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.

Explain in your own words why you cannot pass additional arguments in a function after using the params keyword.

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?

Because if you could you wouldn't have homework to do.

Not sure how C# implement that, but I'm guessing it has to do with how the arguments are push onto a stack before a function address is invoked. Being that the stack doesn't have anything to manage what type each parameter are and the Parameter type can be any number of arguments, making it difficult to separate the actual arguments from the Parameter ones.
