¿Cómo se determina el uso de ASP.NET de 32 bit frente a 64 bit?

Question

Tengo un servidor ASP.NET al que no tengo acceso directo. ¿Cómo puedo escribir una aplicación .NET que determinará programáticamente si ASP.NET está ejecutando 32 bits frente a 64 bits?

Answer 1

ya ha respondido aquí:

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

Answer 2

Puede utilizar PInvoke

Este es un ejemplo de código encontró 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; 
    } 
} 

Answer 3

La manera más fácil es hacer esto:

Int32 addressWidth = IntPtr.Size * 8; 

desde IntPtr.Size es de 4 bytes en arquitectura de 32 bits y 8 bytes en la arquitectura de 64 bits.
