How to convert DateTime object to dd/mm/yyyy in C#?

One thing to note in addition to the other answers - / is a format character itself, representing the local date separator. If you want to make absolutely sure it uses an actual slash, either use the invariant culture (which uses a slash):
string s = dateTime.ToString("dd/MM/yyyy", CultureInfo.InvariantCulture);
or escape the slashes:
string s = dateTime.ToString("dd'/'MM'/'yyyy");

Are you talking about converting to a string for printing or something?
String s = DateTime.ToString("dd/MM/yyyy");
And to be complete, here is more information about DateTime.ToString and DateTime formatting in general.

DateTime d = DateTime.Now;
string s = d.ToString("dd/MM/yyyy");
Console.WriteLine(s);

I can't figure a way to parse a Datetime object that is "10/24/2022 4:01:35 PM" to "24/10/2022 16:01:35".
Can't find an answer for this exact format.
Thanks in advance!
I guess you don't need to parse that string to DateTime since you have it already in Process.StartTime and you're looking at it in the debugger. Then use it directly. If you really have it as string you simply need to use DateTime.Parse with InvariantCulture:
DateTime dt = DateTime.Parse("10/24/2022 4:01:35 PM", System.Globalization.CultureInfo.InvariantCulture);
and for the output:
Console.Write(dt.ToString("dd'/'MM'/'yyyy HH:mm:ss"));

DateTime.ParseExact, Ignore the timezone

I have been searching to convert string to datetime with ignoring the offset.
I have a string with local date time as 2017-02-13T12:11:03.303 +01:00 i want to ignore the offset part and string should be converted to 2017-02-13 12:11:03.303 as datetime format. I searched google but could not find one.

Not a duplicate of DateTime.ParseExact, Ignore the timezone as while searching didn't know its realted to DateTimeOffset.Searched using layman terms and no proper result found.
Use the DateTimeOffset.Parse method:
string s = "2017-02-13T12:11:03.303 +01:00";
DateTime dt = DateTimeOffset.Parse(s, null).DateTime;

Converting a string to a DateTime with more than 7 decimals of milliseconds

I am trying to parse "31.01.2017 07:56:29.470000000"date time string into datetime format.
Code used:
DateTime requiredDate;
string date = "31.01.2017 07:56:29.470000000";
DateTime.TryParseExact(date,
"dd.MM.yyyy hh:mm:ss.fffffff",
CultureInfo.InvariantCulture,
DateTimeStyles.None,
out requiredDate);
NOTE: date string is exact "31.01.2017 07:56:29.470000000", however if I use "31.01.2017 07:56:29.4700000" then it is working fine.
Please parse "31.01.2017 07:56:29.470000000".
The problem lies in the maximum allowed number of fs in your parse string: The maximum value is fffffff (7 fractions). Your string contains 9 of them.
You can find this limitation in the documentation. It mentions all possible values between f and fffffff, but not further.
The problem is in the number of f which as a maximum of 7. You are using the Round-trip date/time pattern that complies with ISO 8601. Please see the documentation.
The "O" or "o" standard format specifier corresponds to the "yyyy'-'MM'-'dd'T'HH':'mm':'ss'.'fffffffK" custom format string for DateTime values and to the "yyyy'-'MM'-'dd'T'HH':'mm':'ss'.'fffffffzzz" custom format string for DateTimeOffset values.
As you can see, there are only 7 digits of f in the format indicated by the documentation.
To solve your problem you should remove the last 2 digit from your input.

i wanted to convert 26/Jun/2016 at 13:14 from a string to datetime data type
for saving to sql
string DtTime = ds.Tables["VOUCHER"].Rows[0]["BASICDATETIMEOFINVOICE"].ToString();
how to split as a string
You need to escape the / and the at in the format string, then you can use ParseExact:
DateTime.ParseExact("26/Jun/2016 at 13:14", "dd/MMM/yyyy 'at' HH:mm", CultureInfo.InvariantCulture);
https://learn.microsoft.com/en-us/dotnet/standard/base-types/custom-date-and-time-format-strings
But are you sure that the value is not stored as DateTime? Check by using ds.Tables["VOUCHER"].Rows[0].Field<DateTime>("BASICDATETIMEOFINVOICE"). Then no conversion from Object to string to DateTime is needed. If not you should consider to store it as DateTime in the first place, wherever the DataTable was filled from.

String yy-MM-dd HH:mm:ss.SSS convert to datetime in C# [duplicate]

How can convert this string yy-MM-dd HH:mm:ss.SSS to datetime in c#?
You can use the DateTime.ParseExact() method and define the exact format string that you are expecting to receive :
// This will parse a DateTime object using the "yy-MM-dd HH:mm:ss.fff" format
var date = DateTime.ParseExact(input,"yy-MM-dd HH:mm:ss.fff", null);
This assumes that the Y characters will represent a two-digit year and the S characters you were looking for would be considered fractional seconds, which have been converted to the y and f formats respectively.
Example
You can see a working example of this here.
