可以看到我机器上面32Bit的.NET Framework 2.0 RTM版本里面的System.DLL是对应v2.0.50727版本的，属于PE32文件，是IL Only，不是32Bit的，因此这个是用AnyCPU来编译的。Corflags = 9 = COMIMAGE_FLAGS_ILONLY (1) + COMIMAGE_FLAGS_STRONGNAMESIGNED (8)

可以看到用/CLR编译选项编译出来的C++/CLI的代码总是混合的，因此是 ILONLY=0，值得注意的是其32BIT=0，说明当ILONLY=0的时候，CLR不需要32BIT=0就可以判断出这个PE32文件必然要在32BIT下面运行。
