我怎么能确定哪种平台的可执行编译？ [英] How can I determine for which platform an executable is compiled?

问题描述

我有必要与这些针对x86，x64和IA64做Windows可执行文件的工作。我想通过检查文件本身以编程方式找出平台。

I have a need to work with Windows executables which are made for x86, x64, and IA64. I'd like to programmatically figure out the platform by examining the files themselves.

我的目标语言的PowerShell但C＃示例会做。无论是失败的那些，如果你知道所需要的逻辑将是巨大的。

My target language is PowerShell but a C# example will do. Failing either of those, if you know the logic required that would be great.

推荐答案

（从另一个Q，因为删除）

(from another Q, since removed)

机器类型：这是基于一些获取链接时间戳code口的快速点点。这是相同的标题，它似乎工作 - 它返回时，I386与作为目标平台编译编译 - 任何CPU-时，和x64

Machine type: This is a quick little bit of code I based on some that gets the linker timestamp. This is in the same header, and it seems to work - it returns I386 when compiled -any cpu-, and x64 when compiled with that as the target platform.

在探索PE头（K.斯坦顿，MSDN）博客条目，向我展示了偏移，作为另一个回应指出。

The Exploring PE Headers (K. Stanton,MSDN) blog entry that showed me the offset, as another response noted.

public enum MachineType {
    Native = 0, I386 = 0x014c, Itanium = 0x0200, x64 = 0x8664
}

public static MachineType GetMachineType(string fileName)
{
    const int PE_POINTER_OFFSET = 60;            
    const int MACHINE_OFFSET = 4;
    byte[] data = new byte[4096];
    using (Stream s = new FileStream(fileName, FileMode.Open, FileAccess.Read)) {
        s.Read(data, 0, 4096);
    }
    // dos header is 64 bytes, last element, long (4 bytes) is the address of the PE header
    int PE_HEADER_ADDR = BitConverter.ToInt32(data, PE_POINTER_OFFSET);
    int machineUint = BitConverter.ToUInt16(data, PE_HEADER_ADDR + MACHINE_OFFSET);
    return (MachineType)machineUint;
}
