如何获得MVC行动来回报404 [英] How to get MVC action to return 404

问题描述

我有取入用于检索某些数据的字符串的操作。如果返回在没有数据这个字符串的结果（也许是因为它已被删除），我想回到404，并显示一个错误页面。

I have an action that takes in a string that is used to retrieve some data. If this string results in no data being returned (maybe because it has been deleted), I want to return a 404 and display an error page.

我目前只使用返回显示特定于这个动作说，该项目未找到一个友好的错误消息的特殊视图。这工作得很好，但在理想情况下想回404状态code使搜索引擎知道这个内容不再存在，并且可以从搜索结果中删除。

I currently just use return a special view that display a friendly error message specific to this action saying that the item was not found. This works fine, but would ideally like to return a 404 status code so search engines know that this content no longer exists and can remove it from the search results.

什么是去最好的方法？

时的那样简单设置Response.Status code = 404？

Is it as simple as setting Response.StatusCode = 404?

推荐答案

有多种方法可以做到这一点，

There are multiple ways to do it,

1. 您是对普通的aspx code它可以在你指定的方式分配


2. 抛出新的HttpException（404，有些说明）;

1. You are right in common aspx code it can be assigned in your specified way
2. throw new HttpException(404, "Some description");
