在App.Config中使用哪种编码? [英] Which encoding to use in App.Config?

问题描述

由于值中的& ，以下 config 文件导致错误:

Following config file causes error because of & in 'url' value:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <appSettings>
    <add key ="url" value ="http://www.example.com/?user=admin&password=1234"/>
  </appSettings>
</configuration>

问题是 config 文件中的键/值使用哪种编码?(即网址编码...)

The question is which encoding to use for key/value in a config file ? (i.e Url Encoding ...)

推荐答案

这是一个XML文件.因此，您必须XML保留所有保留字符:

This is an XML file. As such, you must XML-escape all reserved characters:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <appSettings>
    <add key ="url" value ="http://www.example.com/?user=admin&amp;password=1234"/>
  </appSettings>
</configuration>

通过编程，您可以使用 System.Web.HttpUtility.HtmlEncode 方法执行这种转义.是的，它的名字暗示了HTML特定的编码，但是以我的经验，这等同于XML的转义.

Programmatically you can perform this type of escaping using the System.Web.HttpUtility.HtmlEncode method. Yes, its name suggests HTML specific encoding, but in my experience this is equivalent to XML escaping.
