how to convert UTC time to Local using C#?


Hello, I would like to know how can I convert UTC datetime into local (user's pc) datetime in asp.net MVC razor page using C#?

I thought .ToLocalTime() should work, but I am not getting correct result.

Here are the possible methods to convert UTC time into Local using C#

  1. Using TimeZone.CurrentTimeZone.ToLocalTime(UTCDateTime);
  2. Using UTCDateTime.ToLocalTime(); (Should work)
  3. When Format is known using DateTime.ParseExact
    1. DateTime.ParseExact(dateString, 
                         "MM/dd/yyyy HH:mm:ss", 
                         CultureInfo.InvariantCulture, 
                         DateTimeStyles.AssumeUniversal | DateTimeStyles.AdjustToUniversal)

      In the above code, we have considered that Datetime format is known to us

  4. Using TimeZoneInfo.ConvertTimeFromUtc(UTCDatetime, TimeZoneInfo.Local)

Any of the above ways should work.

You can also try something like this

// Coordinated Universal Time string from 
		// DateTime.Now.ToUniversalTime().ToString("u");
		string date = "2022-02-11 16:13:00Z"; 
		// Local .NET timeZone.
		DateTime localDateTime = DateTime.Parse(date); 
		DateTime utcDateTime = localDateTime.ToUniversalTime();


		string meTimeZoneKey = "Middle East Standard Time";
		TimeZoneInfo meTimeZone = TimeZoneInfo.FindSystemTimeZoneById(meTimeZoneKey);
		DateTime meDateTime = TimeZoneInfo.ConvertTimeFromUtc(utcDateTime, meTimeZone);
		Console.WriteLine(meDateTime); 


//output: 2/11/2022 6:13:00 PM
