用DataTable显示数据源（自己根据需要构造出来的）

DataTable dt = new DataTable();
int i;
dt.Columns.Add("设备编号");
dt.Columns.Add("Command类型");
dt.Columns.Add("Command");
dt.Columns.Add("Command时间");
dt.Columns.Add("类型");
dt.Columns.Add("状态");
dt.Columns.Add("更新时间");
foreach (var item in list)
{
DataRow dr = dt.NewRow();
i = 0;
/*下面有些对数据格式转换的函数*/
dr[i++] = MycConvert.ToString(item.M_DeviceInfo.DevI_NO);
dr[i++] = _DeviceCommandTypeData.GetKey(item.M_UpdateDeviceCommandJob.UDCJ_CommandType.ToString());
dr[i++] = _DeviceCommandCodeData.GetKey(item.M_UpdateDeviceCommandJob.UDCJ_CommandCode.ToString());
dr[i++] = MycConvert.ToDateTimeString(item.M_UpdateDeviceCommandJob.UDCJ_CommandTime);
dr[i++] = _DeviceJobRealTimeData.GetKey(item.M_UpdateDeviceCommandJob.UDCJ_IsRealTime.ToString());
dr[i++] = _DeviceJobStateData.GetKey(item.M_UpdateDeviceCommandJob.UDCJ_State.ToString());
dr[i++] = MycConvert.ToDateTimeString(item.M_UpdateDeviceCommandJob.UDCJ_UpdateTime);
dt.Rows.Add(dr);
}
dataGridView1.DataSource = dt;
