查询字符串参数没有值 [英] Query string parameters with no values

问题描述

我想建立一个具有两种行为的页面。我被URL他们分隔条件：一是行为是通过访问/有些控制器/一些行动，另一种是通过 /有些控制器/一些行动？定制。

I am trying to set up a page that has two behaviors. I'm seperating them by URL: One behavior is accessed via /some-controller/some-action, the other is via /some-controller/some-action?customize.

它看起来并不像的Request.QueryString对象包含什么，不过，当我访问了第二个URL ......我的意思是，领取钥匙中有一个元素，但它的空，而不是自定义。任何人有这个或任何想法如何启用此功能。我想，以避免手动不惜一切代价解析查询字符串。）

It doesn't look like the Request.QueryString object contains anything, though, when I visit the second URL...I mean, the keys collection has one element in it, but it's null, not 'customize'. Anyone have any ideas about this or how to enable this. I'd like to avoid manually parsing the query string at all costs :).

推荐答案

ASP.NET不支持确定的查询字符串参数presence没有值，因为的Request.QueryString [自定义] 和的Request.QueryString [富] 都是空。你要么必须自己解析它，或如指定值？自定义= 1

ASP.NET does not support determining the presence of query string parameters without values since Request.QueryString["customize"] and Request.QueryString["foo"] are both null. You'll either have to parse it yourself or specify a value e.g. ?customize=1
