statistical program in C#

Create a statistical program which will allow the user to:

• Add new data
• See all data entered
• Find an item, to see whether it has been entered or not

View a summary of statistics: amount of data, 

1. sum
2. average 
3. maximum
4. minimum
5. Exit the program

These options must appear on a menu. Each option will be chosen by a number or a letter. The program must reserve space for a maximum of 1000 data, but keep count of how many data actually exist.

Solution:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace Statistics
{
    class Program

        static void Main(string[] args)

            bool found = false;
