ref vs. out keyword

[Yaakov Davis]

What are the differences, if any? Thanks, Yaakov

When using out, the parameter needn't be initialized before being passed to into the method, and it must be assigned a value before the method exits. If you need more info, I'd suggest looking in the docs[^]. Charlie if(!curlies){ return; }

Thanks a lot. Actually, I've read rhe docs before, but I didn't notice this difference. Yaakov.

int a,b,c,d,e,f,g = foo(out a, out b, out c, out d, out e, out f);

vs

int a,b,c,d,e,f;
a=b=c=d=e=f=0;
int g = foo(ref a, ref b, ref c, ref d, ref e, ref f);

so, about 2 lines :-> top secret

Nice! I didnt know that one. But I wonder if it is good style to declare more than one variable on one line. Most coding styles would forbid it.
