为了更好的参考，请查看::

How to Combine two models into a single model and pass it to view using asp.net MVC razor

然后在服务器端的表单提交（即进入控制器的操作）中保存来自视图的数据，如::

public ActionResult Save(CommonViewModel common)
    {
        var FirstModel = new FirstModel();
        FirstModel = common.FirstModel;
        db.Entry(FirstModel).State = EntityState.Added;

        var SecondModel = new SecondModel();
        SecondModel = common.SecondModel;
        db.Entry(SecondModel).State = EntityState.Added;
        db.SaveChanges();
    }

[HttpPost]

    public ActionResult Edit(CompPeripheral cp, int c_id,int em_id,int asset_id)
    {
        if (ModelState.IsValid)
        {
            cp.Compconfig.c_id = c_id;
            cp.Compconfig.em_id = em_id;
            cp.Compconfig.asset_id = asset_id;
            db.tbl_compconfig.Add(cp.Compconfig);
            db.SaveChanges();
            var id = db.tbl_compconfig.Max(a => a.comp_id);
            cp.Comperipheral.comp_id = id;
            //saving Comp Peripheral in database
            db.tbl_comperipheral.Add(cp.Comperipheral);
            db.SaveChanges();
            return RedirectToAction("Index");
        }

        ViewBag.asset_id = new SelectList(db.tbl_assetm, "asset_id", "asset_name", cp.Compconfig.asset_id);
        ViewBag.em_id = new SelectList(db.tbl_employee, "em_id", "em_fullname", cp.Compconfig.em_id);
        ViewBag.c_id = new SelectList(db.tbl_client, "c_id", "c_name", cp.Compconfig.c_id);
        return View(cp);
    }
