Question

我是Asp.net MVC的新手。我有一个管理用户的应用程序。我的问题是，当我点击用户行的删除链接时，删除方法会在调用渲染删除方法后自动调用[AcceptVerbs（HttpVerbs.Post）]注释。因此，在我点击删除确认按钮之前删除了具有id的用户，之后发生了错误。

以前一切都很好。所以，我不知道为什么会这样。

我的代码：

        // GET: /User/Delete/5
        [Authorize]
        public ActionResult Delete(int id)
        {
            return View(GetByUserId(id));
        }


        // POST: /User/Delete/5
        [Authorize]
        [AcceptVerbs(HttpVerbs.Post)]
        public ActionResult Delete(Users user)
        {
           //some process
        }

第二个方法在调用第一个方法后自动调用。

观点：

<h2>Delete</h2>
<p class="error"><%= Html.Encode(ViewData["messages"]) %></p>
<h3>Are you sure you want to delete this?</h3>
<fieldset>
    <legend>Fields</legend>

    <div class="display-label">UserId</div>
    <div class="display-field"><%= Html.Encode(Model.UserId) %></div>

    <div class="display-label">UserName</div>
    <div class="display-field"><%= Html.Encode(Model.UserName) %></div>

    <div class="display-label">FullName</div>
    <div class="display-field"><%= Html.Encode(Model.FullName) %></div>

    <div class="display-label">Email</div>
    <div class="display-field"><%= Html.Encode(Model.Email) %></div>

    <div class="display-label">DayOfBirth</div>
    <div class="display-field"><%= Html.Encode(String.Format("{0:MM/dd/yyyy}", Model.DayOfBirth))%></div>

    <div class="display-label">Phone</div>
    <div class="display-field"><%= Html.Encode(Model.Phone) %></div>

    <div class="display-label">Active</div>
    <div class="display-field"><%= Html.Encode(Model.Active) %></div>

</fieldset>
<% using (Html.BeginForm()) { %>
    <p>
        <input type="submit" value="Delete" /> |
        <%= Html.ActionLink("Back to List", "Index") %>
    </p>
<% } %>

请在下面找到您的修改代码。

public class HomeController : Controller
{
    public ActionResult Index()
    {
        ViewBag.Message = "Welcome to ASP.NET MVC!";

        return View();
    }

    public ActionResult About()
    {
        return View();
    }

    public ActionResult Delete()
    {
        return View();
    }

    [AcceptVerbs(HttpVerbs.Post)]
    public ActionResult Delete(RegisterModel ob)
    {
        return RedirectToAction("Index");
    }
}

Index.cshtml

 @{
        ViewBag.Title = "Home Page";
    }
    <h2>@ViewBag.Message</h2>
    <h1>
        @Convert.ToString(ViewBag.Delete)
    </h1>
    <p>

        <br />
        @Html.ActionLink("Delete record", "Delete");
        <br />
        <br />
    </p>

delete.cshtml

@model MvcApplication1.Models.RegisterModel
@{
    ViewBag.Title = "Delete";
}
<h2>
    Delete</h2>
<div>
    Are you sure you want to delete this?</div>
@using (Html.BeginForm())
{
    <p>
        <input type="submit" value="Delete" />
        |
    </p>
}

以上代码与您的代码相同，并且工作正常。请看看。
