DataGridView

간단한 실습 예제 

 

 public partial class Form1 : Form
    {
        List<Cafe> aList;
        public Form1()
        {
            InitializeComponent();
            aList = new List<Cafe>
            {
                  new Cafe() { Name = "아메리카노", Price = 1500 },
                  new Cafe() { Name = "라떼는 말야", Price = 3000 },
                  new Cafe() { Name = "녹차 프라푸치노", Price = 3500 },
                  new Cafe() { Name = "아아메리카노", Price = 2000 },
                  new Cafe() { Name = "에스프레소", Price = 1500 }
            };

            dataGridView1.DataSource = aList;

        }

    }

    class Cafe
    {
        public string Name { get; set; }
        public int Price { get; set; }
