Please make an attempt to do your homework yourself first, then if you run into problems you can get great help here. You'll be a much better developer in the future if you learn to analyze your problems first.

Solution 1

Can you use Linq?

C#

int[] Arr1 = { 10, 20, 30, 50, 60 };
int[] Arr2 = { 10, 20, 30 };
int[] Arr3 = Arr1.Except(Arr2).ToArray();

It is a very good solution, but if questions look like homework like this one does, we discourage providing the code to the OP unless they provide us some indication that they have attempted something. We usually encourage them to show us what they have tried and where they encounter problems. +5 for a very concise and accurate answer!

Totally agree. I observe how in some Inquirers the seduction of easy answers blocks any chances to learn anything. I deny to answer is some apparent cases, explain why.

Actually, I considered the possibility it was a homework assignment. But I've never seen a programming assignment have an answer that simple. If it is homework, his teacher will probably reject the use of Linq and make him iterate the arrays.
