在asp.net mvc中更新后返回原始页面

Question

如果某列为空，我有一个 asp.net MVC 从表中选择 10 行数据，并允许更新该列。 每次更新后，我都希望它返回显示的原始 10，而不是进行新的选择。因为我想让它让我看看更新是否成功。

这是我当前的代码。

 using System;
using System.Collections.Generic;
using System.ComponentModel.Design;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using DBUpdateTool.Models;

namespace DBUpdateTool.Controllers
{
    public class HomeController : Controller
    {
        private dtsdbEntities _db = new dtsdbEntities();
        public ActionResult Index()
        {
            return View(_db.IPR_CompanyGen.Where(c => c.ACCOUNT_ID == null).Take(10).ToList());
        }

        public ActionResult Edit(int id)
        {
            var CompanyToEdit = (from m in _db.IPR_CompanyGen where (m.CompanyID.Equals(id.ToString())) select m).First();
            return View(CompanyToEdit);
        }


        // GET: Home/Edit/5
        [HttpPost]
        public ActionResult Edit([Bind(Include = "CompanyID,CompanyName,Address1,Address2,Address3,City,StateProvinceCode,PostalCode,CountryCode,Region,PhoneNumber,URL,PrimaryCompanyType, DominantCompanyStyle,   DominantCompanyOrientation, Buy_side,   Sell_side,  Strategic,  EqPortfolioTurnover,    ReportedEquityAssets,   Status, LastModifiedDate,   ACCOUNT_ID, CRM_Comments")] IPR_CompanyGen CompanyToEdit)
        {

            if (ModelState.IsValid)
            {
                var OriginalCompany = (from m in _db.IPR_CompanyGen where (m.CompanyID.Equals(CompanyToEdit.CompanyID.ToString())) select m).First();
                OriginalCompany.ACCOUNT_ID = CompanyToEdit.ACCOUNT_ID;

                _db.Entry(OriginalCompany).CurrentValues.SetValues(OriginalCompany);
                _db.SaveChanges();

                 return View(OriginalCompany);
            }
            return View();
        }



    }

    internal class DBEntities
    {

    }
}

而不是return RedirectToAction("Index");放

return View(OriginalCompany);
