How to declare and use a simple struct (value type) in C#

Answer 1

using System;

namespace ConsoleApplication1
{
    public struct Point
    {
        public int X, Y;
    }
    class Program
    {
        static void Main(string[] args)
        {
            try
            {
                Point p1 = new Point();

                p1.X = 12;

                Point p2 = p1; // copy

                Console.WriteLine(p1.X); // 12
                Console.WriteLine(p2.X); //12

                p1.X = 30;
                Console.WriteLine(p1.X); // 30
                Console.WriteLine(p2.X); // 12
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }
        }
    }
}
