Using CultureInfo.CurrentCulture.TextInfo.ToTitleCase is a good attempt to simplify capitalization, but it won’t fully work for Jaden Case in this context. ToTitleCase capitalizes the first letter of each word but does not affect subsequent letters. For example, ToTitleCase("hELLO wORLD") would result in "HELLO WORLD", which isn’t what Jaden Case requires. Jaden Case should only capitalize the first letter of each word and keep the rest in lowercase.

To fix this, you can convert the phrase to lowercase first, ensuring only the first letter of each word is capitalized:

CultureInfo.CurrentCulture.TextInfo.ToTitleCase(phrase.ToLower());

Would this not work with words like "of" or "the"?

The solution is not suitable for cases where the user suddenly wants to write a word through Caps Lock

Hm, very very clever.

Damn.

This solution does in one line what mine did in two.

Clever and elegant solution!

I ran your code in visual studio.net 2015. I input null string and there is an error. Is there anything I missed running your code correctly in my computer? I'm just a newbie in C#.
