DecodeTime - C++ Builder

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


从日期时间类型数值里面解析出时、分、秒、毫秒

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

void __fastcall DecodeTime(const System::TDateTime DateTime, System::Word &Hour, System::Word &Min, System::Word &Sec, System::Word &MSec);

参数:

  • DateTime:日期时间类型变量;
  • Hour:返回时,0 ~ 23;
  • Min:返回分,0 ~ 59;
  • Sec:返回秒,0 ~ 59;
  • MSec:返回毫秒,0 ~ 999;

返回值:

  • 无,解析结果通过参数 Hour, Min, Sec, MSec 返回。

例:

void __fastcall TForm1::Button1Click(TObject *Sender)
{
    System::TDateTime dt = Sysutils::Now();
    unsigned short uHour, uMin, uSec, uMSec;
    Sysutils::DecodeTime(dt, uHour, uMin, uSec, uMSec);
    UnicodeString s;
    s.sprintf(L"现在时间是 %d:%02d:%02d.%03d", uHour, uMin, uSec, uMSec);
    Memo1->Lines->Add(s);
}
