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:

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。

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。

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:
