无法读取xml节点

[英]Can't read xml nodes

I've the following XML saved into settings.config : 我将以下XML保存到settings.config

<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<Settings>
  <Type>15</Type>
  <Module>True</Module>
  <Capacity>10</Capacity>
</Settings>

I've created a class like this: 我创建了一个这样的类:

 public class Settings
 {
      public int Type { get; set; }
      public bool Module { get; set; }
      public int Capacity { get; set; }
 }

and this is my code that deserialize the XML : 这是我的反序列化XML代码:

XDocument doc = XDocument.Load("settings.config");
        var settings = doc.Root
                          .Elements("Settings")
                          .Select(x => new Settings
                          {
                              Type = (int)x.Attribute("Type"),
                              Module = (bool)x.Attribute("Module"),
                              Capacity = (int)x.Attribute("Capacity"),
                          })
                          .ToList();

The problem is that the settings variable return Count = 0 . 问题是settings变量返回Count = 0 What am I doing wrong? 我究竟做错了什么?

A few issues with your XML XML的一些问题

  1. <Settings> is your Root, it is not an element of your root. <Settings>是您的根,不是您根的元素。 If you want to have multiple <Settings> , then make a new root element, and put the <Settings> tags inside that. 如果要具有多个<Settings> ,则创建一个新的根元素,并将<Settings>标记放入其中。
  2. Type , Module , and Capacity are Elements, not Attributes TypeModuleCapacity是元素,而不是属性

If you only have 1 settings note, you can do something like the following: 如果只有1个设置注释,则可以执行以下操作:

var settignsNode = doc.Element("Settings");

var settings = new Settings()
{
    Type = (int)settignsNode.Element("Type"),
    // ...
};

Working example, but answer above is really explain what is going here 工作示例,但是上面的答案实际上是在解释这里的情况

XDocument doc = XDocument.Parse("<?xml version=\"1.0\" encoding=\"utf-8\" standalone=\"yes\"?><Settings><Type>15</Type><Module>True</Module><Capacity>10</Capacity></Settings>");
var settings = doc
                          .Elements("Settings")
                          .Select(x => new Settings
                          {
                              Type = (int.Parse(x.Elements("Type").First().Value)),
                              Module = bool.Parse(x.Elements("Module").First().Value),
                              Capacity = (int.Parse(x.Elements("Capacity").First().Value)),
                          })
                          .ToList();

Working code 工作代码

XDocument doc = XDocument.Parse("<Settings><Type>15</Type><Module>True</Module><Capacity>10</Capacity></Settings>");
var settings = doc
               .Elements("Settings")
               .Select(x => new Settings
               {
                   Type = (int)x.Element("Type"),
                   Module = (bool)x.Element("Module"),
                   Capacity = (int)x.Element("Capacity"),
                })
                .ToList();
