Form1：
public static string[] a; private void dataGridView1_DoubleClick(object sender, EventArgs e)//添加datagridview1的双击事件 { try { int index = dataGridView1.CurrentRow.Index; a = new string[dataGridView1.ColumnCount]; for (int i = 0; i < dataGridView1.ColumnCount; i++) { a[i] = dataGridView1.Rows[index].Cells[i].Value.ToString(); } Form2 f2 = new Form2(); f2.Show(); } catch { } }Form2:// public Form2() { InitializeComponent(); showGridView(); } private void showGridView() { dataGridView1.Rows.Add(tb); for (int i = 0; i < dataGridView1.ColumnCount;i++ ) dataGridView1.Rows[dataGridView1.RowCount-2].Cells[i].Value = Form1.a[i];//根据AllowUserToAddRow属性选择最后一行，true时dataGridView1.RowCount-2,false时dataGridView1.RowCount-1 }winform中如何选中datagridview中的一行数据双击后跳转并将其显示在另一个页面的datagirdview中
