Question

如何將一個DateTime轉換爲ticks？

Answer 1

通過使用Ticks屬性：

DateTime now = DateTime.Now; 
long ticks = now.Ticks; 

Answer 2

static long ConvertDateTimeToTicks(DateTime datetime) 
    { 
     long ticks=datetime.Ticks; 
     return ticks; 
    } 

    static DateTime ConvertTicksToDateTime(long ticks) 
    { 
     DateTime datetime= new DateTime(ticks); 
     return datetime; 
    }
