Asp. Application of TimeSpan in net-practical skills

This article illustrates the usage of timespan in asp.net and share it for everyone's reference. Specifically as follows:

In ASP.net, two times subtract, get a TimeSpan instance, TimeSpan have some attributes: Days, Totaldays, Hours, Totalhours, Minutes, Totalminutes, Seconds, TotalSeconds, Ticks, note that there is no totalticks.

First, TimeSpan constants, fields

Copy Code code as follows:

TimeSpan.MaxValue; 10675199.02:48:05.4775807
Timespan.minvalue; -10675199.02:48:05.4775808
TimeSpan.Zero; 0.00:00:00.0
Timespan.ticksperday; Number of Tick a day: 864000000000
Timespan.ticksperhour; Number of Tick in one hour: 36000000000
Timespan.tickspermillisecond; Number of Tick in a millisecond: 10000
Timespan.ticksperminute; Number of Tick in one minute: 600000000
Timespan.tickspersecond; Number of Tick in a second: 10000000

Second, TimeSpan static method

Copy Code code as follows:

Timespan.compare (); Contrast
Timespan.equals (); //=
Timespan.fromdays (); Build from Days
Timespan.fromhours (); Set up from a small number of hours
Timespan.frommilliseconds (); Based on the number of milliseconds
Timespan.fromminutes (); Set up from minute count
Timespan.fromseconds (); Set from number of seconds
Timespan.fromticks (); Establish from Tick number
Timespan.parse (); Build from String
Timespan.parseexact (); Creates a string from a specified format
Timespan.tryparse (); Attempt to build from string
Timespan.tryparseexact (); Attempt to create a string from a specified format

Third, TimeSpan properties

Copy Code code as follows:

Days; Day part Hours; Hours section
milliseconds; Millisecond section
Minutes; Sub-section
Seconds; Seconds part
Ticks; Total Tick
Totaldays; Total Days
totalhours; Total number of hours
TotalMilliseconds; Total number of milliseconds
Totalminutes; Total number of minutes
TotalSeconds; Total number of seconds

Four, TimeSpan method

Copy Code code as follows:

ADD (); + CompareTo (); Compared to
Duration (); Absolute
Equals (); //
Negate (); Take counter, + >-、-> +
Subtract (); -, the counter manipulation of ADD ()
ToString (); Formatted to a string,. Net 4.0 changes compared to previous versions

V. TimeSpan building Objects

Copy Code code as follows:

protected void Button1_Click (object sender, EventArgs e)
{
TimeSpan T1 = new TimeSpan (864000000000); 1.00:00:00
TimeSpan t2 = new TimeSpan (23, 59, 59); 23:59:59
TimeSpan t3 = new TimeSpan (30, 23, 59, 59); 30.23:59:59
TimeSpan T4 = new TimeSpan (30, 23, 59, 59, 999); 30.23:59:59.9990000

Double F = 365.25;
TimeSpan T5 = timespan.fromdays (f); 365.06:00:00
TimeSpan T6 = timespan.fromhours (f * 24); 365.06:00:00
TimeSpan t7 = Timespan.fromminutes (f * 24 * 60); 365.06:00:00
TimeSpan T8 = Timespan.fromseconds (f * 24 * 60 * 60); 365.06:00:00
TimeSpan T9 = Timespan.frommilliseconds (f * 24 * 60 * 60 * 1000); 365.06:00:00
TimeSpan t0 = timespan.fromticks ((long) (f * 24 * 60 * 60 * 1000 * 10000)); 365.06:00:00

TextBox1.Text = string. Format (' {0}\\n{1}\\n{2}\\n{3}\\n{4}\\n{5}\\n{6}\\n{7}\\n{8}\\n{9} ',
T1, T2, T3, T4, T5, T6, T7, T8, T9, t0
);
}

Vi. Examples of TimeSpan

Time 1 is 2010-1-2 8:43:35;
Time 2 is 2010-1-12 8:43:34.

With time 2 minus time 1, get a TimeSpan instance.

Then 2 times 1 more 9 days 23 hours 59 minutes 59 seconds.

Then, days is 9,hours is 23,minutes is 59,seconds is 59.

To see Ticks,tick is a time period, indicating 100 nanoseconds, that is, one out of 10,000 seconds, then Ticks here to indicate the total difference between the number of periods, namely: 9 * 24 * 3600 * 10000000 + 23 * 3600 * 10000000 + 59 * 60 * 10000000 + 59 * 10000000 = 8639990000000. 3600 is the number of seconds in an hour.

Totaldays is the Ticks conversion own number, namely: 8639990000000/(10000000 * 24 * 3600) = 9.99998842592593.

Totalhours is the conversion of Ticks into hours, that is: 8639990000000/(10000000 * 3600) = 239.999722222222.

Totalminutes is the conversion of Ticks into minutes, that is: 8639990000000/(10000000 * 60) = 14399.9833333333.

TotalSeconds is the conversion of Ticks into seconds, that is: 8639990000000/(10000000) = 863999.

I hope this article will help you with the ASP.net program design.
