Example of practical of "ref" use

Asked 2011-01-10T11:07:33.700

I am struggling how to use "ref" (to pass argument by reference) in real app. I would like to have simple and mainly meaningful example. Everything I found so far could be easily redone with adding return type to the method. Any idea someone? Thanks!

I think a good example would be trampolining.

This is where you take a recursive function and rework it to a method that is repeatidly called on a set of values. The reason being that instead of going into the stack very deeply the stack remains flat because you return after every call instead of calling yourself.
