在C#中将XML反序列化为类obj

Question

这是我在200多个这样的条目的巨大XML文件中的条目之一.

<TradeFills>
 <TradeFill>
  <Broker>xxx</Broker>
  <CustomerAccount/>
  <qwFillTransID>xxxxxxxxxxxxxxxxxxx</qwFillTransID>
  <qwPrevTransID>xxx</qwPrevTransID>
  <qwGroupTransID>xxxxxxxxxxxxxxxxx</qwGroupTransID>
  <GroupTransID>xxxxxxxx</GroupTransID>
  <TransID>x</TransID>
  <Service>xxxxxxxxxxxxxxxx</Service>
  <Symbol>xx</Symbol>
  <Exchange>xxxxx</Exchange>
  <InstClass>xxxxxxxx</InstClass>
  <InstSubClass>xxxxxxx</InstSubClass>
  <ContractSymbol>xxxx</ContractSymbol>
  <ExpirationDate>xxxxxxxx</ExpirationDate>
  <Month>xx</Month>
  <Year>xxxx</Year>
  <Strike>xxx</Strike>
  <TradePCU>xxxx</TradePCU>
  <Buy>x</Buy>
  <Quantity>xx</Quantity>
  <Price>xxxxx</Price>
  <FillTime>xxxxxxxxxxxxxxx</FillTime>
  <PosUpdated>xxxxxxxxxxx</PosUpdated>
  <Description/>
 </TradeFill>
</TradeFills>

我试图将其反序列化为类对象,但每次都失败.

到目前为止这是我的代码:

using System;

使用System.Collections.Generic; 使用System.Text; 使用System.IO; 使用System.Xml.Serialization;

namespace DeserializeXML {public class Program {

    // This is the class that will be deserialized.
    [Serializable()]
    public class TradeFill
    {
        [XmlElement("Broker")]
        public string broker;

        [XmlElement("qwFillTransID")]
        public string qwFillTransId;

        [XmlElement("qwPrevTransID")]
        public string qwPrevTransId;

        [XmlElement("qwGroupTransID")]
        public string qwGroupTransId;

        [XmlElement("GroupTransID")]
        public string GroupTransID;

        [XmlElement("TransID")]
        public string TransId;

        [XmlElement("Service")]
        public string Service;

        [XmlElement("Exchange")]
        public string Exchange;

        [XmlElement("InstClass")]
        public string InstClass;

        [XmlElement("InstSubClass")]
        public string InstSubClass;

        [XmlElement("ContractSymbol")]
        public string ConSymbol;

        [XmlElement("ExpirationDate")]
        public DateTime ExpDate;

        [XmlElement("Month")]
        public int month;

        [XmlElement("Year")]
        public int year;

        [XmlElement("Strike")]
        public double strike;

        [XmlElement("TradePCU")]
        public string TradePCU;

        [XmlElement("Buy")]
        public int buy;

        [XmlElement("Quantity")]
        public int quantity;

        [XmlElement("Price")]
        public double price;

        [XmlElement("FillTime")]
        public DateTime FillTime;

        [XmlElement("PosUpdated")]
        public string PosUpdated;

    }


    [XmlRootAttribute("TradeFills")]
    public class SIGTrades
    {
        [XmlElement("TradeFills")]
        public TradeFill[] TradeFills{ get; set; }
    }


    [Serializable()]
    public class Test
    {
         public static void Main()
        {
            Test t = new Test();
          // Read a purchase order.
            t.DeserializeObject("c:\\test.xml");
        }

        private void DeserializeObject(string filename)
        {   
            Console.WriteLine("Reading with Stream");
            // Create an instance of the XmlSerializer.
            XmlSerializer serializer =
            new XmlSerializer(typeof(TradeFill));
            // Reading the XML document requires a FileStream.
            Stream reader= new FileStream(filename,FileMode.Open);

            // Declare an object variable of the type to be deserialized.
            TradeFill i;

            // Call the Deserialize method to restore the object's state.
            i = (TradeFill)serializer.Deserialize(reader);

            // Write out the properties of the object.
            Console.Write(i.qwFillTransId);
        }
    }


}

}

当我执行它时,我只在控制台上看到"正在读取流",而没有别的.

我只是意识到我只说"正在阅读",因为它仍在阅读.大约5秒后,这就是我得到的:

将我的Program类公开后,我现在收到此错误:

对我的代码进行了一系列更改(如上所示).有一些项目列出两次,双重检查案件等我现在得到这个错误:

Unhandled Exception: System.InvalidOperationException: There is an error in XML
document (2, 2). ---> System.InvalidOperationException: <TradeFills xmlns=''> wa

Answer 1

尝试改变这个:

class Program
    {

对此

public class Program
    {

如果未指定访问修饰符,则使用默认值 internal
