将嵌套的XML元素反序列化为C＃中的类 [英] Deserialize nested XML element into class in C#

问题描述

我具有以下XML结构（为简便起见进行了编辑），我无法控制。

I have the following XML structure (edited for brevity) which I have no control over.

<GetVehicles>
    <ApplicationArea>
        <Sender>
            <Blah></Blah>
        </Sender>
    </ApplicationArea>
    <DataArea>
        <Error>
            <Blah></Blah>
        </Error>
        <Vehicles>
            <Vehicle>
                <Colour>Blue</Colour>
                <NumOfDoors>3</NumOfDoors>
                <BodyStyle>Hatchback</BodyStyle>
            <Vehicle>
        </Vehicles>
    </DataArea>
</GetVehicles>

我有以下课程：

[XmlRoot("GetVehicles"), XmlType("Vehicle")]
public class Vehicle
{
    public string Colour { get; set; }
    public string NumOfDoors { get; set; }
    public string BodyStyle { get; set; }
}

我希望能够将XML反序列化为一个单独的实例车辆类别。 XML在99％的时间中仅应返回一个 Vehicle元素。如果它在'Vehicles'元素中包含多个'Vehicle'元素，我还没有处理。

I want to be able to deserialize the XML into a single instance of this Vehicle class. 99% of the time, the XML should only return a single 'Vehicle' element. I'm not yet dealing with it yet if it contains multiple 'Vehicle' elements inside the 'Vehicles' element.

不幸的是，当前未映射XML数据。对我的班级财产；

Unfortunately, the XML data isn't currently being mapped to my class properties; they are being left blank upon calling my Deserialize method.

为了完整起见，这是我的Deserialize方法：

For completeness, here is my Deserialize method:

private static T Deserialize<T>(string data) where T : class, new()
{
    if (string.IsNullOrEmpty(data))
        return null;

    var ser = new XmlSerializer(typeof(T));

    using (var sr = new StringReader(data))
    {
        return (T)ser.Deserialize(sr);
    }
}

我不在乎其他父元素例如 ApplicationArea， Error等。我仅对提取 Vehicle元素中的数据很感兴趣。如何仅从XML反序列化数据？

I don't care about the other more parent elements such as 'ApplicationArea', 'Error' etc. I am only interesting in extracting the data within the 'Vehicle' element. How do I get it to only deserialize this data from the XML?

推荐答案

我不知道您的完整上下文问题，因此此解决方案可能不适合您的域。但是一种解决方案是将模型定义为：

I'm not aware of the full context of your problem, so this solution might not fit into your domain. But one solution is to define your model as:

[XmlRoot("Vehicle")] //<-- optional
public class Vehicle
{
    public string Colour { get; set; }
    public string NumOfDoors { get; set; }
    public string BodyStyle { get; set; }
}

并将特定节点传递到 Deserialize 方法：

and pass specific node into Deserialize method using LINQ to XML:

var vehicle = XDocument.Parse(xml)
                       .Descendants("Vehicle")
                       .First();

Vehicle v = Deserialize<Vehicle>(vehicle.ToString());


//display contents of v 
Console.WriteLine(v.BodyStyle);   //prints Hatchback
Console.WriteLine(v.Colour);      //prints Blue
Console.WriteLine(v.NumOfDoors);  //prints 3
