Question

我的UserController.cs文件中的ASP.Net MVC 5 App出现错误。我得到的错误是CS1503，但与其他问题/解决方案相比，原因没有道理。

完整错误是：

CS1503参数1：无法在第25行从“ Elevate_Your_Pitch.Models.tblRegistration”转换为Elevate_Your_Pitch.Models.user”

下面将为我的UserController.cs（控制器），tblRegistration.cs（模型）和Registration.Context.cs（edmx）文件提供代码：

UserController.cs

using System;
using Stystem.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.MVC;
using Elevate_Your_Pitch.Models;

namespace Elevate_Your_Pitch.Controllers
{
  public class UserController : Controller
  {
    // Get: User
    public ActionResult Index() { return View(); }

    [HttpPost]
    public ActionResult Index(tblRegistration obj)
    {
        if (ModelState.IsValid)
        {
            elevate_your_pitchEntities db = new elevate_your_pitchEntities();
            db.users.Add(obj); //This is line 25 and (obj) is causing the error
            db.SaveChanges();
        }
        return View(obj);
    }
  }


}

namespace Elevate_Your_Pitch.Models
{
  using System;
  using System.Data.Entity;
  using System.Data.Entity.Infrastructure;

  public partial class elevatey_your_pitchEntities : DbContext
  {
       public elevatey_your_pitchEntities() : base("name=elevatey_your_pitchEntities")
       {
       }

       protected override void OnModelCreating(DbModelBuilder modelBuilder)
       {
          throw new UnintentionalCodeFirstException();
       }

       public virtual DbSet<user> users { get; set; }
  }
}

tblRegistrations.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.ComponentModel.DataAnnotations.Schema;
using System.ComponentModel.DataAnnotations;

namespace Elevate_Your_Pitch.Models
{
  [Table("user")]
  public partial class tblRegistration
  {
      [Key]
      public int UserID { get; set;  }
      public string FirstName { get; set; }
      public string LastName { get; set; }
      public string EmailID { get; set; }
      public DateTime DateOfBirth { get; set; }
      public string Password { get; set; }
      public string IsEmailVerified { get; set; }
  }
}

我想念什么吗？这没有道理。

Answer 1

对我来说，我解决了此错误，我发现2个同名类的注册类，我更改了一个，并保留了一个类名Registration及其工作。

db。[table] .Add（obj）无法转换。错误代码CS1503
