Explain in your own words why you cannot pass additional arguments in a function after using the params keyword.
- because the compiler forbade it? - because
Method<T>(params T[] values1, params T[] values2, params T[] values3)is a problem and hassel to understand without benefit?All in one Menu-Ribbon Bar DirectX for WinRT/C# since 2013! Taking over the world since 1371!

Why can't you read the friendly manual[^]?
In Word you can only store 2 bytes. That is why I use Writer.
Actually, the "friendly manual" isn't answering his question. It only confirms the statement in the assignment that you cannot add any parameters after the params keyword, but not why! :doh: Unless of course "B'cause Microsoft says so!" is an acceptable answer to the question... :rolleyes:

Because params is an array of undetermined length. If you write:
void Foo(params int[] ints)and try to call it with:Foo(1, 2, 3, 4)How would it know that you want 4 as a separate argument, if the method were defined like this:void Foo(params int[] oneThroughThree, int fourth)OK, maybe it could use type information, but that leads to bottomless pits where the Wumpus will eat you.

I realised I was "helping" you with an assignment which actually was the opposite of helping - because it made thinking on your part unneccessary. Help should be given in a way that pushes the learner into the right direction, lifting confusion, but not presenting the answer right away. Confucius is attributed to have said: Tell me and I forget Show me and I remember Let me do it and I understand. If you have trouble with an assignment, don't ask for the answer. Try to make it clear to yourself why you can't answer it and ask people to help you better understand the assignment so that you can answer it yourself.

What part of "in YOUR own words" do you not understand? When the tests come around do you get to go on the 'net and ask people for the answers? Congratulations on failing your class!

Nice try, but
void Foo(params int[] oneThroughThree, int fourth)
would need to be called like this:
Foo(new int[] {1,2,3},4);
would it not?
