C# 需要帮助反序列化XML数据吗

我正在尝试使用C对下面的XML进行反序列化#

---

在运行测试用例调试模式后，XmlData4具有null，而不具有XML数据。请帮助我如何修改此代码以使其正常工作。

DataContract

和

DataMember

是

DataContractSerializer

的属性，因此您应该替换序列化器或使用

XmlSerializer

的属性（

XmlRoot，XmlElement

等）

更改反序列化类：

using System;
using System.Xml.Serialization;
using System.Collections.Generic;
namespace ConsoleApp4
{
    [XmlRoot(ElementName = "Sample")]
    public class Sample
    {
        [XmlElement(ElementName = "AccountId")]
        public string AccountId { get; set; }
        [XmlElement(ElementName = "AccountNumber")]
        public string AccountNumber { get; set; }
    }

    [XmlRoot(ElementName = "Samples")]
    public class Samples
    {
        [XmlElement(ElementName = "Sample")]
        public List<Sample> Sample { get; set; }
    }

    [XmlRoot(ElementName = "Invoice")]
    public class Invoice
    {
        [XmlElement(ElementName = "Samples")]
        public Samples Samples { get; set; }
    }
}

private static Invoice LoadInvoice(string fileName)
{
    var serializer = new XmlSerializer(typeof(Invoice));

    if (!File.Exists(fileName))
    {
        return null;
    }
    using (var fs = new FileStream(fileName, FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
    {
        return (Invoice)serializer.Deserialize(fs);
    }
}

结果：

using System;
using System.Xml.Serialization;
using System.Collections.Generic;
namespace ConsoleApp4
{
    [XmlRoot(ElementName = "Sample")]
    public class Sample
    {
        [XmlElement(ElementName = "AccountId")]
        public string AccountId { get; set; }
        [XmlElement(ElementName = "AccountNumber")]
        public string AccountNumber { get; set; }
    }

    [XmlRoot(ElementName = "Samples")]
    public class Samples
    {
        [XmlElement(ElementName = "Sample")]
        public List<Sample> Sample { get; set; }
    }

    [XmlRoot(ElementName = "Invoice")]
    public class Invoice
    {
        [XmlElement(ElementName = "Samples")]
        public Samples Samples { get; set; }
    }
}

private static Invoice LoadInvoice(string fileName)
{
    var serializer = new XmlSerializer(typeof(Invoice));

    if (!File.Exists(fileName))
    {
        return null;
    }
    using (var fs = new FileStream(fileName, FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
    {
        return (Invoice)serializer.Deserialize(fs);
    }
}

谢谢你的回答！！

private static Invoice LoadInvoice(string fileName)
{
    var serializer = new XmlSerializer(typeof(Invoice));

    if (!File.Exists(fileName))
    {
        return null;
    }
    using (var fs = new FileStream(fileName, FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
    {
        return (Invoice)serializer.Deserialize(fs);
    }
}
