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。”

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。

前面提到的一个替代工具是Telerik JustDecompile(免费工具)，它将在程序集名称旁边显示信息:

一个更通用的方法-使用文件结构来确定位和图像类型:

public static CompilationMode GetCompilationMode(this FileInfo info)
{
    if (!info.Exists)
        throw new ArgumentException($"{info.FullName} does not exist");

    var intPtr = IntPtr.Zero;
    try
    {
        uint unmanagedBufferSize = 4096;
        intPtr = Marshal.AllocHGlobal((int)unmanagedBufferSize);

        using (var stream = File.Open(info.FullName, FileMode.Open, FileAccess.Read))
        {
            var bytes = new byte[unmanagedBufferSize];
            stream.Read(bytes, 0, bytes.Length);
            Marshal.Copy(bytes, 0, intPtr, bytes.Length);
        }

        // Check DOS header magic number
        if (Marshal.ReadInt16(intPtr) != 0x5a4d)
            return CompilationMode.Invalid;

        // This will get the address for the WinNT header
        var ntHeaderAddressOffset = Marshal.ReadInt32(intPtr + 60);

        // Check WinNT header signature
        var signature = Marshal.ReadInt32(intPtr + ntHeaderAddressOffset);
        if (signature != 0x4550)
            return CompilationMode.Invalid;

        // Determine file bitness by reading magic from IMAGE_OPTIONAL_HEADER
        var magic = Marshal.ReadInt16(intPtr + ntHeaderAddressOffset + 24);

        var result = CompilationMode.Invalid;
        uint clrHeaderSize;
        if (magic == 0x10b)
        {
            clrHeaderSize = (uint)Marshal.ReadInt32(intPtr + ntHeaderAddressOffset + 24 + 208 + 4);
            result |= CompilationMode.Bit32;
        }
        else if (magic == 0x20b)
        {
            clrHeaderSize = (uint)Marshal.ReadInt32(intPtr + ntHeaderAddressOffset + 24 + 224 + 4);
            result |= CompilationMode.Bit64;
        }
        else return CompilationMode.Invalid;

        result |= clrHeaderSize != 0
            ? CompilationMode.CLR
            : CompilationMode.Native;

        return result;
    }
    finally
    {
        if (intPtr != IntPtr.Zero)
            Marshal.FreeHGlobal(intPtr);
    }
}

编译模式枚举

[Flags]
public enum CompilationMode
{
    Invalid = 0,
    Native = 0x1,
    CLR = Native << 1,
    Bit32 = CLR << 1,
    Bit64 = Bit32 << 1
}
