CString 类型变量怎样就进行日期比较？

Question

CString aa={"2001-10-10"};
CString bb=={"2001-10-08"};
我想运行aa<bb+10;
判断aa是否小于bb+10天。怎样实现呀？

Answer 1

把aa bb都转化成CTime，把10转化成CTimeSpan，然后比较

Answer 2

能具体写一下吗？我的msdn坏了，查不了

Answer 3

CString aa="2002-10-13";
int iYear=atoi(aa.Mid(0,4));
int iMon=atoi(aa.Mid(5,2));
int iDay=atoi(aa.Mid(8,2));
CTime time1(iYear,iMon,iDay);
CString bb="2002-10-02";
iYear=atoi(bb.Mid(0,4));
iMon=atoi(bb.Mid(5,2));
iDay=atoi(bb.Mid(8,2));
CTime time2(iYear,iMon,iDay);
CTimeSpan ts(10,0,0,0);
if(time1>time2+ts)
{ }

Answer 5

CTime构造函数有六个参数，不好意思
CString aa="2002-10-13";
int iYear=atoi(aa.Mid(0,4));
int iMon=atoi(aa.Mid(5,2));
int iDay=atoi(aa.Mid(8,2));
CTime time1(iYear,iMon,iDay,0,0,0);
CString bb="2002-10-02";
iYear=atoi(bb.Mid(0,4));
iMon=atoi(bb.Mid(5,2));
iDay=atoi(bb.Mid(8,2));
CTime time2(iYear,iMon,iDay,0,0,0);
CTimeSpan ts(10,0,0,0);
CTime sdf=time2+ts;
if(time1>time2+ts)
{
int aaa=1;
}
