I am using XDocument to switch a value in an xml document. In the new value I need to use the character '&' (ampersand) but after XDocument.save() the xml has & instead!
我正在使用XDocument切换xml文档中的值。在新的值中，我需要使用字符'&'(&')，但是在XDocument.save()之后，xml有&相反!
I tried using encoding and stuff… nothing worked
我试着用编码之类的东西…什么都没用

XDocument is doing exactly what it's supposed to do.
XDocument正在做它应该做的事。
& is invalid XML. (it's an unfinished character/entity reference)
&是无效的XML。(这是一个未完成的字符/实体引用)

& means "Start of an entity" in XML so if you want to include an & as data you must express it as an entity — & (or use it in a CDATA block).
&在XML中表示“开始一个实体”，因此如果您想包含&作为数据，您必须将它表示为一个实体& & &;(或者在CDATA块中使用)。
What you describe is normal behaviour and the XML would break otherwise.
您所描述的是正常的行为，否则XML将会崩溃。

There are two options. Either to ensure proper XML encoding/decoding of all your content in the XML document. Remember that HTML and XML encoding/decoding is slightly different.
有两个选项。要么确保正确的XML编码/解码XML文档中的所有内容。请记住，HTML和XML编码/解码略有不同。
Option two is to use base64 encoding on whatever content in the xml that might contain invalid elements.
选项二是对xml中可能包含无效元素的任何内容使用base64编码。

Is your output file app.config supposed to be an XML file?
您的输出文件app.config是否应该是一个XML文件?
If it is, then the & must be escaped as &.
如果是，则&必须以& * *形式转义。
If it isn't, then you should be using the text output method instead of the xml output method: use <xsl:output method='text'/>.
如果不是，那么应该使用文本输出方法而不是xml输出方法:使用 。
PS: this question appears to be a duplicate of How can I add an ampersand for a value in a ASP.net/C# app config file value
PS:这个问题似乎是如何在一个asp.net/c# app配置文件值中添加一个&号作为一个值的重复问题
