C# 如何修复此本地主机页可以’；在asp.net中找不到

我想从razor页面向控制器发送一个ID，获取关于该ID的信息并对其进行编辑，但出现了一个错误

我使用Ado.net技术

这是我的创业：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.AspNetCore.Session;


namespace WebApplication7
{

public class Startup
{
    public Startup(IConfiguration configuration)
    {
        Configuration = configuration;
    }

    public IConfiguration Configuration { get; }

    // This method gets called by the runtime. Use this method to add services to the container.
    public void ConfigureServices(IServiceCollection services)
    {
        services.AddMvc();
        services.AddDistributedMemoryCache();
        services.AddSession();
    }

    // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
            app.UseBrowserLink();
        }
        else
        {
            app.UseExceptionHandler("/Home/Error");
        }

        app.UseStaticFiles();           
        
        
        app.UseSession();

        app.UseMvc(routes =>
        {
            routes.MapRoute(
                name: "default",
                template: "{controller=Home}/{action=Index}/{id?}");
        });

       


    }
}
}

这是我的观点：

欢迎任何回复。

什么是错误？是ASP.NET核心MVC吗？如果是，请查看此项

public IActionResult Edit(int? customer_id)
        {
        
        if (customer_id == null)
        {
            return NotFound();
        }

        Register Rg = new Register();

        Rg = RgEdit.GetRegisterByID(customer_id);

        if (Rg == null)
        {
            return NotFound();
        }
        return View(Rg);
    }


    [HttpPost]       
    public IActionResult Edit(int? customer_id , [Bind] Register Reg)
    {
        if(customer_id == null)
        {
            return NotFound();
        }

        if(ModelState.IsValid)
        {
            RgEdit.GetRegister(Reg);
            return RedirectToAction("reglis");
        }
        
        return View();
    }
