What is the time type of C #
This article is about what the C# time type is. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.
C # time type is represented as datetime type
Define a datetime variable dt as follows: DateTimedt;//DateTime is the declaration of the C# time type, and dt is the name of the declared variable
One of the common mistakes to note is assigning a string to a datetime variable, for example, I want the defined variable dt to represent the 20:00:00 time. If written as dt= "20:00:00"; or dt= (DateTime) ("20:00:00")
This is all wrong because "20:00:00" here is a string, or string, and cannot be assigned to dt in the above way. The correct assignment method is: dt=Convert.ToDateTime ("20:00:00")
This assigns the time "20:00:00" to dt
Let's talk about the basics of the C# time type DateTime:
DateTimecurrentTime=newDateTime (); / / create a DateTime type variable currentTime,DateTime is the type and currentTime is the variable name
CurrentTime=System.DateTime.Now;// takes the current time: year, month, day, hour, minute and second
Int year = currentTime.Year;// current year (variable name can be in Chinese)
Int month = currentTime.Month;// current month
Int day = currentTime.Day;// current day
Int = currentTime.Hour;// current tense
Int score = currentTime.Minute;// current score
Int second = currentTime.Second;// current second
Int millisecond = currentTime.Millisecond;// current millisecond DateTimedt1=DateTime.Now
StringWeek=dt1.DayOfWeek;// indicates what day the current date is, and the return value is string (sunday,monday.)
StringDay=dt1.Day;// indicates that the current date is the day of the month, and the return value is int.
/ / there are other methods such as DayOfYear.
A simple function to judge two time intervals, with three parameters: DateTime1 and DateTime2 are the time to be compared, and Type is the unit of comparison. The C # time type function is as follows:
PrivatedoubleDateDiff (DateTimeDateTime1,DateTimeDateTime2,stringType)... {doubledateDiff=0; TimeSpants1=newTimeSpan (DateTime1.Ticks); TimeSpants2=newTimeSpan (DateTime2.Ticks); TimeSpants=ts1.Subtract (ts2). Duration (); switch (Type)... {case "d": dateDiff=ts.TotalDays; break; case "h": dateDiff=ts.TotalHours; break; case "m": dateDiff=ts.TotalMinutes; break; case "s": dateDiff=ts.TotalSeconds; break;} returndateDiff;}
For example, if the DateTime1 is 9 DateTime1 20 and the date time 2 is 10:30:20, call the function DateTimedt1=Convert.ToDateTime ("9:20:00")
DateTimedt2=Convert.ToDateTime ("10:30:20"); doubleday=DateDiff (dt1,dt2, "d"); doublehour=DateDiff (dt1,dt2, "h"); doublemin=DateDiff (dt1,dt2, "m"); doublesecond=DateDiff (dt1,dt2, "s"); day=0.04884259259259259;hour=1.1722222222222223;min=70.333333333333329;second=4220.0; available thank you for reading!
