C# - XmlSerializer 只获取第一个 XML 元素

如何解决C# - XmlSerializer 只获取第一个 XML 元素

我需要序列化一个 XML 字符串并将其绑定到类。问题是，XmlSerializer 只获取我的 XML 字符串的第一个元素。

var xml = @"<cars>
                <car>
                    <make>Ford</make>
                    <model>Mustang</model>
                    <color>Red</color>
                </car>
                <car>
                    <make>Infiniti</make>
                    <model>G35</model>
                    <color>Red</color>
                </car>
            </cars>";

using (var reader = new StringReader(xml))
{
    var deserializer = new XmlSerializer(typeof(cars),new XmlRootAttribute("cars"));

    var r = (cars)deserializer.Deserialize(reader);
}

这是我要绑定到的类：

using System.Collections.Generic;

[System.SerializableAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true)]
[System.Xml.Serialization.XmlRootAttribute(Namespace = "",IsNullable = false)]
public partial class cars
{
    public carsCar car { get; set; }
}

[System.SerializableAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true)]
public partial class carsCar
{
    public object make { get; set; }
    public object model { get; set; }
    public object color { get; set; }
}

我试着改变这个

public carsCar car { get; set; }

为此：

public List<carsCar> car { get; set; }

但是我的 List<carsCar> 是空的。

解决方法

如果您将 xml 复制到剪贴板，然后在 Visual Studio 中转到“编辑”、“选择性粘贴”、“将 XML 粘贴为类”，它将生成正确的类结构。您可以调整这些类以获得所需的名称和数据类型。然后您的代码将起作用，r.car 将是一个汽车数组。
