反序列化XML数组 [英] Deserialize an XML array
问题描述
我使用单个元素进行反序列化。但是当我有xml元素数组时，我的代码无效。
下面是我的代码
我尝试过：
I got deserializing working with single element. But when I have array of xml elements, my code is not working.
Below is my code
What I have tried:
<data>
<cars>
<body>
<color>blue<color>
<type>sedan</type>
</body>
<details>
<year>2016</year>
<make>Infiniti</make>
</details>
</cars>
<cars>
<body>
<color>white<color>
<type>SUV</type>
</body>
<details>
<year>2016</year>
<make>Lexus</make>
</details>
</cars>
</data>
Dto
Dto
[XmlRoot("cars")]
public class CarDetails
{
[XmlElement("body")]
public Body BodyList { get; set; }
[XmlElement("details")]
public DetailsList details { get; set; }
}
public class Body
{
public string Color { get; set; }
public string Type { get; set; }
}
public class DetailsList
{
public int Year { get; set; }
public string Make { get; set; }
}
以下是反序列化的代码：
Below is the code for deserializing:
CarDetails[] details;
XmlSerializer serializer = new XmlSerializer(typeof(CarDetails[]));
using (TextReader reader = new StringReader(output))
{
details = (CarDetails[])serializer.Deserialize(reader);
}
推荐答案
我认为你可以这样做，但你可能需要改变你的课程才能使这个工作，我刚刚使用了具有公共属性的普通类：
I think you can do it like this, but you might have to change your class for this to work, I just used a "normal" class with public properties:
string xml = File.ReadAllText(@"test.xml");
List<CarDetails> res = new List<CarDetails>();
var serializer = new XmlSerializer(res.GetType());
using (TextReader reader = new StringReader(xml))
{
res = (List<CarDetails>)serializer.Deserialize(reader);
}
首先，您遇到无效结束标记的问题 - 这里：
First, you have a problem with an invalid ending tag - here:
<color>blue<color>
应该是：
should be:
<color>blue</color>
与：
相同
same with:
<color>white<color>
应该是：
should be:
<color>white</color>
接下来，您需要为XML生成类。这里有两个选择：
选项1。（首选）
这是一个从XML生成类的有用工具： [ ^ ]
生成此：
Next, You need to generate classes for your XML. Here are two options:
Option 1. (Preferred)
Here is a useful tool to generate classes from XML: [^]
Generates this:
/*

http://www.apache.org/licenses/LICENSE-2.0
*/
using System;
using System.Xml.Serialization;
using System.Collections.Generic;
namespace Xml2CSharp
{
[XmlRoot(ElementName="body")]
public class Body {
[XmlElement(ElementName="color")]
public string Color { get; set; }
[XmlElement(ElementName="type")]
public string Type { get; set; }
}
[XmlRoot(ElementName="details")]
public class Details {
[XmlElement(ElementName="year")]
public string Year { get; set; }
[XmlElement(ElementName="make")]
public string Make { get; set; }
}
[XmlRoot(ElementName="cars")]
public class Cars {
[XmlElement(ElementName="body")]
public Body Body { get; set; }
[XmlElement(ElementName="details")]
public Details Details { get; set; }
}
[XmlRoot(ElementName="data")]
public class Data {
[XmlElement(ElementName="cars")]
public List<Cars> Cars { get; set; }
}
}
选项2。
此外，Visual Studio（在VS2017上测试）也可以从XML生成类：
1.将XML数据复制到剪贴板
2.在VS中，编辑>选择性粘贴> 将Xml粘贴为类
生成此：
Option 2.
Also, Visual Studio (tested on VS2017) can also generate classes from XML:
1. Copy XML data to the clipboard
2. In VS, Edit > Paste Special > "Paste Xml as classes"
Generates this:
/// <remarks/>
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true)]
[System.Xml.Serialization.XmlRootAttribute(Namespace = "", IsNullable = false)]
public partial class data
{
private dataCars[] carsField;
/// <remarks/>
[System.Xml.Serialization.XmlElementAttribute("cars")]
public dataCars[] cars
{
get
{
return this.carsField;
}
set
{
this.carsField = value;
}
}
}
/// <remarks/>
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true)]
public partial class dataCars
{
private dataCarsBody bodyField;
private dataCarsDetails detailsField;
/// <remarks/>
public dataCarsBody body
{
get
{
return this.bodyField;
}
set
{
this.bodyField = value;
}
}
/// <remarks/>
public dataCarsDetails details
{
get
{
return this.detailsField;
}
set
{
this.detailsField = value;
}
}
}
/// <remarks/>
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true)]
public partial class dataCarsBody
{
private string colorField;
private string typeField;
/// <remarks/>
public string color
{
get
{
return this.colorField;
}
set
{
this.colorField = value;
}
}
/// <remarks/>
public string type
{
get
{
return this.typeField;
}
set
{
this.typeField = value;
}
}
}
/// <remarks/>
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true)]
public partial class dataCarsDetails
{
private ushort yearField;
private string makeField;
/// <remarks/>
public ushort year
{
get
{
return this.yearField;
}
set
{
this.yearField = value;
}
}
/// <remarks/>
public string make
{
get
{
return this.makeField;
}
set
{
this.makeField = value;
}
}
}
因此，对于您的问题，选项1。用于收集汽车：
So for your question, Option 1. uses for the collection of cars:
[XmlElement(ElementName="cars")]
public List<Cars> Cars { get; set; }
和选项2。使用：
and Option 2. uses:
private dataCars[] carsField;
/// <remarks/>
[System.Xml.Serialization.XmlElementAttribute("cars")]
public dataCars[] cars
{
get
{
return this.carsField;
}
set
{
this.carsField = value;
}
}
可以简化为：
Which could be simplified as:
private dataCars[] carsField;
/// <remarks/>
[System.Xml.Serialization.XmlElement("cars")]
public dataCars[] cars
{
get => carsField;
set => carsField = value;
}
