I want to translate text (string and date both) from English language to Spanish language in C#. The text ill get will be dynamic so it can be anything. Can anyone please suggest as to how this can be done.

Also i don't want restrictions regarding number of characters allowed as text may have more characters.
If number of characters allowed has a limit then it would be better that it is large enough.

What I have tried:

I tried looking into various solutions to this on Internet but seems that only static text has been converted or translated to a different language. I need to do this with dynamic texts.
