I have tried to get UTC format datetime in c# and tried with below code but not able to get proper value.

string ddd = "2018-02-28T18:10:13+08:00";
DateTime dt = new DateTime();
dt = Convert.ToDateTime(ddd);
//var datetime = new DateTime(dt, DateTimeKind.Local);
var text = dt.ToString("o");
Console.WriteLine(text);
//2018-02-28T15:40:13.0000000+05:30

Getting this value : //2018-02-28T15:40:13.0000000+05:30
need to remove 0000000 from date.

What I have tried:

string ddd = "2018-02-28T18:10:13+08:00";
DateTime dt = new DateTime();
dt = Convert.ToDateTime(ddd);
//var datetime = new DateTime(dt, DateTimeKind.Local);
var text = dt.ToString("o");
Console.WriteLine(text);
//2018-02-28T15:40:13.0000000+05:30
Console.ReadKey();

When you're dealing with values that have a UTC offset, you should use DateTimeOffset[^] instead of DateTime.

Or, if you want proper control, use NodaTime[^].

You can't "remove the 0000000 from the date" - DateTime values don't work like that, they are stored as a number of ticks since a particular moment in time, so you can't dump the ticks!

But you can format the output:

C#

string text = dt.ToString("s");

Will give you the UTC format:

2018-02-18T12:10:13

UTC does not have a timezone, so it wouldn't be "+05:30"
But this will add it:

C#

string text = dt.ToString("yyyy-MM-ddTHH:mm:ssK");
