Q:

How to say "as you wish" in Chinese

I want to know what to say in the following scenario: I am pushing someone for his own good, and he is not doing what I want, so I would then say to him "Okay, as you wish." How can I express this in Chinese? 

Update: 如你所愿（rúnǐsuǒyuàn）from Google Translate is not understood as having the same meaning by Chinese speakers.

A:

I think that “随你便” may suit your needs.  This phrase can be translated as "as you wish" or "suit yourself" or even "whatever."
