In earlier vb.net 2008 I used the DateTime to read the date in dd/mm/yy format.
I use to change the culture info to UK format. So that the date will be selected from SQL server as in dd/mm/yy format.
But I know it's not good to play with CultureInfo. Even though I used like the following manner.
Any other better Ideas for me?
Sub Form_Load()
Thread.CurrentThread.CurrentCulture = New CultureInfo("en-GB", False)
End Sub
Any other better Ideas for me? Thanks for the Ideas.
Thanks & Regards.
From DateTime to string:
string s = DateTime.Today.ToString("dd/MM/yyyy");
From string to DateTime:
DateTime d;
bool success = DateTime.TryParseExact("26/05/2011", "dd/MM/yyyy", CultureInfo.InvariantCulture, DateTimeStyles.None, out d);
In C# you could get the date string in desired format like,
string date = DateTime.Now.ToString("dd/MM/yyyy");
If you want to get DateTime object from string value representing DateTime in specific culture, you can do
DateTime dt = new DateTime();
DateTime.TryParse("16/01/2011", System.Globalization.CultureInfo.CreateSpecificCulture("en-GB"),
System.Globalization.DateTimeStyles.None, out dt);
DateTime --> String
DateTime.Now.ToString( new CultureInfo("fr-FR", false) );
String --> DateTime:
The preferred method would probably be DateTime.Parse()
dateString = "16/02/2008 12:15:12";
try
{
dateValue = DateTime.Parse(dateString, new CultureInfo("en-GB", false));
Console.WriteLine("'{0}' converted to {1}.", dateString, dateValue);
}
catch (FormatException)
{
Console.WriteLine("Unable to convert '{0}'.", dateString);
}
This way you are not changing the Culture info of the current Context. This does assume you know what the format will be beforehand though.
You can format the date using the CultureInfo, without setting the culture for the whole thread, thanks to the IFormatProvider interface:
DateTime d = DateTime.Now;
CultureInfo c = new CultureInfo("en-GB", false);
string s = d.ToString(c.DateTimeFormat);
This has the added advantage that you don't have any hard-coded formats, and if the user changes the localisation settings on their machine, your application will reflect their preferences.
You can use DateTime.TryParse to parse the date...
string s = "01/01/2011";
DateTime date;
if (DateTime.TryParse(s, out date))
{
// Parsed correctly
}
else
{
// Invalid string!
}
And even use an IFormatProvider to help TryParse work out the format.
CultureInfo c = new CultureInfo("en-GB", false);
string s = "01/01/2011";
DateTime date;
if (DateTime.TryParse(s, c.DateTimeFormat, DateTimeStyles.None, out date))
{
// Parsed correctly
}
else
{
// Invalid string!
}

I want my date to be converted to UK date format.
so example if its 26/2/2016 then it should be converted to 26/02/2016.
if its a 2/13/2016 then it should be converted to 13/02/2016.
The end result should be UK format with preserving 0 in day and month.
Code
string cellvalue;
string oData = "2/13/2016";
if (DateTime.TryParse((string)oData, CultureInfo.CurrentUICulture, styles, out dt))
{
cellvalue = dt.ToString("dd/MM/yyyy");
Console.WriteLine(cellvalue + "go to hell");
}
else
{
cellvalue = oData.ToString();
Console.WriteLine(cellvalue + "go to bokaro");
}
Easyyy:
CultureInfo enGB = new CultureInfo("en-GB");
string oData = "2/13/2016";
DateTime dateValue;
// Parse date with no style flags.
dateString = "13/02/2016";
DateTime.TryParseExact(oData, "g", enGB, DateTimeStyles.None, out dateValue);
As far as I understand you want resulting date to be in default UK format i.e. dd/MM/yyyy no matter if input date string is in MM/dd/yyyy or dd/MM/yyyy, former being default format for US dates.
You were close in the code you have already tried. Additionally you need to one thing - if input is in US format, parse it as DateTime using US culture, and then simply transform to UK.
var UKCulture = new CultureInfo("en-GB");
var USCulture = new CultureInfo("en-US");
DateTime dt;
string cellvalue;
string oData = "13/2/2016";
// First try parsing to UK format
if (!DateTime.TryParse(oData, UKCulture, DateTimeStyles.None, out dt))
{
// If fails, then try US format
DateTime.TryParse(oData, USCulture, DateTimeStyles.None, out dt);
}
// Once you have DateTime instance, you can do anything. Parsing is over.
cellvalue = dt.ToString("dd/MM/yyyy");
Console.Write(cellvalue);
So now this gives final value as 13/02/2016 for both 2/13/2016 and 13/2/2016 inputs.
In my property below I m parsing string to datetime.
public virtual string StartTimeLocal
{
set { StartTime = DateTime.Parse(value).ToUTCDateTime(); }
}
Just checked in value I have 26/1/2014 02:17 PM
Can you please help me what wrong I m doing and how to correct it ?
DateTime.Parse parses standart date and time formats. Your string is not one of them.
You can use DateTime.TryParseExact or DateTime.ParseExact methods instead.
string s = "26/1/2014 02:17 PM";
DateTime dt;
if(DateTime.TryParseExact(s, "dd/M/yyyy hh:mm tt",
CultureInfo.GetCultureInfo("en-US"),
DateTimeStyles.None, out dt))
{
Console.WriteLine(dt);
}
else
{
//Your string is not a valid DateTime.
}
Your input is formatted using en-US culture settings, so you should either make sure your application runs on system with local culture set to en-US or specify culture explicitly:
public virtual string StartTimeLocal
{
set { StartTime = DateTime.Parse(value, CultureInfo.GetCultureInfo("en-US")).ToUTCDateTime(); }
}
Try the below:
CultureInfo provider = CultureInfo.InvariantCulture;
format = "dd/MM/yyyy hh:mm tt";
result = DateTime.ParseExact(dateString, format, provider);
when i am trying to connect c# code to mysql database there is a mistake in date datatype
try
{
CultureInfo CultureInfoDateCulture = new CultureInfo("ja-JP");
DateTime d = DateTime.ParseExact(accountend, "yyyy/MM/dd", CultureInfoDateCulture);
return true;
}
catch
{
return false;
}
when i have to collect date from the month calender i have used this validation for MYSQL and the datatype i have used is DATE datatpe
I have been getting the folllowing error
String was not recognised as a valid date time
please help me guys.... Thanks in advance
MYSQL Date Format is yyyy-MM-dd so you should use the same format while parsing it in the DateTime.ParseExact() method.
Try This:
DateTime d = DateTime.ParseExact(accountend, "yyyy-MM-dd",
CultureInfoDateCulture);
EDIT : From Your Comments your Date Format is M/d/yyyy
Try This:
DateTime d = DateTime.ParseExact(accountend, "M/d/yyyy",
CultureInfoDateCulture);
DateTime.ParseExact requires that the format string represent accurately the day, month and year of the string that need to be converted
So assuming that your date string is 4/11/2014 (day, month, year) you need
try
{
CultureInfo CultureInfoDateCulture = new CultureInfo("ja-JP");
DateTime d = DateTime.ParseExact(accountend, "d/M/yyyy", CultureInfoDateCulture);
return true;
}
catch
{
return false;
}
instead if the format is month, day, year, the format string is
DateTime d = DateTime.ParseExact(accountend, "M/d/yyyy", CultureInfoDateCulture);
By the way, your date is in the format expected by the InvariantCulture, so you could avoid the creation of the CultureInfo in this context, it is enough to use
DateTime d = DateTime.Parse(accountend, CultureInfo.InvariantCulture);
I'm parsing a DateTime value in an ASP.NET WebForms page and the date string keeps getting rejected by the DateTime.TryParseExact() method even though it clearly matches one of the supplied format strings.
It seems to fail on my development machine at home but work on the production server, so I am thinking of local date settings being involved, but this error occurs even when I supply an IFormatProvider (CultureInfo) object as a parameter
Here's the code:
DateTime startDate;
string[] formats = { "dd/MM/yyyy", "dd/M/yyyy", "d/M/yyyy", "d/MM/yyyy",
"dd/MM/yy", "dd/M/yy", "d/M/yy", "d/MM/yy"};
var errStart = row.FindControl("errStartDate"); //my date format error message
if (!DateTime.TryParseExact(txtStartDate.Text, formats, null, DateTimeStyles.None, out startDate))
{
errStart.Visible = true; //we get here even with a string like "20/08/2012"
return false;
}
else
{
errStart.Visible = false;
}
Note I'm giving a null FormatProvider in the above, but the same problem occurs when I provide a CultureInfo object as
(CultureInfo provider = new CultureInfo("en-US")) for this parameter.
What am I missing?
Try:
DateTime.TryParseExact(txtStartDate.Text, formats,
System.Globalization.CultureInfo.InvariantCulture,
System.Globalization.DateTimeStyles.None, out startDate)
Here you can check for couple of things.
Date formats you are using correctly. You can provide more than one format for DateTime.TryParseExact. Check the complete list of formats, available here.
CultureInfo.InvariantCulture which is more likely add problem. So instead of passing a NULL value or setting it to CultureInfo provider = new CultureInfo("en-US"), you may write it like.
.
if (!DateTime.TryParseExact(txtStartDate.Text, formats,
System.Globalization.CultureInfo.InvariantCulture,
System.Globalization.DateTimeStyles.None, out startDate))
{
//your condition fail code goes here
return false;
}
else
{
//success code
}
This is the Simple method, Use ParseExact
CultureInfo provider = CultureInfo.InvariantCulture;
DateTime result;
String dateString = "Sun 08 Jun 2013 8:30 AM -06:00";
String format = "ddd dd MMM yyyy h:mm tt zzz";
result = DateTime.ParseExact(dateString, format, provider);
This should work for you.
Try C# 7.0
var Dob= DateTime.TryParseExact(s: YourDateString,format: "yyyyMMdd",provider: null,style: 0,out var dt)
? dt : DateTime.Parse("1800-01-01");
string DemoLimit = "02/28/2018";
string pattern = "MM/dd/yyyy";
CultureInfo enUS = new CultureInfo("en-US");
DateTime.TryParseExact(DemoLimit, pattern, enUS,
DateTimeStyles.AdjustToUniversal, out datelimit);

I have a problem while converting a string whose value is dd.mm.yyyy to DateTime in c#
string OriginalDateFormat = "28.06.2009";
DateTime dt= Convert.ToDateTime(OriginalDateFormat);
Throwing an exception "String was not recognized as a valid DateTime."
But if it is in mm.dd.yyyy then it is running fine.
I googled and got lots of sites but all in vain
Any idea?
Thanks in advance.
Use DateTime.ParseExact and specify the exact format string:
DateTime dt = DateTime.ParseExact("28.06.2009", "dd'.'MM'.'yyyy",
CultureInfo.InvariantCulture);
If this is the value is from user input, you probably want to use DateTime.TryParseExact so you can handle failure gracefully:
DateTime dt;
if (DateTime.TryParseExact("28.06.2009", "dd'.'MM'.'yyyy",
CultureInfo.InvariantCulture,
DateTimeStyles.None, // Default formatting options
out dt))
{
Console.WriteLine("Successfully parsed {0}", dt);
}
else
{
Console.WriteLine("Did not recognise date");
}
I think its an issue with culture...The format you specified is (I think) GB and the default culture is US.
You will need to specify the culture also.
Instead try this:
IFormatProvider culture = new CultureInfo("en-US", true);//en-Us or en-GB not sure
DateTime dt = DateTime.Parse(p, culture, DateTimeStyles.AssumeLocal);
