替换查询字符串中的项目 [英] Replace item in querystring

问题描述

我有一个URL，它也可能包含查询字符串部分，查询字符串可能为空或包含多个项目.

I have a URL that also might have a query string part, the query string might be empty or have multiple items.

我想替换查询字符串中的一项，或者如果项不存在则添加它.

I want to replace one of the items in the query string or add it if the item doesn't already exists.

我有一个带有完整URL的URI对象.

I have an URI object with the complete URL.

我的第一个想法是使用正则表达式和一些字符串魔术，应该这样做.

My first idea was to use regex and some string magic, that should do it.

但是似乎有些不稳定，也许框架中有一些查询字符串生成器类?

But it seems a bit shaky, perhaps the framework has some query string builder class?

推荐答案

也许您可以使用System.UriBuilder类.它具有Query属性.

Maybe you could use the System.UriBuilder class. It has a Query property.
