UPD:适用于.Net 2.0-3.5
您正在查找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,并且可以使用以下代码检查操作系统是否为64比特:
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);
查看Environment.OSVersion
和Environment.Is64BitOperatingSystem
您可以进行
System.OperatingSystem osInfo = System.Environment.OSVersion;
看看这个。
