Edit is not working or functioning in my ASP.NET MVC 5 project

Question

Basically I'm creating a simple register function and I'm stuck at edit.

This is my model:

public partial class User
{ 
    public int UserId { get; set; }

    [Required(ErrorMessage ="This field is required")]
    public string User_name { get; set; }

    [Required(ErrorMessage = "This field is required")]
    public string User_funame { get; set; }

    [Required(ErrorMessage = "This field is required")]
    [DataType(DataType.Password)]
    public string User_pass { get; set; }

    [DataType(DataType.Password)]
    [DisplayName("Confirm Password")]
    [Compare("User_pass")]
    public string confirmpass { get; set; }

    [Required(ErrorMessage = "This field is required")]
    public string User_no { get; set; }

    [Required(ErrorMessage = "This field is required")]
    public string User_age { get; set; }

    [Required(ErrorMessage = "This field is required")]
    public string User_email { get; set; }
}

And this is my controller for editing:

public class UserController:Controller
{
    public ActionResult TestingUserProfile()
    {
        int id = Convert.ToInt32(Session["userID"]);

        using (DBModels dc = new DBModels()) 
        {
            if (id == 0)
            {
                return RedirectToAction("Login");
            }

            return View(dc.Users.Find(id));
        }
    }

    public ActionResult Edit(int id)
    {
        using (DBModels db = new DBModels())
        {
            return View(db.Users.Where(x => x.UserId == id).FirstOrDefault());
        }
    }

    [HttpPost]
    public ActionResult Edit(int id, User user)
    {
        try
        {
            using (DBModels db = new DBModels())
            {
                db.Entry(user).State = EntityState.Modified;
                db.SaveChanges();
            }

            return RedirectToAction("TestingUserProfile");
        }
        catch
        {
            return View();
        }
    }
}

And this is my view. So instead of showing the whole list of users, it will only shows the current logged in user's details.

@model WebApplication1.Models.User

@{
  ViewBag.Title = "User Profile";
}

<h2>User Profile</h2>

 <div>

<hr />
<dl class="dl-horizontal">
    <dt>
        @Html.DisplayName("User name :")
    </dt>

    <dd>
        @Html.DisplayFor(model => model.User_name)
    </dd>
    <br />
    <dt>
        @Html.DisplayName("Full name :")
    </dt>

    <dd>
        @Html.DisplayFor(model => model.User_funame)
    </dd>
    <br />
    <dt>
        @Html.DisplayName("Password :")
    </dt>

    <dd>
        @Html.DisplayFor(model => model.User_pass)
    </dd>

    <br />

    <dt>
        @Html.DisplayName("Phone Number :")
    </dt>

    <dd>
        @Html.DisplayFor(model => model.User_no)
    </dd>
    <br />
    <dt>
        @Html.DisplayName("Age :")
    </dt>

    <dd>
        @Html.DisplayFor(model => model.User_age)
    </dd>
    <br />
    <dt>
        @Html.DisplayName("Email :")
    </dt>

    <dd>
        @Html.DisplayFor(model => model.User_email)
    </dd>
    <br />
      </dl>
  </div>
      <p>
           @Html.ActionLink("Edit", "EditUserProfile", new { id = Model.UserId }) |
           @Html.ActionLink("Back", "SelectCourse")
      </p>
   

And this is the view for editing.

          @model WebApplication1.Models.User

         @{
             ViewBag.Title = "EditUserProfile";
          }

              <h2>Edit User Profile</h2>

                @using (Html.BeginForm())
                  {
                    @Html.AntiForgeryToken()
 
        <div class="form-horizontal">
    
          <hr />
           @Html.ValidationSummary(true, "", new { @class = "text-danger" })
          @Html.HiddenFor(model => model.UserId)

         <div class="form-group">

    </div>

                db.SaveChanges();
            }

            return RedirectToAction("TestingUserProfile");

        catch

I Think that your View Edit action link should be like below

@Html.ActionLink("EditUserProfile","Edit", new { id = Model.UserId })

or

<a href="@Url.Action("Edit")/@Model.UserId" >EditUserProfile</a>
