C # convert datetimeoffset to string with milliseconds

Question

The toString () method by default in datetimeoffset converts time to string format, but loses milliseconds. Is there any way to save it?

Answer 1

ToString() takes a format argument. There are existing string format codes that will print milliseconds - see here.

For example, the format code “o” will print the complete time line with milliseconds, or you can create your own format string to suit your needs and use the “ffff” specifier to add milliseconds where necessary.

 myDateTime.ToString("o") 

Answer 2

You must use "ffff" in string format to get miliseconds, for example:

 DateTime date = DateTime.Now; string strDate = String.Format("{0:dd.MM.yyyy hh:mm.ss:ffff}", date);

Answer 3

According to the documentation of DateTimeOffset , this behaves in most ways similar to ToString DateTime . This means that you can, for example, use the standard format string o , which shows milliseconds, or you can use any custom format template that you want.

So you can do this:

 Console.WriteLine(dto.ToString("o")); 

Answer 4

You can do this using the f character in your format string.

 DateTimeOffset.Now.ToString("ddMMyyy-HH:mm:ss") 

Gives "23032011-16: 58: 36"

 DateTimeOffset.Now.ToString("ddMMyyy:HHmmssffff") 

Gives "23032011-16: 59: 088562"
