DateTime.TryParse() not working with formatted date dd/MM/yyyy

This code returns (min time 1/1/0001 12:00:00 AM) not Date.Time.Now . Try Parse works for MM/dd/yyyy but not dd/MM/yyyy . Any suggestions
Here is code
DateTime start, end;
DateTime.TryParse(EPSDate12.Text, out start);
string TNow = DateTime.Now.ToString("dd/MM/yyyy HH:mm:ss"); // Works
// string TNow = DateTime.Now.ToString();// works but gives MM/dd/yyyy as expected
DateTime.TryParse(TNow, out end); // No. gives min time (1/1/0001 12:00:00 AM)

Use TryParseExact and supply the format string.
Also examine the return value from TryParseExact to know if it failed or not (it returns a bool)
I see "EPSDate12.Text" which i suspect may be a TextBox: If you're doing this in a UI, make life easy and use a DateTimePicker - you can set the format, the user can type into them just like a textbox, but they don't accept invalid inputs, and all you have to do is get the .Value property which gives you a DateTime
As to why your attempts to parse the string you made don't work, I think it most likely that the date format Parse is using (which is based on the culture settings of the executing thread) is not the same format as the string you prepared using your forced format. Either make sure your forced format is matched to the current culture, or use a culture that matches your forced format, or use [Try]ParseExact to force the format for parsing like you did when creating the string
See https://learn.microsoft.com/en-us/dotnet/api/system.datetime.parse?view=net-5.0#Culture for more info

The datetime value is internally the same. But, ToString() return value, depends on
the local machine culture setup.
Reference article
The default DateTime.ToString() method returns the string
representation of a date and time value using the current culture's
short date and long time pattern. The following example uses the
default DateTime.ToString() method.
For en-US culture(MM/dd/yyyy hh:mm:ss) , it will be in
7/28/2021 11:37:40 AM
If you want to see in en-GB(dd/MM/yyyy hh:mm:ss), you can apply conversion as given below:
var culture = new CultureInfo("en-GB");
MessageBox.Show($"{DateTime.Now.ToString(culture)}");
28/07/2021 11:45:09 AM
you can also specify exact custom format, in which you want to display.
MessageBox.Show($"{DateTime.Now.ToString("dd/MM/yyyy HH:mm:ss tt")}");

Thanks for suggestions . Yes DateTime.TryParse is not working and it could be format issue
This line of code.
string TNow = DateTime.Now.ToString("dd/MM/yyyy HH:mm:ss");
generates
29/07/2021 14:49:03
which looks OK but fails TryParse

c# parse date time with timezone

How can we parse date time with time zone.
<TIMESTAMP_UTC>20180523160000</TIMESTAMP_UTC>
<TIMEZONE>UTC+8</TIMEZONE>
this should convert as in 2018-05-24 00:00:00.
I tried couple of things but could not succeed.
I tried the below command but it throws an error.
DateTime.ParseExact("20180523160000+08:00", "yyyyMMddHHmmssZhhmm", System.Globalization.CultureInfo.InvariantCulture)
Do you know how we can parse this with DateTime Parse methods.

You need to use DateTimeOffset.ParseExact
var date = DateTimeOffset.ParseExact("20180523160000+08:00", "yyyyMMddHHmmsszzz", CultureInfo.InvariantCulture);

Try using DateTimeOffset.Parse() instead of DateTime.Parse() as DateTimeOffset stores timezone info.
You can refer to the following MSDN link for more details:
https://msdn.microsoft.com/en-us/library/bb351654(v=vs.110).aspx

You could invert the sign of your timezone and then parse it with
var dateTime = DateTime.ParseExact(
"20180523160000UTC-8",
"yyyyMMddHHmmssUTCz",
CultureInfo.InvariantCulture);
But if this is a good approach is probably questionable.

DateTime.Parse doesn't use patterns in current CultureInfo(Silverlight)?

I've got following problem.
I set CurrentCulture and CurrentUICulture and use following patterns in them:
ShortDatePattern is dd-MM-yyyy
LongTimePattern is HH.mm.ss.
When I convert dates to string I get 15-01-2008 00.00.00. But when i call DateTime.Parse("15-01-2008 00.00.00") it throws a FormatException. If i set ShortDatePattern to dd-MM-yyyy HH.mm.ss exception is still thrown. Is there any way to force DateTime.Parse to use pattern for time by setting CurrentCulture accordingly.
I know that using Parse overloads or ParseExact might help, but the whole point was to use formatting without refactoring loads of code that is already written and uses DateTime.Parse and ToString all over the place
Additional info: A also tried putting - and . in ' - it was no use. CurrentCulture is based on Swedish.

if you want to format a DateTIme using String.Format() Method you could do something like this below. String.Format DateTime C#
var dt = "15-01-2008 00.00.00";
var dateFrmt = String.Format("{0:dd/MM/yyyy HH:mm:ss}", dt);
Output = "15-01-2008 00.00.00"
if you want to strip the HH:mm:ss out of the DateTime variable for short date you could do the following here is an example will yield ShortDate
DateTime dt = DateTime.Now;
var dateFrmt = String.Format("{0:M/d/yyyy}", dt);
Output = "1/9/2013"
DateTime.ParseExact Method if you choose to go that route

Convert DateTime

This works:
testDateTime = DateTime.ParseExact("16/10/2010", "dd/MM/yyyy", null);
This does NOT:
string somedate = "16/10/2010";
testDateTime = DateTime.ParseExact(somedate, "dd/MM/yyyy", null);
why??

Both code snippets are absolutely equivalent and should work/not work the same. I suspect that the value of the somedate variable is not what you think it is inside your application. Try debugging.

Both of your examples are equivalent, and should work if your current culture is en-US, but not necessarily in all other cultures.
For example, the following will throw a FormatException because the de-DE culture uses period as a separator (16.10.2010):
System.Threading.Thread.CurrentThread.CurrentCulture =
CultureInfo.CreateSpecificCulture("de-DE");
DateTime testDateTime = DateTime.ParseExact("16/10/2010", "dd/MM/yyyy", null);
In general it's good practice (FxCop will warn about it) to always specify the IFormatProvider parameter when it's available: usually either CultureInfo.CurrentCulture if you're parsing input from the current user; or CultureInfo.InvariantCulture if you're parsing input from an external source.
// For input from the current user (16.10.2010 in Germany)
testDateTime = DateTime.ParseExact("16/10/2010", "dd/MM/yyyy", CultureInfo.CurrentCulture);
// For input from an external source in a defined culture-invariant format
testDateTime = DateTime.ParseExact("16/10/2010", "dd/MM/yyyy", CultureInfo.InvariantCulture);

It worked fine when I tried it... Just copied and pasted it.
Insert a breakpoint, put your pointer over the variable and check the month, day and year member. If they are not rights, show us what you see.
If you are using a print or msgbox to show the value of the variable, maybe you are not suplying a mask/format for the output.

You are trying to change the DateTime format right? You can not do that with a DateTime object. You can change the format only when you display the DateTime object using String.Format: String.Format("{0:d/M/yyyy HH:mm:ss}", dt). (for example or other methods)

Both the things worked for me when I tried. What is the error you are getting?
The ParseExact() uses the second parameter to parse your input string and not to return the value in that format.
EDIT: from Joe's comment below - The output you get will be in "MM/dd/yyyy" format" - the output will be a DateTime type that doesn't have any intrinsic format.

for some reason it would not work for me UNTIL i added this: CultureInfo.InvariantCulture
DateTime.ParseExact(sValue, "dd/MM/yyyy", CultureInfo.InvariantCulture);

How to convert data into DateTime object

How do I convert a date string, in the general form of "ccyymmdd" in to a DateTime object in C#?
For example, how would I convert "20100715" in to a DateTime object.
Please - No RTFM links to Microsoft Tech Docs.
Many Thanks...

using System.Globalization;
DateTime.ParseExact("20100715", "yyyyMMdd", CultureInfo.InvariantCulture);

var dt = DateTime.Parse("your date string").ToString("yymmdd");
I don't think cc is a valid date formatting option?
As Richard points out, you can also use DateTime.ParseExact which allows you to use culture information for the parsing, or you can use DateTime.TryParseExact which is the same as DateTime.ParseExact, but if there is an exception then a null date is returned rather then an exception being raised.
EDIT:
The question has been updated so that a DateTime is specifically returned. In that case you can omit the .ToString() part of my answer. Calling DateTime.Parse() will return a DateTime object. When getting the date value via ToString(), simply pass the required formatting string to get the date in the desired format.
Cheers.
Jas.

Take a look at this and this
DateTime.Parse();
DateTime.ParseExact();
And worth a mention
DateTime.TryParse();

If your date string is already sanitized (Borrowed from Mike's answer):
DateTime dt = DateTime.ParseExact("20100715", "yyyyMMdd", CultureInfo.InvariantCulture);
Otherwise:
DateTime dt;
if (!DateTime.TryParseExact("20100715", "yyyyMMdd", CultureInfo.InvariantCulture, DateTimeStyles.None, out dt))
{
// Handle bad date
}

System.DateTime.Parse(yourDateString)
You might have to manipulate your string to a format that the method can handle first.
See http://msdn.microsoft.com/en-us/library/1k1skd40.aspx
for more info

I'm not sure what the "cc" part is, but there are a few options.
DateTime.Parse(string) may be able to convert the string, but if the string is in a non-standard format you may have to do some pre-conversion first.
