如何在C#中以XML格式读取web.config部分? [英] How to read web.config section as XML in C#?

问题描述

以下是复制的示例:

如何读取自定义配置c#

我想从app.config中阅读以下自定义部分:

I want to read following custom section from app.config:

<StartupFolders>    
   <Folders name="a">
      <add folderType="Inst" path="c:\foo" />
      <add folderType="Prof" path="C:\foo1" />      
   </Folders>
   <Folders name="b">
      <add folderType="Inst" path="c:\foo" />
      <add folderType="Prof" path="C:\foo1" />      
   </Folders> 
</StartupFolders>

这也是我的情况.但是，我不想创建用于处理值的自定义类，在web.config中定义此类，然后最终使用它.它很重，可以满足我的需求.

And this is my case too. However, I don't want to create custom class for handling values, defining this class in web.config, and then finally using it. It is heavy-weight for my needs.

相反，我想做一些非常简单的事情-以XML格式检索节.然后，我可以使用常规的Linq.Xml对其进行解析.这样，我不需要为每个部分创建新的类，也不需要声明它们.就我的目的而言，一方面就足够了，而另一方面却极少(我做了一次，嵌套部分的键值映射器). IE.完美.

Instead I would like to do something very simple -- retrieve a section as XML. Then I could use regular Linq.Xml to parse it. This way, I don't need to create new classes per each section, I don't need to declare them. For my purpose it is sufficient on one hand, and minimal at the other (I do it once, key-value mapper for nested sections). I.e. perfect.

唯一缺少的部分是(我的问题)-如何将web.config部分作为XML获取? 请注意以下部分:

The only missing piece is (my question) -- how to get a web.config section as XML? Note about the section:

• 无法对其进行编码，因为必须手动对其进行编辑
• 由于相同的原因而无法序列化

因此，我不是要寻找一种解决方法来压缩整个部分作为appSettings中的值，而是要寻找一种方法来获取适当的XML段落.

So I am not looking for a workaround how to squeeze entire section as value in appSettings, but I am really looking for a method to get proper section as XML.

我想从ConfigManager(！)中获取它，因为这样一来，我不必处理要读取哪个web.config的问题，依此类推.比手动模仿web.config优先级的机会少.

I would like to get it from ConfigManager (!), because this way I don't have to deal with resolving which web.config should I read, etc. I.e. less chance to make mistake than mimicing web.config precedence manually.

请原谅我提醒您，但请避免使用答案"，您不应这样做，请在每个部分中使用自定义类，以此类推.我已经考虑过并选择反对.

推荐答案

我认为您必须手动执行并将Web配置加载到内存中.

I think you either have to do it manually and load the Web config into memory:

XmlDocument doc = new XmlDocument();
doc.Load(Server.MapPath("~/Web.config")); 

否则，您将需要创建要避免的自定义配置部分.

Or you will need to create the custom configuration sections you want to avoid.
