虚拟偏移地址和文件物理偏移地址的计算公式如下：
>>>>>>>VaToFileOffset(虚拟地址转文件偏移地址)
如VA = 00401000 (虚拟地址)
ImageBase = 00400000 (基地址)
VRk = VOffset - ROffset = 00001000 - 00000400 (得出文件虚拟地址和文件物理址之间的VRk值)
FileOffset = VA - ImageBase - VRk = 00401000 - 00400000 - VRk = 400(文件物理地址的偏移地址)
如VA = 00401325，则：
FileOffset = VA - ImageBase - VRk = 00401325 - 00400000 - VRk = 725
>>>>>>FileOffsetToVa(文件偏移地址转虚拟地址)
如FileOffset = 435(文件偏移地址)
VA = FileOffset + ImageBase + VRk = 435 + 00400000 + VRk = 00401035(虚拟地址)
