c#如何通过点击数据网格中的按钮从数据网格中获取数据？

using System;
using System.Windows.Forms;
using System.Data;

namespace DataGridViewExample
{
    public partial class Form1 : Form
    {
        private DataTable dataTable;

        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            // 创建一个DataTable并添加数据
            dataTable = new DataTable();
            dataTable.Columns.Add("ID", typeof(int));
            dataTable.Columns.Add("Name", typeof(string));
            dataTable.Rows.Add(1, "John");
            dataTable.Rows.Add(2, "Jane");

            // 将DataTable绑定到DataGridView
            dataGridView1.DataSource = dataTable;

            // 添加一个按钮列
            DataGridViewButtonColumn buttonColumn = new DataGridViewButtonColumn();
            buttonColumn.HeaderText = "操作";
            buttonColumn.Text = "获取数据";
            buttonColumn.UseColumnTextForButtonValue = true;
            dataGridView1.Columns.Add(buttonColumn);
        }

        private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
        {
            // 检查是否点击了按钮列
            if (e.ColumnIndex == dataGridView1.Columns["操作"].Index && e.RowIndex >= 0)
            {
                // 获取对应行的数据
                int id = (int)dataGridView1.Rows[e.RowIndex].Cells["ID"].Value;
                string name = (string)dataGridView1.Rows[e.RowIndex].Cells["Name"].Value;

                // 在控制台输出获取到的数据
                Console.WriteLine("ID: " + id);
                Console.WriteLine("Name: " + name);
            }
        }
    }
}
