C# code

DialogResult dlResult = MessageBox.Show(this, "要删除这些记录吗？", "请确认", MessageBoxButtons.YesNo, MessageBoxIcon.Question);                if (dlResult == DialogResult.Yes)                {                    try  {  string connString = "Server=10.10.0.5;Database=xianggelia;User Id=sa;Password=12345678;";  string sql = "delete from EquManager where 1=1";  if (dataGridView1.CurrentRow.Selected)  {  sql = sql + "and Id=" + Convert.ToInt32(dataGridView1.CurrentRow.Cells[0].Value.ToString());  }  int n = 0;  SqlConnection conn = new SqlConnection(connString);  SqlCommand cmd = new SqlCommand(sql, conn);  conn.Open();  n = cmd.ExecuteNonQuery();  conn.Close();  if (n < 0)  {  label1.Text = "删除成功";  }  else  {  label1.Text = "删除失败";  }  }  catch (Exception ex)  {  MessageBox.Show("开啥子玩笑，删啥呢！", "提示");  return;  throw ex;  }  Refresh();  shuliang.Text = "当前数量为：" + dataGridView1.Rows.Count.ToString();                }
