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

How to make datetime.now return date in UK format with c#

I want datetime.now to return the datetime object in UK format. It does so on my local computer but when I upload the code to the server it does it in US format

DateTime doesn't have any format associated with it. Formatting is just for presentation. You can do:
string formattedDate = DateTime.Now.ToString(CultureInfo.CreateSpecificCulture("en-GB"));
Or supply a specific/custom format like:
string formattedDate = DateTime.Now.ToString("dd/MM/yyyy HH:mm:ss",
CultureInfo.InvariantCulture);

I want datetime.now to return the datetime object in UK format.
There's no such concept, any more than an int is a value "in hex" or "in decimal". A DateTime is just a DateTime - you can specify the format when you convert it to a string. It's really important to understand the difference between an inherent value, and what it looks like after it's converted to text - very few types are aware of a custom, modifiable format to use when converting themselves - it's either provided externally (as for DateTime, numbers etc) or simply fixed.
Before you convert start hard-coding a UK format though, I would strongly advise you to consider exactly what you're doing:
Ideally, avoid the conversion in the first place. A lot of the time, string conversions are unnecessary and can be problematic.
Is the text going to be consumed by another machine? Use an ISO-8601 standard format.
Is the text going to be consumed by a person? Use their culture rather than some arbitrary one you decide on.
... Or display it in a dedicated control...

You can use the overload of the ToString method: ToString("dd/MM/yyyy"), or: ToString("yy/MMM/dd"), etc. etc.

Also sounds to me that you might want to configure your (UI-)Culture in the web.config? Then it will always be in the same format regardless of the culture of your US/Japanese/european server culture..

LogDate = DateTime.UtcNow.AddHours(1);

C# DateTime to be copied without format getting changed

I have a date and time which should be copied to DateTime object without changing its format.
Is there a way to resolve it?
Pls see the code below
string dateTime = "07/20/11 14:40:28";
DateTime copyDateTime = Convert.ToDateTime(dateTime);
string dateTime2 = copyDateTime.ToString();
Output:
{7/20/2011 2:40:28 PM}
If you notice the output, it got changed to PM. I want it as it is. How to get it?
EDIT:
I want dateTime2 to have the value exactly as it was for dateTime.

Format is not intrinsically associated with the DateTime. Format is simply a display property.
If you need to display it in your preferred format than simply call:
Console.WriteLine(copyDateTime.ToString("G"));
See MSDN for a complete list of standard format strings.

Before outputting, you need to convert the DateTime back into a string. By default, it simply calls "ToString" which uses the default DateTime format configured for the current user/locale.
Use ToString and specify a format to convert the datetime back into a String, then you can control the format.

Datetime formats and JSON data in C#

I'm having an issue with date/time formats in ASP.NET/C#. I have my SQL Server database set up with a PostDate field set to a type of "datetime". But it's saving the date in a strange format. I added a new row through a form and I got this as the date/time string:
2012-09-28 14:56:48.910
When it gets parsed by JSON.NET it gets even stranger. I get:
2012-09-28T14:56:48.91
The date and time are obviously correct, but how do I set things so that I can parse the date into a human-friendly way? There isn't really any code to post because the date is being added when the row is inserted. I'd like to format this as "Sept. 28, 2012 2:56 pm". How do I do that? Do I need to format the string before or after it's parsed as JSON?

That's not a "strange" format at all. The second form is ISO-8601; the first is ISO-8601 without the T. Considering the strange formats you can get in JSON, it looks like you've been let off pretty lightly!
Serialization formats aren't meant to be user-friendly, particularly - they're meant to be machine-to-machine formats.
I would hope that JSON.NET would give you a DateTime after parsing; it should only be giving you the ISO-8601 format after you've converted back to JSON.
If you've got a DateTime that you want to format for user consumption, there are all kinds of options with standard and custom format strings. Don't forget that you should respect the culture of the user, as far as possible - so make sure you're taking appropriate steps to either set the thread's current culture to be the user's one, or that you're passing the culture explicitly to DateTime.ToString etc.

You can try it in C#:
.ToString("MMM d yyyy, h:mm tt")

Retrieve format of date from date value

I am receiving some data into a variable of type object. In certain cases this data are date values. For that data, I would like to convert this to a string and return it in the same format as it was passed. In some cases, the object could be a datetime, in others a date only or time only values.
As soon as I convert the object to a date or a string, it is obviously given a time of midnight which in my scenario may be a valid time (so I cannot test to see if the time is midnight in which case I could deduce that it would have been a date only date value, nor can I use regex on it as there will always be a time element).
Intellisense shows me it correctly, ie in the format I am wishing to return the value.
Is there an easy way to achieve this (hopefully without using reflection)
Many thx
Simon

Your question is a little unclear but I think you're looking for something like this:
DateTime result;
if (DateTime.TryParse(value, out result))
{
// use result here
}
In the above code value is a string that represents the data coming in. The code will only enter the if block if the string is a valid DateTime. At which point you can do the processing you need on it.

Im not sure i understand the question but i would recommend you to take a look at this conversion example on MSDN, and see the Documentation of the DateTime Structur it contains a lot of Conversion/Formatting Methods i hope it helps.

There are many way to do formatting on the datetime and one of the simple way is fetch the data from the required table in the desired format. Like here you need to display the date and if you your format is dd/MM/yyyy then try this
select Convert(varchar(10),StartDate,103) as StartDateformat from table where filtername=#filtername
use this link to find other format Cast and Convert
From local variable to DateTime Conversion
DateTime todateformat = Convert.ToDateTime(txttodate.Text.Trim());
From DateTime to local variable Conversion in specific format
string startdate = todateformat.ToString("dd/MM/yyyy hh:mm:ss");
