要在“导入目录表”中读取库的名称,可以执行以下操作：

>获取文件的内存映射基址.
>获取指向IMAGE_NT_HEADERS结构的指针.
>获取指向IMAGE_SECTION_HEADER结构的指针.
> DataDirectory是OptionalHeader的最后128个字节,而后者又是PE头IMAGE_NT_HEADERS的最终成员.
该结构有2个成员,包含数据结构的位置和大小.
如果要查找有关dll名称的信息,首先要从数据目录中找到导入目录的RVA(相对虚拟地址),在原始部分数据中找到该地址,现在您有一个IMAGE_IMPORT_DESCRIPTOR数组.通过检查Name字段指向的字符串,获取与映射图像相关的此数组的成员.

我不会描述可移植可执行文件格式的结构,但您可以查看以下链接：
