difference between ref and out C#
When passing a variable by ref you must have the variable initialized first. Example:
int num = 0; setNum(ref num); When passing a variable by out you do not have to have the variable initialized. Example: int num; setNum(out num); In conclusion they both pass a variable by reference. If you are going to use the ref keyword initialize it or you will get a error! else just use out
