MFC中一行一行地读文件

1、方法1：

CStdioFile file;
CString strContent;
CString temp;
char* old_locale = _strdup( setlocale(LC_CTYPE,NULL) );
setlocale( LC_CTYPE, "chs" ); 
if(NULL != file.Open(path.GetBuffer(), CFile::modeRead))
{
	while (file.ReadString(temp))
	{
	               strContent += temp;
		strContent += "\n";
	}
	file.Close();
}
else
{
	AfxMessageBox(L"文件打开失败");
}
setlocale( LC_CTYPE, old_locale ); 
free( old_locale );

 2、方法2

CFile file;
char strLine[505];
CString strContent;
f(NULL != file.Open(path.GetBuffer(), CFile::modeRead))
{
	int len = 0;
	CString temp;
	
	while ((len = file.Read(strLine, 500)) )
	{
		strLine[len] = '\0';
		strContent += strLine;
	}
	file.Close();
}
else
{
	AfxMessageBox(_T("文件打开失败"));
}
