文本与二进制内容的存取操作

int _tmain(int argc, TCHAR* argv[], TCHAR* envp[]){char s1[4] = "66";int n1 = 66;char s2[4];int n2;//writeCFile file;file.Open(_T("test.out"), CFile::modeWrite | CFile::modeCreate);file.Write(s1, sizeof(s1));file.Write(&n1, sizeof(n1));file.Close();//readfile.Open(_T("test.out"), CFile::modeRead);file.Read(s2, sizeof(s2));file.Read(&n2, sizeof(n2));printf("s2=%s/r/n", s2);printf("n2=%d/r/n", n2);file.SeekToBegin();file.Read(&n2, sizeof(n2));file.Read(s2, sizeof(s2));printf("s2=%s/r/n", s2);printf("n2=%d/r/n", n2);file.Close();return 0;} 

 

s2=66

n2=66

s2=B

n2=13878

请按任意键继续. . .

 

在读文件时，其顺序应该和写文件的顺序一致，否则会带来不可预测的错误
