C++ Builder 参考手册 ➙ System::Sysutils ➙ DecodeDate


从日期时间类型数值里面解析出年、月、日

头文件:#include
命名空间:System::Sysutils
函数原型:

void __fastcall DecodeDate(const System::TDateTime DateTime, System::Word &Year, System::Word &Month, System::Word &Day);

参数:

  • DateTime:日期时间类型变量;
  • Year:返回年,1 ~ 9999
  • Month:返回月,1 ~ 12
  • Day:返回日,1 ~ 31

返回值:

  • 无,解析结果通过参数 Year, Month, Day 返回。

例:

void __fastcall TForm1::Button1Click(TObject *Sender)
{
    System::TDateTime dt = Sysutils::Now();
    unsigned short uYear, uMonth, uDay;
    Sysutils::DecodeDate(dt, uYear, uMonth, uDay);
    UnicodeString s;
    s.sprintf(L"今天日期:%u 年 %u 月 %u 日", uYear, uMonth, uDay);
    Memo1->Lines->Add(s);
}

运行结果:
