Question

我正在尝试反序列化在线XML文件并将结果写入数据库。但是，我收到以下错误：

“ System.InvalidOperationException：'XML文档中存在错误（2，2）”

内部异常

“ InvalidOperationException：http://deutsche-boerse.com/dbag/app/open/xetra'>不是预期”

下面是我的代码：

        class Program
        {
            public static void Main()
            {
                Program semoAPI = new Program();
    //Intraday Market Results
                using (WebClient webClient = new WebClient())
                {
                    WebClient n = new WebClient();

                    var json = n.DownloadString("https://reports.semopx.com/api/v1/documents/static-reports?" +
                    "page=1&page_size=1&order_by=ASC&ReportName=Intraday%20Market%20Results%20Order&Group=Market%20Data");

                    SemoReports semoReports = JsonConvert.DeserializeObject<SemoReports>(json);


                    Console.WriteLine("Intraday Market Results Report: ");
                    Console.WriteLine(semoReports.ResourceBaseUri + "/" + semoReports.Items[0].ResourceName);

                    string imrXML = semoReports.ResourceBaseUri + "/" + semoReports.Items[0].ResourceName;

                    XDocument document = XDocument.Load(imrXML);

                    semoAPI.DeserializeIntradayMarketResults(imrXML);
                }
            }


 //IntradayMarketResults to Database
    private void DeserializeIntradayMarketResults(string filename)
    {
        //Visual only not needed
        Console.WriteLine("\n" + "Reading IntradayMarketResults XML File");
        Console.WriteLine("===========================================================");



        // Create an instance of the XmlSerializer.
        XmlSerializer serializer = new XmlSerializer(typeof(IntradayMarketResults));

        // Declare an object variable of the type to be deserialized.
        IntradayMarketResults item;

        using (XmlReader reader = XmlReader.Create(filename))
        {
            // Call the Deserialize method to restore the object's state.
            item = (IntradayMarketResults)serializer.Deserialize(reader);

                //Write out the properties of the object. (Visual Only, not needed)
                Console.Write(
                   item.IMRReportHeader[0].exchNam + "\t" +
                   item.IMRReportHeader[0].envText + "\t" +
                   item.IMRReportHeader[0].rptCod + "\t" +
                   item.IMRReportHeader[0].rptName + "\t" +
                   item.IMRReportHeader[0].rptPrntEffDat + "\t" +
                   item.IMRReportHeader[0].rptPrntRunDat + "\n \n \n");

                //write the properties to the db 
                using (SEMOContext context = new SEMOContext())
                {
                    context.IntradayMarketResultsReports.Add(item);
                    context.SaveChanges();
                }
        }

这也是我设置课程的方式：

public class IntradayMarketResults
    {
        public IMRReportHeader[] IMRReportHeader { get; set; }
    }

[XmlRoot(ElementName = "rptHdr")]
    public class IMRReportHeader
    {
        [Key]
        public int RrportID { get; set; }
        public string exchNam { get; set; }
        public string envText { get; set; }
        public string rptCod { get; set; }
        public string rptName { get; set; }
        public string rptPrntEffDat { get; set; }
        public string rptPrntRunDat { get; set; }
    }

我尝试过的事情：

我尝试将以下内容添加到课程中

[Serializable, XmlRoot("tc540")]

我也尝试过：

[XmlRoot(ElementName = "tc540", DataType = "string", IsNullable = false)]

还尝试在运行时添加：

//Root error fix
            XmlRootAttribute xRoot = new XmlRootAttribute();
            xRoot.ElementName = "tc540";
            //xRoot.Namespace = "https://deutsche-boerse.com/dbag/app/open/xetra";
            xRoot.IsNullable = true;

XmlSerializer serializer = new XmlSerializer(typeof(IntradayMarketResults), xRoot);

最后我尝试了：

 XmlSerializer serializer = new XmlSerializer(typeof(IntradayMarketResults), new XmlRootAttribute("tc540"));

即使尝试了所有这些解决方案，我仍然会收到相同的错误消息。

我要反序列化的XML文件链接：https://reports.semopx.com/documents/IDC_OrderFile_20190331_20190401053002.xml

PS。我知道这段代码可以正常工作，因为它可以使用相同的API处理更简单的XML文件。我也知道console.writeline行在调试时不需要为了视觉目的。

我似乎无法使它适用于更复杂的XML文件。

感谢您的任何帮助！
