如何確定32位與64位ASP.NET正在使用？

我有一個我沒有直接訪問的ASP.NET服務器。我如何編寫一個.NET應用程序，以編程方式確定ASP.NET是否正在運行32位與64位？如何確定32位與64位ASP.NET正在使用？

已經回答了這裏：

How do I tell if my application is running as a 32-bit or 64-bit application?

您可以使用PInvoke

這是一個代碼示例發現here。

private enum Platform 
{ 
    X86, 
    X64, 
    Unknown 
} 

internal const ushort PROCESSOR_ARCHITECTURE_INTEL = 0; 
internal const ushort PROCESSOR_ARCHITECTURE_IA64 = 6; 
internal const ushort PROCESSOR_ARCHITECTURE_AMD64 = 9; 
internal const ushort PROCESSOR_ARCHITECTURE_UNKNOWN = 0xFFFF; 

[StructLayout(LayoutKind.Sequential)] 
internal struct SYSTEM_INFO 
{ 
    public ushort wProcessorArchitecture; 
    public ushort wReserved; 
    public uint dwPageSize; 
    public IntPtr lpMinimumApplicationAddress; 
    public IntPtr lpMaximumApplicationAddress; 
    public UIntPtr dwActiveProcessorMask; 
    public uint dwNumberOfProcessors; 
    public uint dwProcessorType; 
    public uint dwAllocationGranularity; 
    public ushort wProcessorLevel; 
    public ushort wProcessorRevision; 
}; 

[DllImport("kernel32.dll")] 
internal static extern void GetNativeSystemInfo(ref SYSTEM_INFO lpSystemInfo);   

private static Platform GetPlatform() 
{ 
    SYSTEM_INFO sysInfo = new SYSTEM_INFO(); 
    GetNativeSystemInfo(ref sysInfo); 

    switch (sysInfo.wProcessorArchitecture) 
    { 
     case PROCESSOR_ARCHITECTURE_AMD64: 
      return Platform.X64; 

     case PROCESSOR_ARCHITECTURE_INTEL: 
      return Platform.X86; 

     default: 
      return Platform.Unknown; 
    } 
}

這是一個很好的解決方案，如果你的.NET應用程序與強制x86上運行編譯標誌等原因，但你仍然需要確定主機系統64位。 – Mike 2009-12-17 13:54:27

最簡單的方法是做到這一點：

Int32 addressWidth = IntPtr.Size * 8;

因爲IntPtr.Size是4個字節在32位體系結構和在64位架構的8個字節。
