namespace WindowsFormsApp1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            // 获取搜索文本
            string searchText = textBox1.Text;

            // 使用LINQ查询搜索匹配的单元格数据
            var query = from DataGridViewRow row in dataGridView1.Rows
                        where row.Cells["Column1"].Value.ToString().Contains(searchText)
                        select row;

            // 将查询结果应用于DataGridView控件
            dataGridView1.DataSource = query.CopyToDataTable();
        }
    }
}
