Got error while reading XML file, XML Document (2,2) contains an error

Question

Got error while reading XML file, XML Document (2,2) contains an error

Rinaldo 396

I created and CS file with XSD.exe with the help of volenteer @Petrus 【KIM】 but now i get the mentioned error at the beginning XML Document (2,2) contains an error. I don't know what this error is for.
The code:

 static XMLInvoice invoice(string file)  
        {  
            XMLInvoice i ;  
  
            string path = file;  
  
            XmlSerializer serializer = new XmlSerializer(typeof(XMLInvoice));  
  
            FileStream fs = new FileStream(file, FileMode.Open);  
            i = (XMLInvoice)serializer.Deserialize(fs);  
            fs.Close();  
            return i;  
}

Hopefully somebody can help

You did not share the XML layout or the XMLInvoice type. The community cannot verify the logic correct. Also, the design does not verify if the file exists which can be a problem. I recommend running the code through the debugger to figure out what's wrong.

If you need community debugging support then share enough code the community can run to produce the same results.

@AgaveJoe I put a part of the XML file here It's a existingfile delivered by the supplier (Universal Bussines Language) file

Answer 1

For demonstration I shorten your XML sample to, (save it to a file on disc)

<?xml version="1.0" encoding="UTF-8"?>
<Invoice xmlns="urn:oasis:names:specification:ubl:schema:xsd:Invoice-2" xmlns:cac="urn:oasis:names:specification:ubl:schema:xsd:CommonAggregateComponents-2" xmlns:cbc="urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2">
  <cbc:ID>03000</cbc:ID>
  <cbc:IssueDate>2021-11-18</cbc:IssueDate>
  <cbc:Note>Klant 6176 Factuur 03000</cbc:Note>
</Invoice>

Class file for XML above will be (Class with Nested Partial Class as you already have)

public class XMLInvoice
  {
    [System.SerializableAttribute()]
    [System.ComponentModel.DesignerCategoryAttribute("code")]
    [System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true, Namespace = "urn:oasis:names:specification:ubl:schema:xsd:Invoice-2")]
    [System.Xml.Serialization.XmlRootAttribute(Namespace = "urn:oasis:names:specification:ubl:schema:xsd:Invoice-2", IsNullable = false)]
    public partial class Invoice
    {
      private ushort idField;
      private System.DateTime issueDateField;
      private string noteField;

      [System.Xml.Serialization.XmlElementAttribute(Namespace = "urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2")]
      public ushort ID
      {
        get
        {
          return this.idField;
        }
        set
        {
          this.idField = value;
        }
      }

      [System.Xml.Serialization.XmlElementAttribute(Namespace = "urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2", DataType = "date")]
      public System.DateTime IssueDate
      {
        get
        {
          return this.issueDateField;
        }
        set
        {
          this.issueDateField = value;
        }
      }

      [System.Xml.Serialization.XmlElementAttribute(Namespace = "urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2")]
      public string Note
      {
        get
        {
          return this.noteField;
        }
        set
        {
          this.noteField = value;
        }
      }
    }
  }

To read XML file and get values, use this

private void GetXMLData()
  {
    XMLInvoice.Invoice MyData;
    string file = @"<place here full apth and name of XML sample file";
    System.Xml.Serialization.XmlSerializer serializer = new System.Xml.Serialization.XmlSerializer(typeof(XMLInvoice.Invoice));
    using (System.IO.Stream reader = new System.IO.FileStream(file, System.IO.FileMode.Open))
    {
      MyData = (XMLInvoice.Invoice)serializer.Deserialize(reader);
    }
    ushort ID = MyData.ID;
    DateTime IssueDate = MyData.IssueDate;
    string Note = MyData.Note;
  }

Run in Debug.....

Answer 2

public class XMLInvoice --> Is right?

xsd.exe creates the xsd class as root (top level).

[System.CodeDom.Compiler.GeneratedCodeAttribute("xsd", "4.8.3928.0")]
[System.SerializableAttribute()]
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType=true, Namespace="urn:oasis:names:specification:ubl:schema:xsd:Invoice-2")]
[System.Xml.Serialization.XmlRootAttribute(Namespace="urn:oasis:names:specification:ubl:schema:xsd:Invoice-2", IsNullable=false)]
public partial class Invoice {

    private string customizationIDField;

    private string profileIDField;

I put a part of the XMLInvoice XML here now.

<?xml version="1.0" encoding="UTF-8"?>
<Invoice xmlns="urn:oasis:names:specification:ubl:schema:xsd:Invoice-2" xmlns:cac="urn:oasis:names:specification:ubl:schema:xsd:CommonAggregateComponents-2" xmlns:cbc="urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2">

When this exception is thrown:
Got error while reading XML file, XML Document (2,2) contains an error

Can you check whether the base exception contains anymore information?

Innereception
System.InvalidOperationException: <Invoice xmlns='urn:oasis:names:specification:ubl:schema:xsd:Invoice-2'> is not expected
bij Microsoft.Xml.Serialization.GeneratedAssembly.XmlSerializationReaderXMLInvoice.Read3_XMLInvoice()

I hope somebody regonize this

By the parts of code, I can only say they not relate each other.
Inner Exception message is telling you where your problem is

System.InvalidOperationException: <Invoice xmlns='urn:oasis:names:specification:ubl:schema:xsd:Invoice-2'> is not expected

Usually I read "XML Document (2,2) contains an error" as Line 2, Char2

Sounds you trying Deserialize right file with incorrect class

Just in case you can also Generate a Class from XML in VS using Edit > Paste Special > Paste XML as Classes

I have tried the option in vs but works only with the supplier where I extract a CLASS from and that is for no other. It fails with the same error: document contain an error

Did a test here and reproduce same error.
In your Class code posted above, you have a Partial Class Nested in a Class, so instead of Deserialize to XMLInvoice you have to use XMLInvoice.<Whatever Partial Class Name you have>.
So instead of XMLInvoice type, try XMLInvoice.Party type

Rinaldo 396

I've removed the partial from the CLASS file. I found something on the net in a old MSDN forum but can't extract the value of the members

static XMLInvoice.Party i = new XMLInvoice.Party();
        static void invoice(string file)
        {

            try
            {
                XmlSerializer xz = new XmlSerializer(typeof(XMLInvoice.Party));
                MemoryStream ms = new MemoryStream();
                xz.Serialize(ms, i);

                ms.Position = 0;
                StreamReader sr = new StreamReader(file);
                //Console.WriteLine(sr.ReadToEnd());        //You can use this to write into a file

                ms.Position = 0;
                i = (XMLInvoice.Party)xz.Deserialize(ms);
                Console.WriteLine(new XMLInvoice.Party().PartyName);
                sr.Close();
            }
