【问题标题】：Asp.net MVC Saving Data from other tables to the Source TableAsp.net MVC 将数据从其他表保存到源表
【发布时间】：2022-10-20 14:29:37
【问题描述】：

我创建了一个表单，它接受用户的输入并将其保存到tblFuelTroubleTickets，例如，我将其他表中的一些字段填充为下拉列表网站将所有站点详细信息与 ClusterOwners 一起存储，这两个表都已连接。

enter image description here

附件是我从用户那里获取一些参数但我不想使用的表格集群所有者名称从用户作为网站存储所有站点详细信息，因此当用户选择站点ID该程序必须从网站并将其保存到tblFuelTroubleTickets以及其他输入细节。

这是视图

@model MyTempWorking.Models.TTCreateModel

@{
     Layout = null;

    if (Session["userID"] == null)
    {
        Response.Redirect("~/Login/Index");
    }
 }

这是控制器

[HttpGet]
public ActionResult CreateTT()
{
     List<tblClusterOwner> list = db.tblClusterOwners.ToList();
     ViewBag.Cuslname = new SelectList(list, "ClusterOwnerCode", "ClusterOwnerName");
     List<tblSiteCPStatu> list2 = db.tblSiteCPStatus.ToList();
     ViewBag.Cpname = new SelectList(list2, "CPStatusCode", "CPStatus");
     List<tblSite> list3 = db.tblSites.Where(x => x.Active==true).ToList();
     ViewBag.sitec = new SelectList(list3, "SiteCode", "SiteID");
     List<tblSiteVisitType> list4 = db.tblSiteVisitTypes.ToList();
     ViewBag.sitevc = new SelectList(list4, "VisitCode", "VisitName");
     return View();
 }


[HttpPost]
public ActionResult CreateTT(tblFuelTroubleTicket fctt)
{   
     db.tblFuelTroubleTickets.Add(fctt);            
     fctt.CreatedDate = DateTime.Now;
     fctt.CreatedBy = User.Identity.Name;
     fctt.IsActive = true;
     //fctt.AreaCode=            
     db.SaveChanges();
     return RedirectToAction("DisplayTTs");
 }

【解决方案1】：

所以现在我可以将 excel 放入 HTML 表中。

[1]：https://i.stack.imgur.com/sv09f.png

<table>
  <thead>
       <tr>
        <td>ID</td>
        <td>Product Name</td>
      </tr>
  </thead>

  <tbody>
      <tr>
       <td>1234</td>
       <td>Prod1199</td>
     </tr>
     <tr>
       <td>1235</td>
       <td>Prod1200</td>
     </tr>
and so on......

  </tbody>
</table>

那么我怎样才能将它发送到控制器并检查 ID 在 SQL 表中是否可用，如果可用，然后更新产品名称
