数据类型转换之 CTime与CString

CTime 和CString的互相转换

CTime的格式有三种  short date:1990-10-10  long date:1990年10月1日  time: 8:30:10

引用  MSDN中CTime转换为CString  // example for CTime::Format and CTime::FormatGmt  CTime t( 1999, 3, 19, 22, 15, 0 );  // 10:15PM March 19, 1999  CString s = t.Format( “%A, %B %d, %Y” );  ASSERT( s == “Friday, March 19, 1999” );

时间的几种输出格式，其它格式要求见MSDN的strftime, wcsftime

//时间转字符  str = t.Format( “%A, %B %d, %Y” );//返回的是Wednesday,Jnuary 01,1992  //或者  str = t_birth.Format(VAR_DATEVALUEONLY);//1993-01-01  str =t.Format( “%x” ); //01/01/89  str = t.Format( “%X” ); //00:00:00  str = t.Format( “%Y年%m月%d日”);//1990年01月02日  str = t.Format( “%#Y年%#m月%#d日”);//1990年1月2日  str = t.Format( “%d年d月d日”,t.GetYear(),t.GetMonth(),  t.GetDay);());//1990年 1月 2日
