[英]How to find if a native DLL file is compiled as x64 or x86?
我想確定本機程序集是否從托管代碼應用程序 (C# ) 編譯為 x64 或 x86。
我認為它必須在 PE 標頭中的某個位置,因為操作系統加載程序需要知道此信息,但我找不到它。 當然我更喜歡用托管代碼來做,但如果有必要,我可以使用原生 C++。
您也可以使用DUMPBIN 。 使用/headers
或/all
標志及其列出的第一個文件頭。

'find' 可以讓生活稍微輕松一點:
dumpbin /headers cv210.dll |find "machine"
8664 machine (x64)
使用CorFlags有一種簡單的方法可以做到這一點。 打開 Visual Studio 命令提示符並鍵入“corflags [你的程序集]”。 你會得到這樣的東西:
c:\\Program Files (x86)\\Microsoft Visual Studio 9.0\\VC>corflags "C:\\Windows\\Microsoft.NET\\Framework\\v2.0.50727\\System.Data.dll"
Microsoft (R) .NET Framework CorFlags 轉換工具。 版本 3.5.21022.8 版權所有 (c) Microsoft Corporation。 版權所有。
版本:v2.0.50727 CLR 標頭:2.5 PE:PE32 CorFlags:24 ILONLY:0 32BIT:0 簽名:1
您正在專門研究 PE 和 32BIT。
任何 CPU :
聚乙烯:PE32
32位:0
x86 :
聚乙烯:PE32
32位:1
x64:
聚乙烯:PE32+
32位:0
這個技巧有效並且只需要記事本。
使用文本編輯器(如記事本)打開 dll 文件並找到第一次出現的字符串PE
。 以下字符定義 dll 是 32 位還是 64 位。
PE L
PE d†
IMAGE_OPTIONAL_HEADER
的Magic
字段(盡管 Windows 可執行映像(DLL/EXE 文件)中的標頭沒有任何可選內容)將告訴您 PE 的體系結構。
這是從文件中獲取架構的示例。
public static ushort GetImageArchitecture(string filepath) {
using (var stream = new System.IO.FileStream(filepath, System.IO.FileMode.Open, System.IO.FileAccess.Read))
using (var reader = new System.IO.BinaryReader(stream)) {
//check the MZ signature to ensure it's a valid Portable Executable image
if (reader.ReadUInt16() != 23117)
throw new BadImageFormatException("Not a valid Portable Executable image", filepath);
// seek to, and read, e_lfanew then advance the stream to there (start of NT header)
stream.Seek(0x3A, System.IO.SeekOrigin.Current);
stream.Seek(reader.ReadUInt32(), System.IO.SeekOrigin.Begin);
// Ensure the NT header is valid by checking the "PE\0\0" signature
if (reader.ReadUInt32() != 17744)
throw new BadImageFormatException("Not a valid Portable Executable image", filepath);
// seek past the file header, then read the magic number from the optional header
stream.Seek(20, System.IO.SeekOrigin.Current);
return reader.ReadUInt16();
}
}
目前僅有的兩個架構常量是:
0x10b - PE32
0x20b - PE32+
干杯
更新我發布這個答案已經有一段時間了,但我仍然看到它時不時地得到一些贊成,所以我認為它值得更新。 我編寫了一種獲取Portable Executable
映像架構的方法,該方法還會檢查它是否被編譯為AnyCPU
。 不幸的是,答案是在 C++ 中,但如果您有幾分鍾時間在WinNT.h
查找結構, WinNT.h
移植到 C# 應該不會WinNT.h
。 如果人們有興趣,我會用 C# 編寫一個端口,但除非人們真的想要它,否則我不會花太多時間來強調它。
#include <Windows.h>
#define MKPTR(p1,p2) ((DWORD_PTR)(p1) + (DWORD_PTR)(p2))
typedef enum _pe_architecture {
PE_ARCHITECTURE_UNKNOWN = 0x0000,
PE_ARCHITECTURE_ANYCPU = 0x0001,
PE_ARCHITECTURE_X86 = 0x010B,
PE_ARCHITECTURE_x64 = 0x020B
} PE_ARCHITECTURE;
LPVOID GetOffsetFromRva(IMAGE_DOS_HEADER *pDos, IMAGE_NT_HEADERS *pNt, DWORD rva) {
IMAGE_SECTION_HEADER *pSecHd = IMAGE_FIRST_SECTION(pNt);
for(unsigned long i = 0; i < pNt->FileHeader.NumberOfSections; ++i, ++pSecHd) {
// Lookup which section contains this RVA so we can translate the VA to a file offset
if (rva >= pSecHd->VirtualAddress && rva < (pSecHd->VirtualAddress + pSecHd->Misc.VirtualSize)) {
DWORD delta = pSecHd->VirtualAddress - pSecHd->PointerToRawData;
return (LPVOID)MKPTR(pDos, rva - delta);
}
}
return NULL;
}
PE_ARCHITECTURE GetImageArchitecture(void *pImageBase) {
// Parse and validate the DOS header
IMAGE_DOS_HEADER *pDosHd = (IMAGE_DOS_HEADER*)pImageBase;
if (IsBadReadPtr(pDosHd, sizeof(pDosHd->e_magic)) || pDosHd->e_magic != IMAGE_DOS_SIGNATURE)
return PE_ARCHITECTURE_UNKNOWN;
// Parse and validate the NT header
IMAGE_NT_HEADERS *pNtHd = (IMAGE_NT_HEADERS*)MKPTR(pDosHd, pDosHd->e_lfanew);
if (IsBadReadPtr(pNtHd, sizeof(pNtHd->Signature)) || pNtHd->Signature != IMAGE_NT_SIGNATURE)
return PE_ARCHITECTURE_UNKNOWN;
// First, naive, check based on the 'Magic' number in the Optional Header.
PE_ARCHITECTURE architecture = (PE_ARCHITECTURE)pNtHd->OptionalHeader.Magic;
// If the architecture is x86, there is still a possibility that the image is 'AnyCPU'
if (architecture == PE_ARCHITECTURE_X86) {
IMAGE_DATA_DIRECTORY comDirectory = pNtHd->OptionalHeader.DataDirectory[IMAGE_DIRECTORY_ENTRY_COM_DESCRIPTOR];
if (comDirectory.Size) {
IMAGE_COR20_HEADER *pClrHd = (IMAGE_COR20_HEADER*)GetOffsetFromRva(pDosHd, pNtHd, comDirectory.VirtualAddress);
// Check to see if the CLR header contains the 32BITONLY flag, if not then the image is actually AnyCpu
if ((pClrHd->Flags & COMIMAGE_FLAGS_32BITREQUIRED) == 0)
architecture = PE_ARCHITECTURE_ANYCPU;
}
}
return architecture;
}
該函數接受一個指向內存中 PE 映像的指針(因此您可以選擇如何獲取它的毒葯;內存映射或將整個內容讀入內存......無論如何)。
對於非托管 DLL 文件,您需要首先檢查它是否是 16 位 DLL 文件(希望不是)。 然后檢查IMAGE\\_FILE_HEADER.Machine
字段。
其他人已經花時間解決了這個問題,所以我在這里重復一遍:
要區分 32 位和 64 位 PE 文件,您應該檢查 IMAGE_FILE_HEADER.Machine 字段。 基於下面的 Microsoft PE 和 COFF 規范,我列出了該字段的所有可能值: http : //download.microsoft.com/download/9/c/5/9c5b2167-8017-4bae-9fde-d599bac8184a/ pecoff_v8.doc
IMAGE_FILE_MACHINE_UNKNOWN 0x0 該字段的內容假定適用於任何機器類型
IMAGE_FILE_MACHINE_AM33 0x1d3 松下 AM33
IMAGE_FILE_MACHINE_AMD64 0x8664 x64
IMAGE_FILE_MACHINE_ARM 0x1c0 ARM 小端
IMAGE_FILE_MACHINE_EBC 0xebc EFI 字節碼
IMAGE_FILE_MACHINE_I386 0x14c Intel 386 或更高版本處理器和兼容處理器
IMAGE_FILE_MACHINE_IA64 0x200 英特爾安騰處理器家族
IMAGE_FILE_MACHINE_M32R 0x9041 三菱 M32R 小端
IMAGE_FILE_MACHINE_MIPS16 0x266 MIPS16
IMAGE_FILE_MACHINE_MIPSFPU 0x366 MIPS 帶 FPU
IMAGE_FILE_MACHINE_MIPSFPU16 0x466 MIPS16 帶 FPU
IMAGE_FILE_MACHINE_POWERPC 0x1f0 Power PC 小端
IMAGE_FILE_MACHINE_POWERPCFP 0x1f1 具有浮點支持的 Power PC
IMAGE_FILE_MACHINE_R4000 0x166 MIPS 小端
IMAGE_FILE_MACHINE_SH3 0x1a2 日立 SH3
IMAGE_FILE_MACHINE_SH3DSP 0x1a3 日立 SH3 DSP
IMAGE_FILE_MACHINE_SH4 0x1a6 日立 SH4
IMAGE_FILE_MACHINE_SH5 0x1a8 日立 SH5
IMAGE_FILE_MACHINE_THUMB 0x1c2 拇指
IMAGE_FILE_MACHINE_WCEMIPSV2 0x169 MIPS 小端 WCE v2
是的,您可以檢查 IMAGE_FILE_MACHINE_AMD64|IMAGE_FILE_MACHINE_IA64 為 64 位和 IMAGE_FILE_MACHINE_I386 為 32 位。
64 位二進制文件以 PE32+ 格式存儲。 嘗試閱讀http://www.masm32.com/board/index.php?action=dlattach;topic=6687.0;id=3486
我在 powershell 腳本的第一個答案中重寫了c++ 解決方案。 腳本可以確定此類 .exe 和 .dll 文件:

如果不需要查看詳細信息,可以省略第二個參數
這里描述了一種快速且可能骯臟的方法: https : //superuser.com/a/889267 。 在編輯器中打開 DLL 並檢查“PE”序列后的第一個字符。
顯然,您可以在可移植可執行文件的標題中找到它。 corflags.exe 實用程序能夠顯示它是否面向 x64。 希望這可以幫助您找到有關它的更多信息。
由於第三方工具總是安裝在%Program files (x86)%
(即使 x64 安裝!)並且需要首先在%path%
上列出適當的 x32|x64 fortran 運行時才能正確運行,我收集了c++和powershell解決方案進入matlab返回:
