我正在尝试将数据从MVC注册表单保存到Visual Studio本地数据库中，但是我没有将数据保存到数据库中。任何帮助将不胜感激。
在我的另一个项目中，数据已正确存储在本地数据库表中
HomeController：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using OQT_P1._2.Models;
namespace OQT_P1._2.Controllers
{
public class HomeController : Controller
{
public ActionResult Index()
{
return View();
}
public ActionResult Contact()
{
return View();
}
[HttpPost]
[ActionName("Contact")]
public ActionResult Contact_Post()
{
Contact contact = new Contact();
TryUpdateModel(contact);
if (ModelState.IsValid)
{
AddComment(contact);
return RedirectToAction("Registration");
}
return View();
}
public ActionResult AddComment(Contact c)
{
OQContext db = new OQContext();
db.Contacts.Add(c);
db.SaveChanges();
return View();
}
[HttpGet]
[ActionName("Registration")]
public ActionResult Registration_Get()
{
return View();
}
[HttpPost]
[ActionName("Registration")]
public ActionResult Registration_Post()
{
Registration register = new Registration();
TryUpdateModel(register);
if (ModelState.IsValid)
{
AddStudent(register);
return RedirectToAction("Registration");
}
return View();
}
public ActionResult AddStudent(Registration r)
{
OQContext db = new OQContext();
db.Registrations.Add(r);
db.SaveChanges();
return View();
}
}
}
