Calculate time Difference code in C # in asp.net

The easiest way for me to use it

The code is as follows	Copy Code
DateTime Dtone = Convert.todatetime ("2007-1-1 05:32:22"); DateTime dtwo = Convert.todatetime ("2007-1-1 04:20:15"); TimeSpan span = Dtone. Subtract (dtwo); Response.Write (span. Days + "Day" + span. Hours + "H" + span. Minutes + "Minutes" + span. seconds+ "seconds");

The above is given two times, the calculation time difference, the output is similar to "10 days 5 hours 10 minutes 28 seconds" format, but if I want to work out two pages to perform the slack.

Instance 1

The code is as follows

Copy Code

<summary> Program Execution Time Test </summary> <param name= "Datebegin" > Start time </param> <param name= "DateEnd" > End time </param> <returns> return (seconds) unit, for example: 0.00239 sec </returns> public static string Execdatediff (DateTime datebegin, datetime dateend) { TimeSpan ts1 = new TimeSpan (datebegin.ticks); TimeSpan ts2 = new TimeSpan (dateend.ticks); TimeSpan Ts3 = ts1. Subtract (TS2). Duration (); The format you want to turn Return Ts3. Totalmilliseconds.tostring (); }

This is the most basic and gets the number of milliseconds

If you're just a simple need for that format, you can just take the first 10 digits.

The code is as follows	Copy Code
1.ts3. ToString ("G") 0:00:07.171 2.ts3. ToString ("C") 00:00:07.1710000 3.ts3. ToString ("G") 0:00:00:07.1710000

There are three formats to choose from, and I suggest that you can use the Intercept test faster if you need one.
Like what

The code is as follows	Copy Code
Ts3. ToString ("G"). Substring (0,8) 0:00:07.1 Ts3. ToString ("C"). Substring (0,8) 00:00:07 Ts3. ToString ("G"). Substring (0,8) 0:00:00

Using TimeSpan in C # to calculate the difference of two times

code is as follows

copy code

can be added to any one time between two dates Between units. Private String DateDiff (DateTime DateTime1, datetime DateTime2) {string DateDiff = null; TimeSpan ts1 = new TimeSpan (datetime1.ticks); TimeSpan ts2 = new TimeSpan (datetime2.ticks); TimeSpan ts = ts1. Subtract (TS2). Duration (); DateDiff = ts. Days.tostring () + "days" + TS. Hours.tostring () + "hour" + TS. Minutes.tostring () + "minutes" + TS. Seconds.tostring () + "seconds"; return DateDiff; } TimeSpan ts = date1-date2; Double ddays = ts. totaldays;//number of days with decimals, such as 1 days 12 hours result is 1.5 int ndays = ts. days;//integer days, 1 days 12 hours or 1 days 20 hours results are 1

Functions of the last Published time

The code is as follows

Copy Code

public string Datestringfromnow (DateTime dt) { TimeSpan span = Datetime.now-dt; if (span. Totaldays > 60) { Return dt. ToShortDateString (); } else if (span. Totaldays > 30) { return "1 months ago"; } else if (span. Totaldays > 14) { Return "2 weeks ago"; } else if (span. Totaldays > 7) { Return "1 weeks ago"; } else if (span. Totaldays > 1) { return string. Format ("{0} days ago", (int) Math.floor (span). Totaldays)); } else if (span. Totalhours > 1) { return string. Format ("{0} hours ago", (int) Math.floor (span). totalhours)); } else if (span. Totalminutes > 1) { return string. Format ("{0} minutes ago", (int) Math.floor (span). totalminutes)); } else if (span. TotalSeconds >= 1) { return string. Format ("{0} seconds ago", (int) Math.floor (span). TotalSeconds)); } Else { Return "1 seconds ago"; } }
