Question

我正在尝试将字符串反序列化为对象。 xml节点是否像语法一样，但不是xml（因为没有根节点或命名空间）。这是我到目前为止，有这个错误：

<delivery xmlns=''>. was not expected

反序列化代码：

var number = 2;
var amount = 3;
var xmlCommand = $"<delivery number=\"{number}\" amount=\"{amount}\" />";
XmlSerializer serializer = new XmlSerializer(typeof(Delivery));
var rdr = new StringReader(xmlCommand);
Delivery delivery = (Delivery)serializer.Deserialize(rdr);

交付对象：

using System.Xml.Serialization;

namespace SOMWClient.Events
{
    public class Delivery
    {
        [XmlAttribute(AttributeName = "number")]
        public int Number { get; set; }

        [XmlAttribute(AttributeName = "amount")]
        public string Amount { get; set; }

        public Delivery()
        {

        }
    }
}

如何在反序列化时避免xmlns错误？

Answer 1

像这样自己添加root：

XmlRootAttribute root = new XmlRootAttribute();
root.ElementName = "delivery";
// root.Namespace = "http://www.whatever.com";
root.IsNullable = true;

// your code goes below

Answer 2

更改Delivery类并添加有关根元素的信息（XmlRoot属性）：

[System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true)]
[XmlRoot("delivery")]
public class Delivery
{
    [XmlAttribute(AttributeName = "number")]
    public int Number { get; set; }

    [XmlAttribute(AttributeName = "amount")]
    public string Amount { get; set; }

    public Delivery()
    { }
}

将字符串（xml节点，如语法）反序列化为c＃对象
