剛開始做ASP.NET應用程式的時候，自己一臉蒙B，具體的程式流程都不懂，所以自己打算寫一個最簡單的專案來看看ASP.NET MVC專案的具體流程。

若有寫得不好的，還望指出.

目錄結構如下圖所示：

在企業中開發的時候需要自建Area(領域),所以我把最初專案帶有的MVC資料夾我都刪除了。

Controllers（控制層） UserController.cs程式碼:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using WebApplication4.Areas.LZX.Models;
namespace WebApplication4.Areas.LZX.Controllers
{
    public class UserController : Controller
    {
        //
        // GET: /LZX/User/
        public ActionResult Index()
        {
            return View();
        }
        //操作名（方法名）必須與Views/User 下的cshtml檔案的名字一致,當return View(),就會跳轉到相對應的檢視
        public ActionResult LoginSuccess()
        {
            return View();
        }
       [HttpPost]
        public ActionResult Login(String UserName, String Password)
        {

            User user = new User();
            user.UserName = UserName;
            user.Password = Password;
         //可以寫具體的邏輯程式碼，比如登入驗證....
            return Json(user);
        }
	}
}
 
//可以寫具體的邏輯程式碼，比如登入驗證....
            return Json(user);
        }
	}
}

Models(模型層) User.cs程式碼：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace WebApplication4.Areas.LZX.Models
{
    public class User
    {
        public String UserName { get; set; }
        public String Password { get; set; }
    }
}
 

Views(檢視層) User/Index.cshtml程式碼:

@{
    ViewBag.Title = "Index";
}
<script src="https://apps.bdimg.com/libs/jquery/2.1.4/jquery.min.js"></script>
<h2>登入介面：</h2>
<form method="post">
    帳號：<input type="text" id="username" name="username" /><br /><br />
    密碼：<input type="password" id="password" name="password" /><br /><br />
    &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;  &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
    <input type="button" id="submit" value="登入" /><br />
</form>
<script>
    $(function () {
        $("#submit").click(function () {
   
            var UserName = $("#username").val();
            var Password = $("#password").val();
            $.ajax({
                type: "post",
                url:"/LZX/User/Login",
                data: { UserName: UserName, Password: Password },
                dataType:"json",
                async:false,
                success:function(data){
                alert(data.UserName);
                window.location.href = "/LZX/User/LoginSuccess?username="+data.UserName;              
                }
            });
        });
    });
</script>
 

Views(檢視層) User/LoginSuccess.cshtml程式碼:

@{
    ViewBag.Title = "LoginSuccess";
}

<h2>@Request["username"] LoginSuccess 登入成功。。。。</h2>

執行結果:
