Question

我有一个相当简单的项目是使用带有asp mvc 4和实体框架的ninject。我添加了一个编辑并根据视图创建了ActionResult，没有任何问题。但是删除ActionResult无效。

视图是基于实体的IEnumrable，具有简单的ActionLink

@Html.ActionLink("Delete", "Delete_Client", new { item.ClientId })

控制器也非常简单。

[HttpPost]
    public ActionResult Delete_Client(int id)
    {
        Client deleteClient = repository.DeleteClient(id);

        if (deleteClient != null)
        {
            TempData["message"] = string.Format("{0} was deleted.", deleteClient.Name);
        }

        return RedirectToAction("Admin_Client_List");
    }

这通过Iinterface

与模型交互

 Client DeleteClient(int id);

并在实体框架中

 public Client DeleteClient(int id)
    {
        Client dbEntry = context.Clients.Find(id);
        if (dbEntry != null)
        {
            context.Clients.Remove(dbEntry);
            context.SaveChanges();
        }
        return dbEntry;
    }

错误是

无法找到资源。

这非常令人困惑，因为我觉得我不理解框架的一个非常基本的原则。据我所知，这意味着客户端控制器没有相应的ActionResult。但是还有。本教程正在进行中，建议删除操作应幂等，因此只包含 [HttpPost] 。

Uri看起来像这样

/Client/Delete_Client?ClientId=12

我认为可能需要看起来像这样

/Client/Delete_Client/12

然而，这不起作用。

更新了Admin_Client_List.cshtml的请求

@model IEnumerable<Project.Domain.Entities.Client>

@{
    ViewBag.Title = "Client List";
    ViewBag.Icon = "entypo-layout";
    ViewBag.ClientActive = "active";
    Layout = "~/Views/Shared/_AdminLayout.cshtml";
}

<a href="@Url.Action("Create_Client","Client")" class="btn btn-primary">Create a new Client</a>
<div class="row">
    @foreach (var item in Model)
    {
        <div class="col-sm-3">

            <div class="tile-progress tile-blue">

                <div class="tile-header">
                    <a href="@Url.Action("Client_Details", "Client", new { id =item.ClientId})">
                        <h3>@item.Name <i class="entypo-right-open-big"></i> <span class="badge badge-secondary pull-right">7</span></h3>
                    </a>
                </div>

                <div class="tile-progressbar">
                    <span data-fill="78%" style="width: 78%;"></span>
                </div>

                <div class="tile-footer">
                    <h4>
                        <span class="pct-counter">78</span>% increase
                    </h4>

                    <span>@item.Description</span>

                </div>

                <div class="tile-header">
                    <a href="@Url.Action("Edit_Client", "Client", new { id = item.ClientId})" type="button" class="btn btn-blue btn-icon icon-left">
                        <i class="entypo-pencil"></i> Edit
                    </a>

                    @*<a href="javascript:$('#modal-6').modal('show', {backdrop: 'statuc'});" class="btn btn-default">Show Me</a>*@

                    @Html.ActionLink("Delete", "Delete_Client", new { id = item.ClientId }) 

                    @*<a href="@Url.Action("Delete_Client", "Client", new { item.ClientId })" class="btn btn-red btn-icon pull-right">Delete <i class="entypo-cancel"></i></a>*@
                </div>
            </div>

        </div>
    }
</div>

Answer 1

使用以下代码：

@Html.ActionLink("Delete", "Delete_Client", new { id = item.ClientId }) 


[HttpPost]
public ActionResult Delete_Client(int id)
{
    Client deleteClient = repository.DeleteClient(id);

    if (deleteClient != null)
    {
        TempData["message"] = string.Format("{0} was deleted.", deleteClient.Name);
    }

    return RedirectToAction("Admin_Client_List");
}

Answer 2

尝试

@Html.ActionLink("Delete", "Delete_Client", null, new { id = item.ClientId })

你必须删除[HttpPost]，这是一个GET请求

Answer 3

更改您的代码

@Html.ActionLink("Delete", "Delete_Client", new { item.ClientId })

到

@Html.ActionLink("Delete", "Delete_Client", new { id = item.ClientId })

[HttpPost]上的RedirectToAction返回“找不到资源”错误
