C# Deseralize - XML 文档中存在错误 (0， 0)

本文关键字：错误 存在 Deseralize XML 文档 | 更新日期: 2023-09-27 18:31:18

我正在尝试对 XDocumnet 进行解冻，但收到错误："XML Documnet（0， 0） 中存在错误。

.XML：

<Machine>
  <Asset>
    <Product>COMPELLENT SC8000,1st,2nd,UPG</Product>

      </Warranty>
    </Warranties>
  </Asset>
</Machine>

类：

  public class Service
    {
        [XmlElement("ServiceDescription")]
        public string ServiceDescription { get; set; }
        [XmlElement("Provider")]
        public string Provider { get; set; }
        [XmlElement("StartDate")]
        public string StartDate { get; set; }
        [XmlElement("EndDate")]
        public string EndDate { get; set; }
    }
    [XmlType("Warranty")]
    public class Warranty
    {        
        [XmlElement("Service")]
        public Service objWarranty = new Service();
        [XmlAttribute("Services")]
        public string Services {get; set;}
    }
    public class Asset
    {
        [XmlElement("Product")]
        public string Product { get; set; }
        [XmlElement("OrderNumber")]
        public string OrderNumber { get; set; }
        [XmlElement("ServiceTag")]
        public string ServiceTag { get; set; }
        [XmlElement("ShipDate")]
        public string ShipDate { get; set; }
        [XmlArray("Warranties")]
        public List<Warranty> objWarrantyList = new List<Warranty>();
    }

功能： -- 失败/错误

private static void XlDesc(XDocument doc)
        {
            XmlSerializer deserializer = new XmlSerializer(typeof(List<Asset>));
            List<Asset> assetlist = (List<Asset>)deserializer.Deserialize(doc.Root.CreateReader());
            foreach (var info in assetlist)
            {
                //ToDo
            }
        }

可能有更好的方法可以做到这一点。我对使用 Linq 和 xml 文件相当陌生。此 XML 是从现有 XML 文件创建的

前任：

 var groupByWarrany = xlWarranty.GroupBy(x => x.Service);
                var newDocument = new XDocument(new XElement("Machine", xlBaseInfo.Select(z =>
                    new XElement("Asset",
                        new XElement("Product", z.Product),
                        new XElement("OrderNumber", z.OrderNumber),
                        new XElement("ServiceTag", z.ServiceTag),
                        new XElement("ShipDate", z.ShipDate),
                            (new XElement("Warranties", groupByWarrany.Select(x =>
                                new XElement("Warranty", new XAttribute("Services", x.Key),
                                x.Select(y => new XElement("Service",   
                                new XElement("ServiceDescription", y.Service),
                                new XElement("Provider", y.Provider),
                                new XElement("StartDate", y.StartDate),
                                new XElement("EndDate", y.EndDate),
                                new XElement("Type", y.TypeOfWarranty)
                        )).FirstOrDefault()
                        ))))))));

我在想也许我可以跳过整个去膜化，并在创建新的 XDoc 时使用这些类。

C# Deseralize - XML 文档中存在错误 (0， 0)

因此，我们已经在类构造中发现了一些错误（请参阅注释）。在这种情况下，您有两个变体。

首先，逐步反序列化对象。创建服务 xml（手动或从示例中复制粘贴）并反序列化它，创建保修 xml 并反序列化它，创建无保修资产列表 xml 并反序列化它，最后创建具有保修的资产 xml 并反序列化它。在简单的类中更容易发现此类错误并增加难度。

第二种变体：使用 xsd 实用程序。你需要这样的
命令xsd.exe yourXml.xml/c
xsd.exe yourXml.xsd/c
（请参阅文档中的详细信息）。最后你会得到你的Xml.cs文件，其中包含所有必要的类。只需修复数组属性，它们有时会被处理得不对。

测试调用： 

XmlSerializer serializer = new XmlSerializer(typeof(Machine));
using (System.IO.FileStream stream = new System.IO.FileStream(@"C:'Users'Administrator'Desktop'test.xml", System.IO.FileMode.Open))
{
     Machine machine = (Machine)serializer.Deserialize(stream);
     // do stuff with machine
}

XML 文档的类

/// <remarks/>
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true)]
[System.Xml.Serialization.XmlRootAttribute(Namespace = "", IsNullable = false)]
public partial class Machine
{        /// <remarks/>
    public MachineAsset Asset { get; set; }
}
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true)]
public partial class MachineAsset
{
    public string Product { get; set; }
    public uint OrderNumber { get; set; }
    public uint ServiceTag { get; set; }
    public System.DateTime ShipDate { get; set; }
    [System.Xml.Serialization.XmlArrayItemAttribute("Warranty", IsNullable = false)]
    public MachineAssetWarranty[] Warranties { get; set; }
}
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true)]
public partial class MachineAssetWarranty
{
    public MachineAssetWarrantyService Service { get; set; }
    [System.Xml.Serialization.XmlAttributeAttribute()]
    public string Services { get; set; }
}
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true)]
public partial class MachineAssetWarrantyService
{
    public string ServiceDescription { get; set; }
    public string Provider { get; set; }
    public System.DateTime StartDate { get; set; }
    public System.DateTime EndDate { get; set; }
    public string Type { get; set; }
}
