ASP. Usage example resolution of TimeSpan in NET

This article illustrates the use of TimeSpan in ASP.NET, and share it with you for your reference. The details are as follows:

TimeSpan has several attributes: Days, TotalDays, Hours, TotalHours, Minutes, TotalMinutes, Seconds, TotalSeconds, Ticks. Note that there is no TotalTicks.

1. TimeSpan constants and fields

TimeSpan.MaxValue;            // 10675199.02:48:05.4775807

TimeSpan.MinValue;            //-10675199.02:48:05.4775808

TimeSpan.Zero;                //        0.00:00:00.0

TimeSpan.TicksPerDay;         //1 Days of    Tick  The number : 864000000000

TimeSpan.TicksPerHour;        //1 Hours of  Tick  The number : 36000000000

TimeSpan.TicksPerMillisecond; //1 ms  Tick  The number : 10000

TimeSpan.TicksPerMinute;      //1 Minutes of the  Tick  The number : 600000000

TimeSpan.TicksPerSecond;      //1 The second  Tick  The number : 10000000

2. TimeSpan static methods

TimeSpan.Compare();          // contrast 

TimeSpan.Equals();           //=       

TimeSpan.FromDays();         // Build from day to day 

TimeSpan.FromHours();        // Set up small hours 

TimeSpan.FromMilliseconds(); // Build from milliseconds 

TimeSpan.FromMinutes();      // Build from minutes 

TimeSpan.FromSeconds();      // From the number of seconds 

TimeSpan.FromTicks();        // from  Tick  For establishing 

TimeSpan.Parse();            // Build from string 

TimeSpan.ParseExact();       // Creates from a string in the specified format 

TimeSpan.TryParse();         // Attempt to build from a string 

TimeSpan.TryParseExact();    // Attempts to create a string from the specified format 

3. TimeSpan properties

Days;              // Some day  Hours; // Hours part 

Milliseconds;      // Ms part 

Minutes;           // Part points 

Seconds;           // Second part 

Ticks;             //Tick  The total number of 

TotalDays;         // The total number of days 

TotalHours;        // The total number of hours 

TotalMilliseconds; // The total number of milliseconds 

TotalMinutes;      // The total number of minutes 

TotalSeconds;      // The total number of seconds 

4. TimeSpan method

Add();       // + CompareTo(); // than 

Duration();  // The absolute value 

Equals();    //

Negate();    // The not , + > - , - > +

Subtract();  // -, Add() The manipulation 

ToString();  // Format to a string , .Net 4.0  This is a change from previous versions 

5. ES46en builds objects

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

        );

}

6. TimeSpan instance

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

Subtract time 1 from time 2 to obtain an instance of TimeSpan.

So time 2 is 9 days, 23 hours, 59 minutes and 59 seconds longer than time 1.

So, Days is 9, Hours is 23, Minutes is 59, Seconds is 59.

Let's look at Ticks again. Tick is one timing cycle, which means one hundred nanosecond, which means one ten millionth of a second. So Ticks here represents how many total time cycles are different, 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 to convert Ticks into days, that is: 8639990000000 / (10000000 * 24 * 3600) = 9.99998842592593.

TotalHours is to convert Ticks into hours, that is: 8639990000000 / (10000000 * 3600) = 239.999722222222.

TotalMinutes is to convert Ticks into minutes, that is: 8639990000000 / (10000000 * 60) = 14399.9833333333.

ES86en is to convert ES87en into seconds, that is: 8639990000000 / (10000000) = 863999.

I hope this article is helpful to your asp.net program design.
