查看dll是32位还是64位

你可以用VS调用dumpbin并使用headers选项，例如：

dumpbin /headers my32bit.dll

输出：

PE signature foundFile Type: DLLFILE HEADER VALUES         14C machine (x86)           1 number of sections    45499E0A time date stamp Thu Nov 02 03:28:10 2006           0 file pointer to symbol table           0 number of symbols          E0 size of optional header        2102 characteristics               Executable               32 bit word machine               DLLOPTIONAL HEADER VALUES         10B magic # (PE32)
