检查.NET程序集的目标平台的另一种方法是使用.NET Reflector检查程序集…

@ # ~ #€~ !我刚刚意识到新版本不是免费的!因此，更正一下，如果你有一个。net reflector的免费版本，你可以用它来检查目标平台。

cfeduke注意到调用GetPEKind的可能性。在PowerShell中进行这个操作可能会很有趣。

例如，下面是可以使用的cmdlet代码:https://stackoverflow.com/a/16181743/64257

另外，在https://stackoverflow.com/a/4719567/64257网站上提到“PowerShell社区扩展中也有Get-PEHeader cmdlet，可以用来测试可执行图像。”

下面是一个批处理文件，它将针对当前工作目录和所有子目录中的所有DLL文件和EXE文件运行corflags.exe，解析结果并显示每个目标体系结构。

Depending on the version of corflags.exe that is used, the line items in the output will either include 32BIT, or 32BITREQ (and 32BITPREF). Whichever of these two is included in the output is the critical line item that must be checked to differentiate between Any CPU and x86. If you are using an older version of corflags.exe (pre Windows SDK v8.0A), then only the 32BIT line item will be present in the output, as others have indicated in past answers. Otherwise 32BITREQ and 32BITPREF replace it.

这假设corflags.exe在%PATH%. exe文件中。确保这一点的最简单方法是使用开发人员命令提示符。或者，您也可以从默认位置复制它。

如果下面的批处理文件是针对一个非托管DLL或EXE文件运行的，它将错误地显示为x86，因为Corflags.exe的实际输出将是一个类似于:

CF008:指定的文件没有有效的托管头

@echo off

echo.
echo Target architecture for all exes and dlls:
echo.

REM For each exe and dll in this directory and all subdirectories...

for /f %%b in (testfiles.txt) do (
    REM Dump corflags results to a text file
    corflags /nologo %%b > corflagsdeets.txt

   REM Parse the corflags results to look for key markers
   findstr /C:"PE32+">nul .\corflagsdeets.txt && (
      REM `PE32+` indicates x64
        echo %%~b = x64
    ) || (
      REM pre-v8 Windows SDK listed only "32BIT" line item,
      REM newer versions list "32BITREQ" and "32BITPREF" line items
        findstr /C:"32BITREQ  : 0">nul /C:"32BIT     : 0" .\corflagsdeets.txt && (
            REM `PE32` and NOT 32bit required indicates Any CPU
            echo %%~b = Any CPU
        ) || (
            REM `PE32` and 32bit required indicates x86
            echo %%~b = x86
        )
    )

    del corflagsdeets.txt
)

del testfiles.txt
echo.

JetBrains的DotPeek提供了一个快速简单的方法来查看msil(任何CPU)， x86和x64:

我喜欢ILSpy工具。它不仅显示了架构，还显示了目标框架:

// linq2db, Version=3.0.0.0, Culture=neutral, PublicKeyToken=e41013125f9e410a
// Global type: <Module>
// Architecture: AnyCPU (64-bit preferred)
// Runtime: v4.0.30319
// This assembly is signed with a strong name key.
// This assembly was compiled using the /deterministic option.
// Hash algorithm: SHA1

因此，可以确定它是。net Core 2.1， .NET Framework 4.6或任何其他版本:

你自己写就行了。PE架构的核心自从在Windows 95中实现以来就没有发生过重大变化。

下面是一个c#的例子:

    public static ushort GetPEArchitecture(string pFilePath)
    {
        ushort architecture = 0;
        try
        {
            using (System.IO.FileStream fStream = new System.IO.FileStream(pFilePath, System.IO.FileMode.Open, System.IO.FileAccess.Read))
            {
                using (System.IO.BinaryReader bReader = new System.IO.BinaryReader(fStream))
                {
                    // Check the MZ signature
                    if (bReader.ReadUInt16() == 23117)
                    {
                        // Seek to e_lfanew.
                        fStream.Seek(0x3A, System.IO.SeekOrigin.Current);

                        // Seek to the start of the NT header.
                        fStream.Seek(bReader.ReadUInt32(), System.IO.SeekOrigin.Begin);

                        if (bReader.ReadUInt32() == 17744) // Check the PE\0\0 signature.
                        {
                            // Seek past the file header,
                            fStream.Seek(20, System.IO.SeekOrigin.Current);

                            // Read the magic number of the optional header.
                            architecture = bReader.ReadUInt16();
                        }
                    }
                }
            }
        }
        catch (Exception) { /* TODO: Any exception handling you want
                                     to do, personally I just take 0
                                     as a sign of failure */
        }

        // If architecture returns 0, there has been an error.
        return architecture;
    }
}

现在的常数是:

0x10B - PE32  format.
0x20B - PE32+ format.

但是用这种方法，它允许新常数的可能性。只要验证你认为合适的返回。
