int[] array1 = { 7,8,6,1,1,3,2,2,7,6,3,8,7 };
Array.Sort(array1);
array1.Reverse();
int[] NewArr = new int[array1.Length];
int n,j = 0;
for (int i = 0; i <= array1.Length - 2; i++)
{
if (array1[i] != array1[i + 1])
{
NewArr[j] = array1[i];
j++;
}
}
NewArr[j] = array1[array1.Length - 1];
for (n = 0; n <= j; n++)
{
Console.WriteLine("New array " + NewArr[n]);
}
