timespan

问题 How can I use the value of a TimeSpan as the interval for a Timer ? 回答1: Get the total milliseconds from the TimeSpan to use in the constructor for Timer: var timer = new Timer(someTimeSpanObject.TotalMilliseconds); 回答2: From: http://msdn.microsoft.com/en-us/library/system.timespan.totalmilliseconds.aspx TimeSpan interval = new TimeSpan(1, 15, 42, 45, 750); Console.WriteLine("Value of TimeSpan: {0}", interval); Console.WriteLine("{0:N5} seconds, as follows:", interval.TotalMilliSeconds); You

问题 I have the following table: SHIFT ---------------------------------------- | SHIFT_ID | SHIFT_TIME | SHIFT_DURATION | | -------------------------------------- | | 1 | 00:00:00 | 01:00:00 | | 2 | 01:00:00 | 01:00:00 | | 3 | 02:00:00 | 01:00:00 | ---------------------------------------- Here, SHIFT_TIME and SHIFT_DURATION are of type TimeSpan . Now, when I run the following query: var query = from c in SHIFT where c.SHIFT_TIME + c.SHIFT_DURATION >= new TimeSpan(DateTime.Now.Hour, DateTime.Now

问题 I am bringing back time values from a record set into an RDLC report. (c# Visual Studio 2013) They are coming is as a nullable Timespan. Which i display as HH:MM This all looks fine until i get a null , if there is no time for record a null is returned,as it's a nullable timespan type. When this happens i get an #error in the RDLC report. What i want to happen is either show "00:00" , or just blank. I have tried adding an IFF to the Expression field in RDLC so that if a null is returned i

问题 I'm currently trying to multibind a WPF TextBlock to a TimeSpan property. The following works: <TextBlock HorizontalAlignment="Right" VerticalAlignment="Center" Text="{Binding Path=ImportOperationRuntime, StringFormat='hh\\:mm\\:ss'}" /> Unfortunately, using a MultiBinding "destroys" the StringFormat and displays the milliseconds alongside (though hidden through the StringFormat). The following ones do not work: <TextBlock Grid.Column="6" VerticalAlignment="Center"> <TextBlock.Text>

问题 I have a modal dialog in my web application where users are able to enter a time range between 00:00 and 24:00. A range slider is used to select this range. Everything works as expected except that whenever user sets the right range handle to have a value of 24:00 default model binder can't parse this TimeSpan . public class Timing { public TimeSpan Starts { get; set; } public TimeSpan Ends { get; set; } } My object that gets sent back to server has an IList<Timing> property. So. The problem

问题 I have a bit of a unique problem in that my quartz job scheduler implementation which build using the quartz.net code base ver 2.0.1, recently discovered that the time zone and utc offsets are being ignored while running and executing jobs. This is an inherit bug in this version of quartz.net and updating to version 2.1.1 is out of scope right now, so I wrote a quick and dirty way of calculating the offset using this algorithm: (ServerTime - ClientTime) - TargetTime = New_TargetTime_With

问题 I have the following two time column,"Time1" and "Time2".I have to calculate the "Difference" column,which is (Time2-Time1) in Pandas: Time1 Time2 Difference 8:59:45 9:27:30 -1 days +23:27:45 9:52:29 10:08:54 -1 days +23:16:26 8:07:15 8:07:53 00:00:38 When Time1 and Time2 are in different hours,I am getting result as"-1 days +" .My desired output for First two values are given below: Time1 Time2 Difference 8:59:45 9:27:30 00:27:45 9:52:29 10:08:54 00:16:26 How can I get this output in Pandas?

问题 I have to create a real time report. For that, I have to write conditions for each and every hour of a given day. In the code below, the condition checks for the current day of week and then check for the current time and based on that a report has to be generated. protected void sample() { TimeSpan zerothHour = new TimeSpan(00, 0, 0); TimeSpan firstHour = new TimeSpan(01, 0, 0); TimeSpan secondHour = new TimeSpan(02, 0, 0); TimeSpan thirdHour = new TimeSpan(03, 0, 0); TimeSpan fourthHour =

问题 Excuse the rough code, I'm trying to display the duration of videos given the time in seconds. I've had a go below but it's not working properly. I want it to just display nicely - i.e should display 9m:59s not 09m:59s. If hours are zero dont display hours, if minutes are zero dont display minutes. public static string GetTimeSpan(int secs) { TimeSpan t = TimeSpan.FromSeconds(secs); string answer; if (secs < 60) { answer = string.Format("{0:D2}s", t.Seconds); } else if (secs < 600)//tenmins {

问题 I just want to add 1 day to a DateTime . So I wrote: DateTime date = new DateTime(2010, 4, 29, 10, 25, 00); TimeSpan t = new TimeSpan(1, 0, 0, 0); date.Add(t); Console.WriteLine("A day after the day: " + date.ToString()); I thought the result would be: 2010 04 30- 10:25:00 but I'm still getting the initial date. What's wrong? 回答1: DateTime values are immutable . The Add method returns a new DateTime value with the TimeSpan added. This works: Console.WriteLine("A day after the day: " + date
