I have a program that suggests the time of day to leave to go hunting duck/goose hunting on time. It asks the users for the time of sunrise, how long the drive will take, etc and calculates what time you should leave to make it there on time. My program works but I need to format the results. Example: Sunrise of 7, drive of 30, setup of 30, walking of 30, waiting of 30 results as 4.5 (which is correct) but I want it to read as 4:30. Any Suggestions?? Please and thanks!
Console.WriteLine("Enter sunrise");//7AM would be 420minutes
double sunrise = Convert.ToInt32(Console.ReadLine());
double minutes = sunrise * 60;
double legal = 30;//allowed to shoot 30min before sunrise
Console.WriteLine("How many minutes will it take to drive to" +
"your destination: ");
double drive = Convert.ToInt32(Console.ReadLine());
Console.WriteLine("How many minutes will it take to set up: ");
double setup = Convert.ToInt32(Console.ReadLine());
Console.WriteLine("How many minutes will it take to walk from " +
"your vehicle to the actual hunting spot:");
double walking = Convert.ToInt32(Console.ReadLine());
Console.WriteLine("Amount of time between setting up and " +
"pulling the trigger:");
double waiting = Convert.ToInt32(Console.ReadLine());
double departure = ((minutes - (legal + drive + setup + walking
+ waiting))/60);//6.5
Console.WriteLine("If sunrise is at " + sunrise +"AM, and it
takes " + drive + " minutes to drive there you should leave at" +
departure + "AM");
Change your
double ... = Convert.ToInt32(Console.ReadLine());
To
TimeSpan ... = TimeSpan.FromMinutes(int.Parse(Console.ReadLine());
And then use:
TimeSpan departure = sunrise - (legal + drive + setup + waiting);
Console.WriteLine("If sunrise is at {0}AM, and it takes {1} minutes to drive there you should leave at {2}AM",
sunrise, drive.Minutes, departure);
You can then play with TimeSpan formatting until you get the desired output.
One way to do it would be to get the sunrise time as a Time format (hh:mm) from the user, and the other values as minutes. Then you can convert sunrise to a DateTime, subtract 30 minutes, and subtract the total of the rest of the times. This will leave you with a DateTime result, which is easy to format with AM/PM information.
To assist in getting valid input from the user, I would create the following two methods, which get a TimeSpan and an int from the user (along with necessary retries if they input incorrect data). Note that the one that gets a TimeSpan only expects the hours and minutes, and automatically adds :00 for the seconds:
private static TimeSpan GetTimeFromUser(string prompt)
{
Console.Write(prompt);
TimeSpan result;
while (!TimeSpan.TryParse(Console.ReadLine() + ":00", out result))
{
Console.WriteLine("Please use format hh:mm for the time.");
Console.Write(prompt);
}
return result;
}
private static int GetIntFromUser(string prompt)
{
Console.Write(prompt);
int result;
while (!int.TryParse(Console.ReadLine(), out result))
{
Console.WriteLine("Please enter a valid integer.");
Console.Write(prompt);
}
return result;
}
With those helper functions out of the way, we can get the info from the user pretty easily, and then display back the results:
private static void Main()
{
DateTime sunrise = DateTime.Today.Add(GetTimeFromUser("Enter sunrise time: "));
DateTime legalStartTime = sunrise.AddMinutes(-30);
int driveTime = GetIntFromUser(
"How many minutes will it take to drive to your destination: ");
int setupTime = GetIntFromUser(
"How many minutes will it take to set up: ");
int walkTime = GetIntFromUser(
"How many minutes will it take to walk from your vehicle to the hunting spot: ");
int waitTime = GetIntFromUser(
"Number of minutes between setting up and pulling the trigger: ");
int totalTime = driveTime + setupTime + walkTime + waitTime;
DateTime departureTime = legalStartTime.AddMinutes(-totalTime);
Console.WriteLine($"If sunrise is at {sunrise:hh:mm tt}, and it takes {totalTime} " +
$"minutes to drive and get ready, you should leave at: {departureTime:hh:mm tt}");
Console.WriteLine("\nDone!\nPress any key to exit...");
Console.ReadKey();
}
Output
DateTime.Today.AddHours(departure).ToLongTimeString()
Although few solutions were introduced, i felt the need to add more complete but naive solution, which will handle sunrise as DateTime and represent result as time.
Console.WriteLine("Sunrise at:");
var sunrise = DateTime.Parse(Console.ReadLine());
Console.WriteLine("How many minutes will it take to drive to your destination: ");
var drive = TimeSpan.FromMinutes(int.Parse(Console.ReadLine()));
Console.WriteLine("How many minutes will it take to set up: ");
var setup = TimeSpan.FromMinutes(int.Parse(Console.ReadLine()));
Console.WriteLine("How many minutes will it take to walk from your vehicle to the actual hunting spot:");
var walking = TimeSpan.FromMinutes(int.Parse(Console.ReadLine()));
Console.WriteLine("Amount of time between setting up and pulling the trigger:");
var waiting = TimeSpan.FromMinutes(int.Parse(Console.ReadLine()));
var legalTimeBeforeSunriseInMin = TimeSpan.FromMinutes(30);
var calculatedDelta = (legalTimeBeforeSunriseInMin + drive + setup + walking + waiting);
var departure = sunrise.Add(-calculatedDelta).ToLongTimeString();
Console.WriteLine($"If sunrise is at {sunrise.ToLongTimeString()}, and it takes {drive} minutes to drive there you should leave at {departure}");
double t = 4.5;
TimeSpan s = TimeSpan.FromMinutes(t * 60);
string result = s.ToString(#"h\:mm");
If you have a time in fractional hours like
var departTimeInHours = 4.5;
And you want to display it as a 12-hour time formatted string with colon and AM/PM, one possibility is to create a DateTime from the fractional hours and use that type's built-in string conversion, which has the advantage of being localized (are there non AM/PM localized time formats?). The simplest way to convert the fractional hours to a DateTime is to convert them to ticks (which are 100 nanosecond units) and then call the constructor.
var strDepartTime = (new DateTime((long)(departTimeInHours*60*60*10000000)).ToString("t");

I have to make a program that asks someone for their birthday and calculates when the next day is when they turn a multiple of 1000 days.
I made the following code already:
using System;
Console.WriteLine("welkom bij de verKdag calculator, vul de volgende getallen in:");
Console.WriteLine("wat is je geboortedag? ");
String s = Console.ReadLine();
int d = int.Parse(s);
Console.WriteLine("wat is je geboortemaand");
int m = int.Parse( Console.ReadLine() );
Console.WriteLine("wat is je geboortejaar");
int y = int.Parse(Console.ReadLine());
DateTime gebdat = new DateTime(y, m, d);
DateTime vandaag = DateTime.Today;
var diffofdates = vandaag.Subtract(gebdat);
Console.WriteLine(diffofdates);
Console.ReadLine();
Now< I need to figure out a way to find the closest multiple of 1000 to diffofdates and calculate which date corresponds to that, how do I do that?
Use the modulus operator to calculate the number of days remaining, and then use that to get the target date:
int daysRemaining = 1000 - (int)diffofdates.TotalDays % 1000;
DateTime targetDate = DateTime.Today.AddDays(daysRemaining);
Console.WriteLine("You'll reach a multiple of 1000 days " +
$"on {targetDate.ToShortDateString()} (in {daysRemaining} days from now)");
As a side note, consider using int.TryParse() instead of int.Parse() and validating that the user input is a valid date. Alternatively, you could use DateTime.TryParse() or (preferably) DateTime.TryParseExact() and allow the user to enter their date of birth in one go.
I'm making a funny discord bot that finds the next 4:20 on the clock, whether it's AM or PM, and tells you how long until 4:20. My code is working perfectly until an hour before 4:20 and then it skips ahead and tells how long until the next 4:20 instead of showing "0 hours 59 minutes". I'm thinking that there may be an issue with how I'm formatting the time output but I'm very new to C# and how no idea how to fix it. I have included my code and also a screenshot of the current output. In the screenshot the bot is also a minute off but I've since then figured out how to fix that. I know the code isn't the most efficient or clean but again, I'm very new to programming.
//Finds next 4:20 on the clock
[Command("420")]
public async Task WeedMinute()
{
DateTime currentTime = DateTime.Now; //Current time
DateTime weedMinuteMorning = Convert.ToDateTime("4:21:00"); //4:20am
DateTime weedMinuteEvening = Convert.ToDateTime("16:21:00"); //4:20pm
string weedMinutePM = "16:21:00"; //These variables are used in subtraction
string weedMinuteAM = "4:21:00";
if (currentTime <= weedMinuteEvening)
{
//chooseMorningEvening is the output time string
DateTime chooseMorningEvening = (DateTime.Parse(weedMinutePM).Subtract(currentTime.TimeOfDay));
await Context.Channel.SendMessageAsync("The next weed minute will happen in " + chooseMorningEvening.ToString(#"hh") + " hours " + chooseMorningEvening.ToString(#"mm") + " minutes.");
}
else if (currentTime >= weedMinuteMorning)
{
//chooseMorningEvening is the output time string
DateTime chooseMorningEvening = (DateTime.Parse(weedMinuteAM).Subtract(currentTime.TimeOfDay));
await Context.Channel.SendMessageAsync("The next weed minute will happen in " + chooseMorningEvening.ToString(#"hh") + " hours " + chooseMorningEvening.ToString(#"mm") + " minutes.");
}
}
The problem with your code is that it does not handle all the cases that can occur (there are three):
time is between 00:00:00 and 04:20:00 => calculate time to 04:20:00
time is between 04:20:00 and 16:20:00 => calculate time to 16:20:00
time is after 16:20:00 => calculate time to 04:20:00, next day.
You can simplify this a little if you observe that the time till your next toke should always be between 0 and 12 hours. So, if you just take the time until 16:20, if it is greater than 12 hours then you must be up before 04:20 and you can subtract 12 hours. If the time is less than 0 (that is, negative) then you must be later than 16:20 so you just add 12 hours. In code this looks like this:
public static TimeSpan CalculateTimeToWeed(DateTime from)
{
DateTime weedTime = Convert.ToDateTime("16:20:00");
TimeSpan twelveHours = TimeSpan.FromHours(12.0);
TimeSpan timeToWeed = weedTime - from;
double totalHours = timeToWeed.TotalHours;
if (totalHours > 12.0)
{
timeToWeed -= twelveHours;
}
else if (totalHours < 0.0)
{
timeToWeed += twelveHours;
}
return timeToWeed;
}
and you would integrate it into your Discord bot as follows:
[Command("420")]
public async Task WeedMinute()
{
DateTime currentTime = DateTime.Now;
TimeSpan timeToWeed = CalculateTimeToWeed(currentTime);
string message = "The next weed minute will happen in " + timeToWeed.ToString("hh' hours 'mm' minutes.'");
await Context.Channel.SendMessageAsync(message);
}
You could cut down the number of lines in this, but having these temporary variable makes thing easier to debug. You can check while stepping through with a debugger that currentTime is what you expect and timeToWeed makes sense and so on.
Breaking the code into two functions also has a number of advantages:
You can test the time calculation independent of the bot
The code is much clearer, you are not mixing up communication code with calculation code.
Hope this helps.
There's a DateTime.Compare function which can be used here to fix the error as below
//DateTime currentTime = DateTime.Now; //Current time
DateTime currentTime = Convert.ToDateTime("3:22:00"); // An example time for 0 hours and 59 mins
DateTime weedMinuteMorning = Convert.ToDateTime("4:21:00"); //4:20am
DateTime weedMinuteEvening = Convert.ToDateTime("16:21:00"); //4:20pm
string weedMinutePM = "16:21:00"; //These variables are used in subtraction
string weedMinuteAM = "4:21:00";
if(currentTime.CompareTo(weedMinuteMorning) < 1) //less than or same as Morning 4:20 am
{
var chooseMorningEvening = weedMinuteMorning - currentTime;
string m = "The next weed minute will happen in " + chooseMorningEvening.Hours + " hours " + chooseMorningEvening.Minutes + " minutes.";
}
else
{
var chooseMorningEvening = weedMinuteEvening - currentTime;
string m = "The next weed minute will happen in " + chooseMorningEvening.Hours + " hours " + chooseMorningEvening.Minutes + " minutes.";
}
Your formatting the time output seem ok, just for better formats see Custom TimeSpan format strings.
Your code have three problem:
1. If Conditions
if (currentTime <= weedMinuteEvening)
{
//this condition is true from 00:00:00 to 16:21:01 so for dates less than 4:21:00
//you get incorrect output, and next condition execute just for dates greater than 16:21:00.
...
}
else if (currentTime >= weedMinuteMorning)
{
//This code execute only for dates greater than 16:21:00.
...
}
As Adam suggested you must remove .TimeOfDay from currentTime but this not enough.
You must handle dates grater than 16:21:00
So i hope this code work for you:
[Command("420")]
public async Task WeedMinute()
{
DateTime currentTime = DateTime.Now; //Current time
DateTime weedMinuteMorning = Convert.ToDateTime("4:21:00"); //4:20am
DateTime weedMinuteEvening = Convert.ToDateTime("16:21:00"); //4:20pm
//I removed These variables, Don't need to parse same DateTime again. change it as you wish
//string weedMinutePM = "16:21:00";
//string weedMinuteAM = "4:21:00";
if (currentTime <= weedMinuteMorning)
{
TimeSpan timeSpan = weedMinuteMorning.Subtract(currentTime);
await Context.Channel.SendMessageAsync("The next weed minute will happen in " + timeSpan.ToString("hh' hours 'mm' minutes.'"));
}
else if (currentTime <= weedMinuteEvening)
{
TimeSpan timeSpan = weedMinuteEvening.Subtract(currentTime);
await Context.Channel.SendMessageAsync("The next weed minute will happen in " + timeSpan.ToString("hh' hours 'mm' minutes.'"));
}
else
{
//To handle dates greater than 16:21:00, we must calculate hours
//remaining until 4:20 next day.
weedMinuteMorning = weedMinuteMorning.AddDays(1);
TimeSpan timeSpan = weedMinuteMorning.Subtract(currentTime);
await Context.Channel.SendMessageAsync("The next weed minute will happen in " + timeSpan.ToString("hh' hours 'mm' minutes.'"));
}
}
First of all you should now im new in Programming, and english is not my mother language, im from germany.
I`m trying to write a programm, which says me how many Days, Hours and Minutes have passed, concluding to the user input. For the User input i have the double variable (time) and the integer (day), in this example i typed in 14.40 (its like 2.40pm, in germany we write it 14.40) and 2 (for tuesday).
Now i want to programm to Write the following sentence:
"Since Monday 1 Day, 14 Hours and 40 minutes have passed!"
Insted of that he prints out "Since Monday 1 Day, 1440 Hours and 0 minutes have passed!"
To split the double i used Math.Truncate to get the full hours (14), and then i subtract that from the the user input (14.40), to get the Minutes (40).
I can't find a solution in the Internet for that Problem, i hope you guys can help me with that.
class Program
{
static void Main(string[] args)
{
int day;
double time;
int VDays;
double VHours;
double VMinutes;
Console.Write("Which day do we have? (1=Monday, 2=Tuesday, ...):\n");
day = Convert.ToInt32(Console.ReadLine());
Console.Write("Which time is it?\n");
time = Convert.ToDouble(Console.ReadLine());
VDays = day - 1;
VHours = Math.Truncate(time);
VMinutes = time - VHours;
Console.WriteLine("Since Monday" + VDays + " Day, " + VHours + " Hours and " + VMinutes + " minutes have passed!");
Console.ReadLine();
}
}
Having tested it I can confirm this is a locale issue as Klaus Gütter mentioned.
Since Convert.ToDouble uses your German locale settings and commas are the decimal separators in German, it ignores the dot and interprets 14.40 as 1440.
You can recreate the problem with:
time = Convert.ToDouble(Console.ReadLine(), CultureInfo.GetCultureInfo("de-DE").NumberFormat);.
You can specify the locale to be used to fix the problem, here with InvariantCulture:
time = Convert.ToDouble(Console.ReadLine(), CultureInfo.InvariantCulture);
You also need to multiply VMinutes by 100 for it to work, since substracting the integer value from the time will leave you with a number between 0 and 1 (i.e 14.40 - 14 = 0.40, 0.40 * 100 = 40 minutes have passed).
I want to know how to calculate the last date of this pay period?
I know that the pay is bi-weekly and the first period started on 01/09/2012.
so far here what i have done
DateTime d = new DateTime();
d = Convert.ToDateTime("01/09/2012");
while (d <= Convert.ToDateTime("01/06/2013")) {
PayPeriod.Items.Add(new ListItem(d.ToString("MM/dd/yyyy"), d.ToString("MM/dd/yyyy")));
d = d.Date.AddDays(14);
}
And this work perfect, but it work perfect because I have manually put the ending of the current pay period "01/06/2013".
My question is how can I automatically figure out the last date of the current pay period?
You can easily do this with the following logic:
DateTime startTime = new DateTime(2012,09,01);
DateTime now = DateTime.Now;
var diff = now.Subtract (startTime);
int daysToEndPeriod = diff.Days % 14;
if (daysToEndPeriod == 0)
Console.WriteLine("end of pay period");
else
Console.WriteLine("end of pay period is: " + DateTime.Now.AddDays(14-daysToEndPeriod).Date);
This works because you'll always get the Modulo operator returns how many days past the pay period you have left.
Question as title, this is not working, can't understand why:
// Get total steps, current step and duration in milliseconds
int current = stats[0]; int total = stats[1]; int duration = stats[2];
// Calculate the time span (of remaining time)
var remaining = TimeSpan.FromMilliseconds((total - current) * duration);
// Update the label
label.Text = string.Format("Tempo rimanente: {0}",
(new DateTime(remaining.Ticks)).ToString("hh:mm:ss"));
Try changing
(new DateTime(remaining.Ticks)).ToString("hh:mm:ss"));
To
remaining.Hours + ":" + remaining.Minutes + ":" + remaining.Seconds);
OR even:
// Update the label
label.Text = string.Format("Tempo rimanente: {0:00}:{1:00}:{2:00}",
remaining.Hours, remaining.Minutes, remaining.Seconds)
Why are you trying to convert a TimeSpan to a DateTime at all? "Remaining time" is a concept which is ideally suited to a TimeSpan, not a DateTime. You might want to convert it to the "estimated completion time" which would be a DateTime, but otherwise just use the TimeSpan.
Note that in .NET 4, TimeSpan gained custom format abilities, if you really need them - but I suspect the default format is likely to be okay for you, at least to start with.
