如何读取第一行28 赋给a
读取第二行 56 赋给 b?

[jeff_5388]

CStdioFile file1;
file1.Open(pFileName,CFile::modeRead);
CString s1, s2;
file1.ReadString(s1);
a = atoi(s1);
file1.ReadString(s2);
b = atoi(s2);

读取文件有一个起始指针和结尾指针，你把起始指针移动相应的位置，再读。

char* pFileName = "1.txt";
CStdioFile file1;
file1.Open(pFileName,CFile::modeRead);
char buf1[2],buf2[2];
file1.SeekToBegin();
file1.ReadString(buf1);
file1.Seek(2,CFile::end);
file1.ReadString(buf2);

CStdioFile::ReadString(),一行一行的读。
