Question

首先，对不起，我知道我的问题将是非常基本的，但我会非常感谢一些帮助，我承受着很大的压力，所以做出明智的评论和具有讽刺意味不会帮助

我有这个代码：至少我在尝试。我有这个xml文件，我需要在类中保存它的所有属性，这样我就可以随时复制它。

我不知道该怎么做。

public static void firstFileXml(string sXml1)
{
    var root = XElement.Load(@"sXml1");
    var controlElementsFirst = root.Descendants("books");
}

XML文件具有以下属性：label，text，label_w等。我需要一个能让我输入的函数或者一些东西：探索（xmlLocation）并完成其余的工作。因为我需要为几个xml文件执行此操作

我需要构建一个允许我阅读它的类。假设我有这个xml文件：

WAS

    <books>
        <book label='' page='' intro =''/>
        <book label='' page='' intro =''/>
        <book label='' page='' intro =''/>
    </books>

IS

<SHEET>
<books>
<book label='1' page='1' intro='1'/>
<book label='2' page='2' intro='2'/>
<book label='3' page='3' intro='3'/>
</books>
</SHEET>

等等。我首先要读取这个xml文件，然后将书籍属性存储在一个类中，这样我以后就可以将它用于数百本书

代码：

using System;
using System.Collections.Generic;
using System.IO;
using System.Xml.Serialization;

static class Program
{
    static void Main()
    {
        // get the xml as a string; note that we could also use
        // Deserialize(Stream) to process a FileStream, but this
        // works fine
        string xml = File.ReadAllText(@"C:\Users\books.xml");
        var ser = new XmlSerializer(typeof(BookRoot));
        var root = (BookRoot)ser.Deserialize(new StringReader(xml));
        foreach (var book in root.Books)
        {
            Console.WriteLine("label: " + book.Label);
            Console.WriteLine("page: " + book.Page);
            Console.WriteLine("intro: " + book.Intro);
            Console.ReadLine();
        }
    }
}
[XmlRoot("SHEET")]
public class BookRoot
{
    private readonly List<Book> books = new List<Book>();
    [XmlArray("books"), XmlArrayItem("book")]
    public List<Book> Books { get { return books; } }
}
public class Book
{
    [XmlAttribute("label")]
    public string Label { get; set; }
    [XmlAttribute("page")]
    public string Page { get; set; }
    [XmlAttribute("intro")]
    public string Intro { get; set; }
}

在命令行：

xsd yourfile.xml
xsd /c yourfile.xsd

这将使用xml作为模板创建C＃类（通过模式推理）;然后，您可以使用XmlSerializer的那些类，即

var ser = new XmlSerializer(typeof(YourRootType));
YourRootType root = (YourRootType)ser.Deserialize(source);
Console.WriteLine(root.Foo);
foreach(Bar bar in root.Bars) {
    Console.WriteLine(bar.Name);
    Console.WriteLine(bar.Id);
}

例如，使用：

<books>
<book label='' page='' intro=''/>
<book label='' page='' intro=''/>
<book label='' page='' intro=''/>
</books>

这会生成架构：

<?xml version="1.0" encoding="utf-8"?>
<xs:schema id="books" xmlns="" xmlns:xs="http://www.w3.org/2001/XMLSchema"
    xmlns:msdata="urn:schemas-microsoft-com:xml-msdata">
  <xs:element name="books" msdata:IsDataSet="true" msdata:Locale="en-US">
    <xs:complexType>
      <xs:choice minOccurs="0" maxOccurs="unbounded">
        <xs:element name="book">
          <xs:complexType>
            <xs:attribute name="label" type="xs:string" />
            <xs:attribute name="page" type="xs:string" />
            <xs:attribute name="intro" type="xs:string" />
          </xs:complexType>
        </xs:element>
      </xs:choice>
    </xs:complexType>
  </xs:element>
</xs:schema>

然后是C＃代码：

//     Runtime Version:4.0.30319.34014

        }
        set {
            this.itemsField = value;
        }
    }
}

    private string introField;

    /// <remarks/>
    [System.Xml.Serialization.XmlAttributeAttribute()]
    public string label {
        get {
            return this.labelField;
        }
        set {
            this.labelField = value;
        }
    }

    /// <remarks/>
    [System.Xml.Serialization.XmlAttributeAttribute()]
    public string page {
        get {
            return this.pageField;
        }
        set {
            this.pageField = value;
        }
    }

    /// <remarks/>
    [System.Xml.Serialization.XmlAttributeAttribute()]
    public string intro {
        get {
            return this.introField;
        }
        set {
            this.introField = value;
        }
    }
}

适用于XmlSerializer，可以正确反序列化您的数据，例如：

var ser = new XmlSerializer(typeof(books));
var root = (books)ser.Deserialize(new StringReader(xml));
foreach(var book in root.Items)
{
    Console.WriteLine("label: " + book.label);
    Console.WriteLine("page: " + book.page);
    Console.WriteLine("intro: " + book.intro);
}

请注意，您可以手动轻松完成：

[XmlRoot("books")]
public class BookRoot {
    private readonly List<Book> books = new List<Book>();
    [XmlElement("book")]
    public List<Book> Books { get { return books; } }
}
public class Book {
    [XmlAttribute("label")]
    public string Label {get;set;}
    [XmlAttribute("page")]
    public string Page {get;set;}
    [XmlAttribute("intro")]
    public string Intro {get;set;}
}

例如：

var ser = new XmlSerializer(typeof(BookRoot));
var root = (BookRoot)ser.Deserialize(new StringReader(xml));
foreach(var book in root.Books)
{
    Console.WriteLine("label: " + book.Label);
    Console.WriteLine("page: " + book.Page);
    Console.WriteLine("intro: " + book.Intro);
}

使用最新的编辑在XML中添加级别，属性需要稍微调整一下 - 更改根元素名称，并添加其他级别（books/book =＆gt; SHEET/books/book ）：

[XmlRoot("SHEET")]
public class BookRoot
{
    private readonly List<Book> books = new List<Book>();
    [XmlArray("books"), XmlArrayItem("book")]
    public List<Book> Books { get { return books; } }
}

从xml文件构建类
