一个工具是sigcheck:

sigcheck c:\Windows\winhlp32.exe

我克隆了一个超级方便的工具，它为Windows资源管理器中的程序集添加了一个上下文菜单项，以显示所有可用的信息:

从release·tebjan/AssemblyInformation下载。

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:

还有一种方法是在DLL上使用Visual Studio工具中的dumpbin，并寻找适当的输出:

dumpbin.exe /HEADERS <your DLL file path>
    FILE HEADER VALUE
                 14C machine (x86)
                   4 number of sections
            5885AC36 time date stamp Mon Jan 23 12:39:42 2017
                   0 file pointer to symbol table
                   0 number of symbols
                  E0 size of optional header
                2102 characteristics
                       Executable
                       32 bit word machine
                       DLL

注意:上面的输出是一个32位DLL文件

dumpbin.exe的一个更有用的选项是/EXPORTS。它将显示DLL文件公开的函数

dumpbin.exe /EXPORTS <PATH OF THE DLL FILE>

试着在CodePlex中使用这个项目中的CorFlagsReader。它没有对其他程序集的引用，可以按原样使用。
