EXE文件和DLL文件同样是PE文件结构,那如何区别它们呢? ( 积分: 50 )

如题...<br>PS:不要和我说用单纯的判断文件扩展名方法...^_^

Function&nbsp;IsDll(FileName&nbsp;:&nbsp;String):Boolean;<br>var<br>&nbsp;&nbsp;hFile&nbsp;:&nbsp;THandle;<br>&nbsp;&nbsp;Mem&nbsp;:&nbsp;TMemoryStream;<br>&nbsp;&nbsp;DosHeader&nbsp;:&nbsp;PImageDosHeader;<br>&nbsp;&nbsp;NtHeader&nbsp;:&nbsp;PImageNtHeaders;<br>begin<br>&nbsp;&nbsp;Result&nbsp;:=&nbsp;False;<br>&nbsp;&nbsp;Mem&nbsp;:=&nbsp;TMemoryStream.Create;<br>&nbsp;&nbsp;Mem.LoadFromFile(FileName);<br>&nbsp;&nbsp;DosHeader&nbsp;:=&nbsp;PImageDosHeader(Mem.Memory);<br>&nbsp;&nbsp;NtHeader&nbsp;:=&nbsp;PImageNtHeaders(PChar(DosHeader)&nbsp;+&nbsp;DosHeader^._lfanew);<br>&nbsp;&nbsp;Result&nbsp;:=&nbsp;((NtHeader^.FileHeader.Characteristics&nbsp;and&nbsp;IMAGE_FILE_DLL)=&nbsp;IMAGE_FILE_DLL);<br><br>&nbsp;&nbsp;Mem.Free;<br>end;
