我希望有人能帮助我。

需要时将提供更多信息。

您的方法接受2个参数，但您只发布1个对象-

列表

。假设您要基于现有DeviceConfig构建新的DeviceConfig，则应将操作方法更改为以下内容：

public ActionResult Edit(List<Device_Pricelist> device_Pricelists)
{
    if (ModelState.IsValid)
    {
        try
        {
            var deviceConfig = db.DeviceConfig.Find(device_Pricelists.First().Device_config_id);
            deviceConfig.device_type_id = 13;
            deviceConfig.Active = true;
            deviceConfig.VersionNr++;
            deviceConfig.Date = DateTime.Now;

            db.DeviceConfig.Add(deviceConfig);

            foreach(var item in device_Pricelists)
            {
                item.Device_config_id = deviceConfig.Device_config_id;
            }

            db.Device_Pricelists.AddRange(device_Pricelists);

            db.SaveChanges();
            TempData["SuccesMessage"] = "Data is Succesfully saved";
            return RedirectToAction("Index");
        }
        catch
        {
            TempData["AlertMessage"] = "Saving Data Failed, Try Again";
        }
    }
    return View(device_Pricelists);
}

Sry，我添加了错误的代码，现在添加了正确的代码。你说了你想要的，但你没有解释要修复什么？当前代码有什么问题？您希望它做什么？@ChetanRanpariya当前的问题是创建了一个新的配置id，但没有相应的数据（需要修复），并且设备配置数据被添加到旧的配置id。新版本NR也没有正确更新
