Can someone tell me what Date Time format this string is

Question

I am being passed this, 2022-11-01T00:00:00, Date Time as a string. I need to convert it to a DateTime in C# but cannot seem to figure out what exact format the string is in.

I have tried many variations of the following but continue to get String was not recognized as a valid DateTime.

Here is the latest code I have tried:

DateTime test = DateTime.ParseExact(startTime, "yyyy-MM-ddTHH:mm:ssZ", CultureInfo.InvariantCulture);

This appears to be with how the data is being sent to my software. I tried the suggestions below but am still receiving the same error message.

Answer 1

Is there an offset you are trying to account for? I noticed you have a Z at the end of your DateTime format in the latest code you have tried. Removing it in this block of code made it parseable.

string startTime = "2022-11-01T00:00:00";
DateTime test = DateTime.ParseExact(startTime, "yyyy-MM-ddTHH:mm:ss", CultureInfo.InvariantCulture);
Console.WriteLine(test.ToString()); // 11/1/2022 12:00:00 AM

See https://learn.microsoft.com/en-us/do.net/standard/base-types/standard-date-and-time-format-strings

string text = "2022-11-01T00:00:00";

if (DateTime.TryParseExact(text, "yyyy-MM-ddTHH:mm:ss", null, System.Globalization.DateTimeStyles.AssumeUniversal, out DateTime dt))
{
    Console.WriteLine(dt.ToString("u"));
}
else
{
    Console.WriteLine("bad");
}
