使用asp.net MVC以编程方式重定向到404页 [英] Redirect to 404 page programmatically using asp.net MVC

问题描述

我已经创建了一个Asp.net MVC应用程序.现在需要404处理.

I have created a Asp.net MVC application. Now required 404 handling.

已更新global.asax并根据状态代码显示404页面.还在web.config中添加了customErrors属性.工作正常.

Have updated global.asax and display 404 page based on status code. Also added customErrors property in web.config. Its working fine.

现在，如果有任何不符合我们要求的内容，我想以编程方式重定向到404.

Now I would like to redirect to 404 programmatically when any thing not match with our requirement.

即

if(!valid) 
{
    return RedirectToAction("Index", "Page404");
}

工作正常，但有2种状态，其中一种是301&然后是404.那么我该如何预防301?我只需要404.

It's working fine but there are 2 status one is 301 & then 404. So how can I prevent 301? I just need 404.

我该如何实现?

推荐答案

在您的web.config中，添加:

<customErrors mode="On" >
       <error statusCode="404" redirect="/404.shtml" />
</customErrors>

当找不到请求的资源时，它将在404.shtml页面上重定向.

This will redirect on 404.shtml page when requested resource is not found.

注意:对于这种情况，无需以编程方式重定向用户.

Note: No need to programmatically redirect users for such situation.

我从字面上建议:

if (Context.Response.StatusCode == 404) {
  // handle this
}
