Question

我是MVC的新手。我正在尝试创建一个简单的用户注册过程

当我尝试运行应用程序时，我遇到错误HTTP 404。无法找到该资源。请求的URL：/Mvc_Web_Project/Views/CreateNewUser/AddUser.cshtml

我在网上找到的解决方案没有解决问题

RouteConfig.cs

public static void RegisterRoutes(RouteCollection routes)
    {

      routes.MapRoute(
      name: "Default",
      url: "{controller}/{action}/{id}",
      defaults: new { controller = "CreateNewUser", action = "AddUser", id = UrlParameter.Optional }
        );
    }

Controller.cs

using System.Web.Mvc;
using System.Data.SqlClient;
using System.Configuration;
using System.Data;
using Mvc_Web_Project.Models;

 namespace Mvc_Web_Project.Controllers
 {
   public class CreateNewUserController : Controller
   {
    private SqlConnection con;
    private void connection()
    {
        string constr = ConfigurationManager.ConnectionStrings["Molecular"].ToString();
        con = new SqlConnection(constr);
    }

    // GET: CreateNewUser
    public ActionResult AddUser(AddUserModel CreateNewUser)
    {
        //To Prevent firing validation error on first page Load  

        if (ModelState.IsValid)
        {
            connection();
            SqlCommand com = new SqlCommand("AddUser", con);
            com.CommandType = CommandType.StoredProcedure;
            com.Parameters.AddWithValue("@Email", CreateNewUser.Email);
            com.Parameters.AddWithValue("@Password", CreateNewUser.Password);
            com.Parameters.AddWithValue("@Type", CreateNewUser.Type);               
            con.Open();
            int i = com.ExecuteNonQuery();
            con.Close();
            if (i >= 1)
            {
                ViewBag.Message = "New User Added Successfully";
            }
        }
        ModelState.Clear();
        return View();
    }
   }
  }

CSHTML

   @model Mvc_Web_Project.Models.AddUserModel
@{
ViewBag.Title = "Create New User";
Layout = "~/Views/Shared/_Layout.cshtml";
  }

<h2>AddUser</h2>

  @using (Html.BeginForm())
  {
    @Html.ValidationSummary(true)

<fieldset>
    <legend> AddUserModel</legend>


    <div class="editor-label">
        @Html.LabelFor(model => model.Email)
    </div>
    <div class="editor-field">
        @Html.EditorFor(model => model.Email)
        @Html.ValidationMessageFor(model => model.Email)
    </div>

    <div class="editor-label">
        @Html.LabelFor(model => model.Password)
    </div>
    <div class="editor-field">
        @Html.EditorFor(model => model.Password)
        @Html.ValidationMessageFor(model => model.Password)
    </div>


    <div class="editor-label">
        @Html.LabelFor(model => model.Type)
    </div>
    <div class="editor-field">
        @Html.EditorFor(model => model.Type)
        @Html.ValidationMessageFor(model => model.Type)
    </div>

    <p>
        <input type="submit" value="Save details" />
    </p>

</fieldset>
 }

您的ASP.NET Web应用程序的开始操作似乎设置为当前页面，在您的情况下，这会导致Visual Studio启动浏览器导航到/Mvc_Web_Project/Views/CreateNewUser/AddUser.cshtml路径。

要更改此设置，一个选项是转到“项目属性”窗口并从当前页面更改为特定页面并使用空值，这将导致浏览器始终导航到应用程序的根目录：

以下是docs的链接，可以更详细地解释这些选项。
