试图将 XML 字符串解析为 c# 对象但没有成功

【问题标题】：Trying to parse XML string into c# object with no success试图将 XML 字符串解析为 c# 对象但没有成功
【发布时间】：2020-12-15 00:53:03
【问题描述】：

我正在尝试将一些 XML 字符串反序列化为一个对象。但总是出现下一个错误：

XML 文档 (1, 2) 中存在错误。 不是 预计。

我还尝试从 xml 中删除 xmlns:vehicle=\"http://www.travelport.com/schema/vehicle_v48_0\" 但后来我得到：'vehicle' 是一个未声明的前缀。第 1 行，位置 2。

对象是：

namespace VehicleMedia
{
    [XmlRoot(ElementName = "SupplierRate", Namespace = "http://www.travelport.com/schema/vehicle_v48_0")]
    public class SupplierRate
    {
        [XmlAttribute(AttributeName = "RateForPeriod")]
        public string RateForPeriod { get; set; }
        [XmlAttribute(AttributeName = "ExtraMileageCharge")]
        public string ExtraMileageCharge { get; set; }
    }

    [XmlRoot(ElementName = "VehicleRate", Namespace = "http://www.travelport.com/schema/vehicle_v48_0")]
    public class VehicleRate
    {
        [XmlElement(ElementName = "SupplierRate", Namespace = "http://www.travelport.com/schema/vehicle_v48_0")]
        public SupplierRate SupplierRate { get; set; }
        [XmlAttribute(AttributeName = "RatePeriod")]
        public string RatePeriod { get; set; }
    }

    [XmlRoot(ElementName = "Vehicle", Namespace = "http://www.travelport.com/schema/vehicle_v48_0")]
    public class Vehicle
    {
        [XmlElement(ElementName = "VehicleRate", Namespace = "http://www.travelport.com/schema/vehicle_v48_0")]
        public VehicleRate VehicleRate { get; set; }
        [XmlAttribute(AttributeName = "VendorCode")]
        public string VendorCode { get; set; }
        [XmlAttribute(AttributeName = "AirConditioning")]
        public string AirConditioning { get; set; }
        [XmlAttribute(AttributeName = "TransmissionType")]
        public string TransmissionType { get; set; }
        [XmlAttribute(AttributeName = "VehicleClass")]

        [XmlAttribute(AttributeName = "Category")]
        public string Category { get; set; }
        [XmlAttribute(AttributeName = "DoorCount")]
        public string DoorCount { get; set; }
        [XmlAttribute(AttributeName = "AcrissVehicleCode")]
        public string AcrissVehicleCode { get; set; }
    }

    [XmlRoot(ElementName = "MediaItem", Namespace = "http://www.travelport.com/schema/common_v48_0")]
    public class MediaItem
    {
        [XmlAttribute(AttributeName = "url")]
        public string Url { get; set; }
        [XmlAttribute(AttributeName = "sizeCode")]
        public string SizeCode { get; set; }
    }

    [XmlRoot(ElementName = "VehicleWithMediaItems", Namespace = "http://www.travelport.com/schema/vehicle_v48_0")]
    public class VehicleWithMediaItems
    {
        [XmlElement(ElementName = "Vehicle", Namespace = "http://www.travelport.com/schema/vehicle_v48_0")]
        public Vehicle Vehicle { get; set; }
        [XmlElement(ElementName = "MediaItem", Namespace = "http://www.travelport.com/schema/common_v48_0")]
        public MediaItem MediaItem { get; set; }
    }

    [XmlRoot(ElementName = "VehicleMediaLinksRsp", Namespace = "http://www.travelport.com/schema/vehicle_v48_0")]
    public class VehicleMediaLinksRsp
    {
        [XmlElement(ElementName = "VehicleWithMediaItems", Namespace = "http://www.travelport.com/schema/vehicle_v48_0")]
        public List<VehicleWithMediaItems> VehicleWithMediaItems { get; set; }
        [XmlAttribute(AttributeName = "TransactionId")]
        public string TransactionId { get; set; }
        [XmlAttribute(AttributeName = "ResponseTime")]
        public string ResponseTime { get; set; }
        [XmlAttribute(AttributeName = "vehicle", Namespace = "http://www.w3.org/2000/xmlns/")]
        public string Vehicle { get; set; }
        [XmlAttribute(AttributeName = "common_v48_0", Namespace = "http://www.w3.org/2000/xmlns/")]
        public string Common_v48_0 { get; set; }
    }

}

例如xml字符串是：

<vehicle:VehicleMediaLinksRsp xmlns:vehicle="http://www.travelport.com/schema/vehicle_v48_0" xmlns:common_v48_0="http://www.travelport.com/schema/common_v48_0" TransactionId="29EAAF810A07571D5ADA0638F657E2D2" ResponseTime="173">

那么为什么我会收到这个错误？ 谢谢。

【问题讨论】：

  • 欢迎来到 Stack Overflow。如果您可以为此提供一个minimal reproducible example，这将非常有帮助，它有一个格式良好但短 XML 文档，而不是一个单独一行的巨型文档。我怀疑只有一个带有一个子元素的根元素，以及要匹配的类，就足以证明这个问题。
  • 请注意格式。解释出了什么问题的错误被破坏了，XML 文本是一个非常长且不可读的行。您只需要第一个 XML 元素即可重现此类错误，无需任何内容。
  • 你确定吗？错误消息不适合 XML。您能否显示您尝试反序列化 XML 的代码？
  • XmlSerializer serializer1 = new XmlSerializer(typeof(VehicleMedia.VehicleMediaLinksRsp));使用 (StringReader reader = new StringReader(xml)) { VehicleMedia.VehicleMediaLinksRsp Vmedia = (VehicleMedia.VehicleMediaLinksRsp)(serializer.Deserialize(reader)); }
  • 你知道你可以edit你的问题吗？最好向您的问题添加其他信息，而不是将其隐藏在评论中。
