I got a DateTime in a string format :
"05/30/2014 12:00:00"
I want to create a DateTime object from this string by doing this :
DateTime startDate = DateTime.Parse(startDate);
However, I've got an error which says that this method has some invalid argument :
Error 1 - The best overloaded method match for 'System.DateTime.Parse(string)' has some invalid arguments
When I'm reading the doc, a string argument is definitely a good argument. What's wrong with what I'm doing?
Use DateTime.ParseExact and pass the format you have in date string. The current culture might have date form in which day comes before month like dd/mm/yy.
You are passing the same variable to ParseExact method that you have declared for DateTime. Change the name of DateTime object.
DateTime dtStartDate = DateTime.ParseExact(startDate, "MM/dd/yyyy HH:mm:ss", CultureInfo.InvariantCulture);
You can read the article from Custom Date and Time Format Strings to get more understanding for declaring the format for parsing the date string.
DateTime startDate = DateTime.ParseExact(strDate, "G", CultureInfo.InvariantCulture);
You can find more info on this here.
It looks like you are passing in your variable to parse before you have initialised it.
So you could have:
DateTime startDate = DateTime.Parse("05/30/2014 12:00:00");
Console.WriteLine(startDate);
Or, you could have:
String dateToParse = "05/30/2014 12:00:00";
DateTime startDate = DateTime.Parse(dateToParse);
Console.WriteLine(startDate);
Store your date inside a string variable and then use following:
DateTime.Parse(STRINGVARIABLE);
//Which means following
//DateTime.Parse("05/30/2014 12:00:00");
In your code, you are trying apply the format to the variable of type DateTime. Or if you want to apply the format directly to DateTime variable then you can simply write following:
DateTime.Parse("05/30/2014 12:00:00").ToString("dd MMM yyyy");

I have a property (string) named as cdate in this format
25/01/2019 12:41:50 AM
I want my output to look like this 01/25/2019 12:41:50 AM
My code is throwing an invalid cast exception error.
I am a rookie in C#
Already I have tried this but it's not working
cdate.ToString("MM/dd/yyyy hh:mm:ss")
As you've stated in a comment to another answer cdate is of type string.
You'll need to parse the string to a DateTime and then call ToString() to format the date in the appropriate format
var cdate = "25/01/2019 12:41:50 AM";
var dt = DateTime.ParseExact(cdate, "dd/MM/yyyy hh:mm:ss tt", CultureInfo.InvariantCulture);
cdate = dt.ToString("MM/dd/yyyy hh:mm:ss tt");
This uses CultureInfo.InvariantCulture otherwise / and : get replaced with whatever the current culture's date and time separators are.
What is the type of property cdate? I am assuming that it is of type DateTime and I am also assuming that you are trying to do something like this:
cdate = cdate.ToString("MM/dd/yyyy hh:mm:ss")
In this case you will get a cast exception exception because you are trying to assign a string value to a DateTime variable (DateTime.ToString returns a string).
You should probably assign it to a new string variable instead of trying to assign it to cdate.
Edit:
Since the type of cdate is string then you should cast it to a DateTime object use ToString method to convert it to the required format.
cdate = DateTime
.ParseExact(cdate, "dd/MM/yyyy hh:mm:ss tt", CultureInfo.InvariantCulture)
.ToString("MM/dd/yyyy hh:mm:ss tt", CultureInfo.InvariantCulture);
Try this one with specifying culture format(as you want en-US format). Exactly cdate is a DateTime instance here.
cdate.ToString("G", CultureInfo.CreateSpecificCulture("en-us"));
if you are looking for parsing DateTime from a string:
DateTime dt = DateTime.Parse(cdate, CultureInfo.CreateSpecificCulture("en-us"));

I am trying to convert Time string to DateTime but can't.
Example: Time: 12:05:45.458 with milliseconds need to convert to time.
Any solution?
DateTime.ParseExact should solve this
DateTime result = DateTime.ParseExact("12:05:45.458", "HH:mm:ss.fff", CultureInfo.InvariantCulture);
The DateTime.ParseExtract will parse the given time and convert to DateTime object with date as current date.
var dateTime = DateTime.ParseExact("12:05:45.458", "HH:mm:ss.fff", System.Globalization.CultureInfo.InvariantCulture);
Console.WriteLine(dateTime);
You are looking for a Timespan.Parse() here. Since you do not have any date component, it is not possible to unambiguously convert to a DateTime instance.
Simple solution:
string time = "12:05:45.458";
DateTime dateTime = DateTime.ParseExact(time, "HH:mm:ss.fff",
CultureInfo.InvariantCulture);

I know this has been asked a lot of times, but none seems to relate to my problem (all answers specifies another datetime format than the one which is giving me issues):
Convert string(dd/MM/yyyy hh:mm) to datetime format
Converting a String to DateTime
Convert dd/MM/yyyy hh:mm:ss.fff from String to DateTime in C#
Specific example:
Input is a string: 24/10/2016 10:20
I call DateTime.TryParse(input, out output)
The output is a DateTime: {1/1/0001 12:00:00 AM}
Why? This is a perfectly valid input format from what I know...
Things I tried / restrictions:
Change the input to have a second: 24/10/2016 10:20:00, it works
Use TryParseExact, specifying this format, it works
However, I cannot use both these solutions as the input is user defined, I cannot force the user to stick to a specific input, and want to accept any reasonably formatted date times. The format I specified in the question seems reasonable (it's the default format outputted by Excel).
I can assume the culture is en-US
Any help would be appreciated.
Update:
The top answer to the first question throws an exception... I don't know why that's even up-voted.
Update 2:
Since there are a lot of close requests, here's some minimal working code (duplicated from the answer by Mohit Shrivastava):
string dtstr = "24/10/2016 10:20";
DateTime outdt;
DateTime.TryParse(dtstr, out outdt);
Console.WriteLine(outdt);
Console.ReadLine();
Your output is 1/1/0001 12:00:00 AM which is the min value of the DateeTime object, which means that the conversion failed(as per this documentation). The string input is parsed using formatting information in the current DateTimeFormatInfo object, which is supplied implicitly by the current thread culture. So the problem is the format of the date-string that you are passing.
Try using TryParseExact method in a smarter way since you know the format of the string input, like the following:
string dateString ="24/10/2016 10:20";
string formatString="dd/MM/yyyy HH:mm";
DateTime dateValue;
CultureInfo enUS = new CultureInfo("en-US"); // is up to you
if (DateTime.TryParseExact(dateString, formatString , enUS,
DateTimeStyles.None, out dateValue))
The same code gives the correct output on my machine.
string dtstr = "24/10/2016 10:20";
DateTime outdt;
DateTime.TryParse(dtstr, out outdt);
Console.WriteLine(outdt);
Console.ReadLine();

By default DateTime type in C# gave time in AM/PM format, but I would like to return 24 hrs time format and same time I want to return this DateTime type instead of string like below,
DateTime localTime = DateTime.Now;
string timeString24Hour = localTime.ToString("dd-MM-yyyy HH:mm:ss", CultureInfo.InvariantCulture) ;
instead of "string timeString24Hour" I want "DateTime timeString24Hour"
How to achieve this???
DateTime localTime = DateTime.Now;
That is a DateTime type in 24-hour format. A DateTime is a number representing all of the milliseconds since January 1, 1970. From it, you can convert to any part of time, or any string of time. If you want to use a DateTime, though - there is no inherent formatting to it until you need one by using
DateTime.Hours/DateTime.DayOfWeek/DateTime.Subtract(antoherDateTime).TotalSeconds
if/when you need time in a 24- hour format. Just use:
DateTime.ToString("HH:mm")
from here: How to format DateTime to 24 hours time?
By default DateTime is dispalyed in AM/PM in your culture.
Because the developement environment always uses the current culture to display DateTime
But that's only how it is being displayed. The value within DateTime is the same - culture independent.
By th way "mm/dd/yyyy HH:mm:ss" is invalid becasue mm are minutes and MM is for month
I presume you want something like String.Format :
DateTime localTime = DateTime.Now;
string timeString24Hour = String.Format("{0:dd-MM-yyyy HH:mm:ss.fff}", localTime);
Or shorter:
string timeString24Hour = String.Format("{0:dd-MM-yyyy HH:mm:ss.fff}", DateTime.Now);

I have a input variable with DateTime datatype in "03-Jan-2010" format I want to convert that in to a String type of dd/MM/yyyy format.How can this be done using C#.
Just use DateTime.ToString(string) method like;
datetime.ToString(#"dd\/MM\/yyyy");
Remember, "/" format specifier has a special meaning in custom date and time formatting as replace me current culture's or specified culture date separator. If your CurrentCulture's DateSeparator is already /, you can use it without escaping like;
datetime.ToString("dd/MM/yyyy");
or you can provide IFormatProvider which has / as a DateSeparator as a second parameter to your .ToString() method (ex: InvariantCulture ) like;
datetime.ToString("dd/MM/yyyy", CultureInfo.InvariantCulture);
string ddd= DateTime.Now.ToString("dd-MM-yyyy");
Visit: http://forums.asp.net/t/1820419.aspx?How+to+convert+dd+mm+yyyy+format+date+into+yyyy+dd+mm+in+C+
Please try following demo you will get what you want
string myDate = "03-Jan-2010";
DateTime dt = DateTime.Now;
DateTime.TryParseExact(myDate, "dd-MMM-yyyy", null, System.Globalization.DateTimeStyles.None, out dt);
string formattedDate = dt.ToString("dd/MM/yyyy");
Console.Write("Formatted Date : {0}", formattedDate);
Console.ReadKey();
Hope it works for you...
