How can I add an ampersand for a value in a ASP.net/C# app config file value
提问by Rob Segal
I've got a C# program with values in a config file. What I want is to store ampersands for an url value like...
我有一个 C# 程序，在配置文件中有值。我想要的是为一个 url 值存储 & 符号，例如...
<appSettings>
<add key="myurl" value="http://www.myurl.com?&cid=&sid="/>
</appSettings>
But I get errors building my site. The ampersand is not allowed. I've tried various forms of escaping the ampersands to no avail. Anyone know of the correct form to do this? All suggestions are welcome.
但是我在构建我的网站时出错。不允许使用与符号。我已经尝试了各种形式的转义符无济于事。任何人都知道正确的形式来做到这一点？欢迎提出所有建议。

Use "&" instead of "&".
使用“ &”代替“&”。

I think you should be able to use the HTML escape character (&). They can be found at http://www.theukwebdesigncompany.com/articles/entity-escape-characters.php

Although the accepted answer here is technically correct, there seems to be some confusion amongst users based on the comments. When working with a ViewBag in a .cshtml file, you must use @Html.Rawotherwise your data, after being unescaped by the ConfigurationManager, will become re-escaped once again. Use Html.Raw()to prevent this from occurring.
尽管此处接受的答案在技术上是正确的，但根据评论，用户之间似乎有些混淆。在 .cshtml 文件中使用 ViewBag 时，您必须使用@Html.Raw否则您的数据，在被 ConfigurationManager取消转义后，将再次重新转义。使用Html.Raw()，以防止这种情况发生。
