Asp. Use of TimeSpan in net

In ASP. NET, subtract two times, get a TimeSpan instance, TimeSpan has some properties: Days, Totaldays, Hours, TotalHours, Minutes, Totalminutes, Seconds, TotalSeconds, Ticks, note that there is no totalticks.

One, TimeSpan constants, fields

TimeSpan. MaxValue;//10675199.02:48:05.4775807
TimeSpan. MinValue;//-10675199.02:48:05.4775808
TimeSpan. Zero;//0.00:00:00.0
TimeSpan. Ticksperday;//Tick of the day: 864000000000
TimeSpan. Ticksperhour;Tick count per hour: 36000000000
TimeSpan. Tickspermillisecond;number of ticks per millisecond: 10000
TimeSpan. Ticksperminute;Tick count for one minute: 600000000
TimeSpan. Tickspersecond;Tick count for one second: 10000000

Second, TimeSpan static method

TimeSpan. Compare ();//Contrast
TimeSpan. Equals ();//=       
TimeSpan. Fromdays ();//Build from Days
TimeSpan. Fromhours ();//Set up from a small number of hours
TimeSpan. Frommilliseconds ();//From the number of milliseconds established
TimeSpan. Fromminutes ();//From the number of minutes established
TimeSpan. FromSeconds ();//From the number of seconds established
TimeSpan. Fromticks ();//Build from Tick count
TimeSpan. Parse ();//From string creation
TimeSpan. ParseExact ();//Create a string from the specified format
TimeSpan. TryParse ();//Try to build from a string
TimeSpan. TryParseExact ();//Try to create a string from the specified format

Third, TimeSpan Property

Days;//Day partHours;//hour part
Milliseconds;//Millisecond Section
Minutes;//Sub-section
Seconds;//Sec 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

ADD (); // + CompareTo (); //Compare to
Duration (); //Absolute value
Equals (); //
Negate (); //reverse, + >-、-> +
Subtract (); //-, anti-manipulation of ADD ()
ToString (); //formatted to string,. Net 4.0 changes compared to previous versions

 C # code replication

Protected voidButton1_Click (Objectsender, EventArgs e){TimeSpan T1= NewTimeSpan (864000000000);//1.00:00:00TimeSpan T2= NewTimeSpan (23,59,59);//23:59:59TimeSpan T3= NewTimeSpan (30,23,59,59);//30.23:59:59TimeSpan T4= NewTimeSpan (30,23,59,59,999);//30.23:59:59.9990000 DoubleF= 365.25; TimeSpan T5=Timespan.fromdays (f);//365.06:00:00TimeSpan T6=Timespan.fromhours (f* 24);//365.06:00:00TimeSpan T7=Timespan.fromminutes (f* 24 * 60);//365.06:00:00TimeSpan T8=Timespan.fromseconds (f* 24 * 60 * 60);//365.06:00:00TimeSpan T9=Timespan.frommilliseconds (f*    *   [  *   +   *   + ]; // 365.06:00:00   TimeSpan t0  =  timespan.fromticks (( long ) (F  *     *   $   *   $   *   +   *   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);}                  /span>                 

Vi. instances of TimeSpan

C # codeCopy

Time1Is2010-1-2 8:43:35; time2Is2010-1-12 8:43:34。 Use time2Time reduction1, you get a TimeSpan instance. So time2than time1Many9Days23Hours59Score of59Seconds. So, Days is9, Hours is23, Minutes is59, Seconds is59。 Look againTicks, Tick is a chronograph that represents 100 nanoseconds, or one out of 10,000 seconds, so Ticks here indicates how many time periods are different in total, namely:9 * 24 * 3600 * 10000000 + 23 * 3600 * 10000000 + 59 * 60 * 10000000 + 59 * 10000000 = 8639990000000。3600Is the number of seconds in an hour.totaldaysis to convert Ticks to Rewardcash octopus number, i.e.:8639990000000 /(10000000  *   [  *   3600 ]  =   9.99998842592593 .  TotalHours  translates Ticks into hours, that is:  8639990000000  / ( 10000000   *   3600 )  =   239.999722222222 .  Totalminutes  is the conversion of Ticks into minutes, that is:  8639990000000  / ( 10000000   *   )  =   14399.9833333333 .  TotalSeconds  is the conversion of Ticks into seconds, i.e.  8639990000000  / ( 10000000 )  =   863999 .
