Hi Pooja,
You may use mathematics set theory.
perform union and intersect of both array then
difference of both result is your out put. see below sentence
array[]c = a.Union(b).Except(a.Intersect(b)).ToArray()
Or you may use step by step
var a1 = array1.Union(array2);
var a2 = array1.Intersect(array2);
var result = a1.Except(a2).ToArray();

Hello,
Posting home-work assignments as questions in forums and getting answers is probably not a very good way to learn programming.
These questions are given to check if you can pick-up appropriate language construct to solve it.
I sincerely believe that you are defeating the whole purpose of it and making serious damage to yourself.
In the end, I am very well aware that it is none of my business.

Hi Pooja,
You can try this..
----------------------------------------------------------------
int[] arry1 = new int[5] { 1, 2, 3, 4, 5 };
int[] arry2 = new int[5] { 5, 4, 3, 9, 7 };
List lst = new List();
for (int i = 0; i < arry1.Length; i++)
{
if ( ! arry2.Contains(arry1[i]))
{
lst.Add(arry1[i]);
}
}

for (int i = 0; i < arry2.Length; i++)
{
if (!arry1.Contains(arry2[i]))
{
lst.Add(arry2[i]);
}
}
var message = "Array Contains \n " + string.Join(Environment.NewLine, lst.ToArray());
MessageBox.Show(message);
