用datatable处理DataGridView比较方便，但是今天在帮朋友做时，没用数据库，用的List集合去做了，结果发现List集合不能转为datatable

private void button1_Click(object sender, EventArgs e)
        {

            DataTable dt = new DataTable();
            DataTable dt2 = new DataTable();
            dt2.Columns.Add("Name");
            dt2.Columns.Add("Age");
            for (int i = 0; i < dataGridView1.SelectedRows.Count; i++)
            {
                DataRow dr = dt2.NewRow();
                dr["Name"] = dataGridView1.SelectedRows[i].Cells[0].Value;
                dr["Age"] = dataGridView1.SelectedRows[i].Cells[1].Value;
                dt2.Rows.Add(dr);
            }
            Form2 fr = new Form2(dt2);
            fr.Show();
        }
        private void Form1_Load(object sender, EventArgs e)
        {
            List<person> list1 = new List<person>
            {
                new person{Name="123",Age=12},
                new person{Name="234",Age=12}
            };
            dataGridView1.DataSource = list1;
        }
    }
}
