索引超出了数组界限

                    string sqlBridge = string.Format("SELECT COUNT(DEVICEID) AS COUNT FROM DEVICE WHERE ORGID='{0}'", dataGridViewMain.Rows[index].Cells[0].Value.ToString());
                    SqlCommand cmd = new SqlCommand(sqlBridge, con);
                    ArrayOfDeviceElement[] Bridge = new ArrayOfDeviceElement[length];
                    SqlDataReader sr = cmd.ExecuteReader();
                    sr.Read();
                    length = Convert.ToInt16(sr["COUNT"]);
                    sr.Close();

                    sqlBridge = string.Format("SELECT DEVICE.NAME AS NAME,DEVICE.DEVICEID AS DEVICEID,DEVICEPRODUCT.NAME AS TYPE FROM DEVICE,DEVICEPRODUCT WHERE DEVICE.PRODUCTID=DEVICEPRODUCT.PRODUCTID AND ORGID='{0}'", dataGridViewMain.Rows[index].Cells[0].Value.ToString());
                    cmd = new SqlCommand(sqlBridge, con);
                    sr = cmd.ExecuteReader();
                    while(sr.Read()&&++i<length)
                    {
                        try
                        {
                            Bridge[i].Name = sr["NAME"].ToString();
                            Bridge[i].CoordinateX += 100;
                            Bridge[i].CoordinateY += 100;
                            Bridge[i].DeviceId = sr["DEVICEID"].ToString();
                            Bridge[i].DeviceType = sr["TYPE"].ToString();
                        }
                        catch (Exception ex)
                        {
                            MessageBox.Show(ex.Message);
                        }
                    }
                    sr.Close();
问题在index上，index是点击dataview获取的 --------------------编程问答-------------------- dataGridView 好像有一个selectindex吧？怎么不用那个!  还有就是你自己打印一下这个dataGridView的总行数和你的index比较一下 --------------------编程问答-------------------- 单步调试 --------------------编程问答-------------------- 调试，所有带 [] ,的地方特别注意

补充：.NET技术 ,  .NET Framework
