Program for count a total no of duplicate element in given dynamic array.

Hi,

This program is for count a total no of duplicate element in given array values. 

Hope this is helpful for you.

   class Program

    {

        static void Main(string[] args)

        {

            int input = 0;

            int[] arrayvalue = new int[] { };

            int[] Temp_array = new int[] { };

            int[] duplicate_array = new int[] { };

            Console.Write("Enter no of object that you want to display:-");

            input = Convert.ToInt32(Console.ReadLine());

            arrayvalue = new int[input];

            Temp_array = new int[input];

            duplicate_array = new int[input];

            int DuplicateCount = 0;

            for (int i = 0; i <= arrayvalue.Length - 1; i++)

            {

                Console.Write("Element at {0} - ", i);

                arrayvalue[i] = Convert.ToInt32(Console.ReadLine());

            }

            for (int k = 0; k <= arrayvalue.Length - 1; k++)

            {

                int count = 0;

                if(Temp_array.Length == 0 || !Temp_array.Contains(arrayvalue[k]))

                {

                    Temp_array[k] = arrayvalue[k];

                }

                else

                {

                    duplicate_array[k] = arrayvalue[k];

                }

            }

            Array.Clear(Temp_array,0,input);//Clear array

            Console.WriteLine("----------------------");

            for (int j =0;j<duplicate_array.Count();j++)

            {

                //get list of duplicate element in an array.

                if (duplicate_array[j] != 0 && !Temp_array.Contains(duplicate_array[j]))

                {

                    Temp_array[j] = duplicate_array[j];

                    DuplicateCount++;

                }

            }

            Console.WriteLine("The total no of duplicate element is - {0}:",DuplicateCount);

            Console.ReadLine();

        }

    }

 For Ex input :1,2,1,2,1

 output:The total no of duplicate element is 2.
