Hello.

I working now on firm that using ref in every function.
The reason, is to catch errors.
There example :

//return true if the read is success
//otherwise writing to the error ,the problem 
bool ReadFile(ref string error)

Question:
How do you catching errors?
Using ref,exceptions or other way?
