I have a textfield that has a date with the format "12/23/2010".Is there away for me to get the number 23 using watin ie get number from textfield;i'm gonna use it like this.
1.Get datetime 12/23/2010 and get number '23'
2.substract 2 from 23 and store it somewhere[ie: 23 - 2 = 21]
3.Insert the new datetime number [ie:12/21/2010 ]
string myDate = browser.TextField(Find.ByName("myTextField")).Value;
DateTime time = = new DateTime();
time2 = time - 2;
browser.TextField(Find.ByName("myTextField")).TypeText(time2);
Is this possible?or should i be looking to another way.Ask the user to insert the data instead.
You should use DateTime.Parse, DateTime.TryParse, DateTime.ParseExact or DateTime.TryParseExact to parse from text to a DateTime.
If a failure to parse indicates a failure in the code somewhere (which is probably the case here, given that it's a test) I suspect DateTime.ParseExact is the most appropriate approach, providing the expected format, culture etc.
if what you want is to subtract 2 days from a date I would do it like this:
DateTime dt = DateTime.Parse(myDate)-TimeSpan.FromDays(2);
//its steps 1,2 & 3 in one easy to read line :)
This is of course if you are sure the string you have IS a valid date. If it might not be, then you should do what the Skeet recommends, which is using first a try parse, checking if the return value is true, and if it is, then do the rest, and if it is not, send an error message.
consider writing
DateTime dt = Convert.ToDateTime(myDate);
DateTime dtNew = new DateTime(dt.Year, dt.Month, dt.Day - 2);
browser.TextField(Find.ByName("myTextField")).TypeText(dtNew.ToShortDateString());
Try getting the value of the date as string
Convert it to datetime and use AddDays we can use negative or positive value
And insert it into textbox
string myDate = this.Elements.textfield.Value;
DateTime dt = Convert.ToDateTime(myDate);
DateTime dtNew = dt.AddDays(-3);
this.Elements.ChangeDateActive.TypeText(dtNew.ToShortDateString());
That's it thanks

when i run the below code,
string dt = "2017-07-09T17:50:21.000-0500";
DateTime date = Convert.ToDateTime(dt);
it gives me output as
7/10/2017 4:20:21 AM
where as i want my output to be
2017-07-09 17:50
update
the code #alexander-petrov gave worked
string dt = "2017-07-09T17:50:21.000-0500";
string date = DateTimeOffset.Parse(dt).DateTime.ToString("yyyy-MM-dd HH:mm");
gives output
2017-07-09 17:50
but on inserting the same to database it is adding +5 hrs to the time and inserting as
2017-07-09 22:50
This is a Round-Trip format of a DateTime specified with a DateTimeKind.Local kind.
You need to decide if your program needs to be aware of time zones or not.
You could try parsing it while supplying the System.Globalization.DateTimeStyles.RoundtripKind or System.Globalization.DateTimeStyles.AdjustToUniversal parameter to the Parse method.
If you want take offset into account then use DateTimeOffset type.
string dt = "2017-07-09T17:50:21.000-0500";
DateTimeOffset date = DateTimeOffset.Parse(dt);
// format on my machine
// 09.07.2017 17:50:21 - 05:00
Console.WriteLine(date);
// without offset
// 09.07.2017 17:50:21
Console.WriteLine(date.DateTime);
I couldn't get your date to work, as I think there is a colon missing in the last part. Adding that colon back allows me to convert the XSD date time into a SQL DATETIME using this script:
DECLARE #stringDate VARCHAR(30);
SELECT #stringDate = '2017-07-09T17:50:21.000-05:00';
DECLARE #xmlDate XML;
SELECT #xmlDate = CAST('' AS XML);
SELECT #xmlDate.value('xs:dateTime(sql:variable("#stringDate"))', 'datetime');
Results:
2017-07-09 22:50:21.000
Try:
string date = "2017-07-09T17:50:21.000-0500";
DateTime d = DateTime.ParseExact(date, "yyyy'-'MM'-'dd'T'HH':'mm':'ss'.'fffzzzz", null);
I have one field in database in this format: 2013-06-18 17:00:00.000
and second field Duration in this format: 3000 (this represents seconds, so it is 50 minutes)
I need to subtract those two fields and to set in another field result which will be: 2013-06-18 16:10:00.000
One addition is that they both can be retrieved from database in string format only. So they are both strings.
Thanks
First you need to Parse the datetime. Then subtract using AddSeconds:
var date = DateTime.Parse("2013-06-18 17:00:00.000");
var newDate = date.AddSeconds(int.Parse("-3000"));
You can use newDate.ToString() to get the date as a string.
You can find the documentation for DateTime here.
Update: Changed seconds to a string value. Which uses Parse to convert to an integer.
You can subtract to the datetime object. (if is a DateTime Type) if not, you should parse.
To handle errors, I would recommend to use DateTime.tryParse(value, out dateTime);
DateTime parsedDateFromBD;
if(DateTime.tryParse("2013-06-18 17:00:00.000", out parsedDateFromBD)
{
// do Stuff
}
else
{
// do something else
}
if you get it as a datetime from the db you can simply:
var calcDate1 = dateFromBD.addSeconds(3000); //to Add
var calcDate2 = dateFromBD.addSeconds(-3000); //to subtract
Cheers

In addition to the other answers here is how to parse the newDate to string that mach the required output
string date = "2013-06-18 17:00:00.000";
string duration = "-3000";
int durationSeconds = int.Parse(duration);
var newDate = DateTime.Parse(date).AddSeconds(durationSeconds).ToString("yyyy-MM-dd HH:mm:ss.fff");
The output is
//2013-06-18 16:10:00.000
Here you can find more about DateTime.ToString()
I have console application that accepts date as parameter. However, the date is passed as a string in this format:
string dt = DateTime.Now.ToString("yyyyMMdd");
Once the date is entered I need to programmatically get day - 1 from the entered date. Since this is a string, I cannot do any calculation.
For example, user enters:
20141023
I need to subtract a day from the date to get:
20141022
I did a quick fix to solve my immediate need, however, this is not the right way to do it and it has a bug:
int yt = Int32.Parse(dt) - 1;
And then I turn around and convert it yt.ToString()
The above solution will not work if it's the 1st of the month.
Is there a way I can programmatically get yesterday's date in the format (yyyyMMdd) without changing the format and possibly not using the TimeSpan?
Why don't parse the input into a DateTime object? Then you can use the DateTime.AddDays(-1)
For example:
var inputDate = DateTime.ParseExact("20141022", "yyyyMMdd", CultureInfo.InvariantCulture); // change "20141022" into the inputted value
var yesterday = inputDate.AddDays(-1);
var yesterdayString = yesterday.ToString("yyyyMMdd"); // this will be yesterdays date, in the string format
Try this...
DateTime data = DateTime.ParseExact("20141023", "yyyyMMdd", CultureInfo.InvariantCulture);
Console.WriteLine("{0} - {1}", data, data.AddDays(-1).ToString("yyyyMMdd"));
Would this work for you ?
string newDateTimeStr = (DateTime.Today.AddDays(-1)).ToString("yyyyMMdd");
EDIT:
for the date entered by the user:
string txtInputDate = Console.ReadLine();
DateTime dateTime = new DateTime(txtInputDate).ToLocalTime();
string newDateTimeStr = (dateTime.AddDays(-1)).ToString("yyyyMMdd");
Is there any way I don't have to specify the number of digits in day/month/year?
For e.g 1/2/1991
I want a method which satisfies both 1/2/1991,11/3/1990,12/12/1991
I don't know how many digits will be there in either month, year, or days.
My code is
string copy = splittedData[0] + splittedData[1] + splittedData[2];//date+month+year
DateTime datetime = DateTime.ParseExact(copy, "ddMMyyyy", CultureInfo.InvariantCulture);
DateTime dateAndTime = datetime;
The problem is the number of digits in splitted data array are not known to me and thus the above format "ddMMyyyy" give me exception on some cases.
Since you already have the day month and year then just create a date with the three of them like so;
DateTime date = new DateTime(year, month, day);
No parsing is necessary. You already have all the fields you want to create the date, and you dont need to put it into a special format to create a date.
If you are not sure the if the input is valid, then wrap the creation in a try/catch block to catch an ArgumentOutOfRangeException should it should occur.
Since you updated your question with the code you have, you can concatenate date components with a separator like:
string copy = splittedData[0] + "/" + splittedData[1] + "/" + splittedData[2];
Later you can do:
DateTime dt = DateTime.ParseExact(copy, "d/M/yyyy", CultureInfo.InvariantCulture);
I used the format "d/M/yyyy" with single d and M which would account for both single/double digit day/month.
So it will work for dates like:
01/01/2013
1/01/2013
22/09/2013
02/9/2013
DateTime.ParseExact is specifically intended to not allow what you are asking for. DateTime.Parse will allow it, though.
You say you have the 3 parts as separate strings -- if you insert the /'s and parse, it should succeed (InvariantCulture expects the order month-day-year):
string datetimeString = string.Join("/", new[] {month, day, year});
DateTime datetime = DateTime.Parse(datetimeString, CultureInfo.InvariantCulture);
Or you could convert them to integers and construct a DateTime directly:
DateTime datetime = new DateTime(Convert.ToInt32(year), Convert.ToInt32(month), Convert.ToInt32(day));
What #n00b said. You've already got the individual components of the date: why are you globbing them back together just so you can call DateTime parsing routines? Just do something like this:
private static DateTime StringToDateTime( string year , string month , string day )
{
int yyyy = int.Parse(year) ;
int mm = int.Parse(month) ;
int dd = int.Parse(day) ;
DateTime dt = new DateTime(yyyy,mm,dd) ;
return dt ;
}
As an added bonus, The above code will probably run faster than DateTime.Parse() or DateTime.ParseExact().
I want to retrieve yesterday's date in my ASP.NET web application using C#.
I've tried searching for a solution but have not had much success. The code I'm using just outputs today's date:
string yr = DateTime.Today.Year.ToString();
string mn = DateTime.Today.Month.ToString();
string dt = DateTime.Today.Day.ToString();
date = string.Format("{0}-{1}-{2}", yr, mn, dt);
How can I get yesterday's date?
Use DateTime.AddDays() method with value of -1
var yesterday = DateTime.Today.AddDays(-1);
That will give you : {6/28/2012 12:00:00 AM}
You can also use
DateTime.Now.AddDays(-1)
That will give you previous date with the current time e.g. {6/28/2012 10:30:32 AM}
The code you posted is wrong.
You shouldn't make multiple calls to DateTime.Today. If you happen to run that code just as the date changes you could get completely wrong results. For example if you ran it on December 31st 2011 you might get "2011-1-1".
Use a single call to DateTime.Today then use ToString with an appropriate format string to format the date as you desire.
string result = DateTime.Today.AddDays(-1).ToString("yyyy-MM-dd");
You don't need to call DateTime.Today multiple times, just use it single time and format the date object in your desire format.. like that
string result = DateTime.Now.Date.AddDays(-1).ToString("yyyy-MM-dd");
OR
string result = DateTime.Today.AddDays(-1).ToString("yyyy-MM-dd");
You will get yesterday date by this following code snippet.
DateTime dtYesterday = DateTime.Now.Date.AddDays(-1);
var yesterday = DateTime.Now.AddDays(-1);
Something like this should work
var yesterday = DateTime.Now.Date.AddDays(-1);
DateTime.Now gives you the current date and time.
If your looking to remove the the time element then adding .Date constrains it to the date only ie time is 00:00:00.
Finally .AddDays(-1) removes 1 day to give you yesterday.
string result = DateTime.Now.Date.AddDays(-1).ToString("yyyy-MM-dd");
DateTime dateTime = DateTime.Now ;
string today = dateTime.DayOfWeek.ToString();
string yesterday = dateTime.AddDays(-1).DayOfWeek.ToString(); //Fetch day i.e. Mon, Tues
string result = dateTime.AddDays(-1).ToString("yyyy-MM-dd");
The above snippet will work. It is also advisable to make single instance of DateTime.Now;
DateTime.Today as it implies is todays date and you need to get the Date a day before so you subtract one day using AddDays(-1);
There are sufficient options available in DateTime to get the formatting like ToShortDateString depending on your culture and you have no need to concatenate them individually.
Also you can have a desirable format in the .ToString() version of the DateTime instance
