最近在自学解析PE文件，根据小辣椒（CFF Explorer）以及各论坛上大佬的帖子，做了个黑屏打印PE文件的，历时7天完成，在此想跟有相关需要的同学们分享下思路，有不足之处也希望大家不吝赐教，指点出来。谢谢。
PE文件主要有DOS头，NT头（包含PE头，可选PE头，可选PE头中又包含着一个数据目录，里面包含了其他表单的RVA和大小），节表
表单主要有导出表，导入表，重定位表，资源表。除了资源表外，其他表单的各项数据都用代码实现了打印。
首先通过CreateFile打开文件，获得文件句柄，随后调用CreateFileMapping生成内存映射对象，再调用MapViewOfFile获得文件映射基址。
DOS头RVA=（IMAGE_DOS_HEADER）映射基址；
NT头RVA=（IMAGE_NT_HEADERS)DOS头+DOS头->e_lfanew的值；
PE头RVA=&（(IMAGE_FILE_HEADER)NT头->FileHeader);
可选PE头RVA=&（(IMAGE_OPTIONAL_HEADER)NT头->OptionalHeader);
节表RVA=IMAGE_FIRST_SECTION（NT头）；//节表的位置=DOS头大小（确定）+标准PE头大小（确定）+可选PE头大小（标准PE头的成员.SizeOfOptionalHeader记录了可选PE头大小）
节表数量：PE头->NumberOfSections;
导入表、导出表、重定位表的RVA和长度分别在可选PE头的->DataDirectory的第三、第一、第六个数组当中的VirtualAddress和size成员中（注意数组索引从0开始）
注意，在解析前，先要判断当前文件是否为PE文件：以下2个条件缺一不可。
1.dos头的值，即dos->e_magic是否等于0x5A4D（MZ）
2.NT头，即DOS头（RVA）+DOS->e_lfnew的值 得到的即为NT头的RVA 查看NT头的值，即NT->signatrue的值是否为0x00004550（PE）
下面po上代码：
