simple xml de-serializer test    
Hi,

I am trying to read my xml file and output in console prompt.
I get the error message: "There is an error in XML document (2, 2)."
I'm not very sure what this message means. Any advice would be appreciated.
cheers
Andrew

code
====
static void Main(string[] args)
 {
  clsProduct p  = new clsProduct();
   XmlSerializer reader = new XmlSerializer(p.GetType());
   System.IO.StreamReader file = new 
System.IO.StreamReader(@"C:\Output\Product.xml");
   p = (clsProduct) reader.Deserialize(file); <-- ERROR LINE

   Console.Write(
    p.ItemName + "\t" +
    p.Description + "\t" +
    Convert.ToString(p.UnitPrice) + "\t" +
    Convert.ToString(p.Qty) + "\t" +
    Convert.ToString(p.LineTotal));
    Console.ReadLine();
 }

Product.xml

<?xml version="1.0" encoding="utf-8"?>

        }

        public string Description
        {
            get { return Description; }
            set { Description = value; }
        }
        
        public decimal UnitPrice
        {
            get { return UnitPrice; }
            set { UnitPrice = value; }
        }

        [XmlElement(ElementName="Quantity")]
        public int Qty
        {
            get { return Qty; }
            set { Qty = value; }

Well the serializer looks for an element of the class name, unless you 
specify it differently

However you have more serious problems in all your properties, they will 
lead to a stack overflow as they are recursive.
So replace that code with e.g.
           private string itemName;
           public string ItemName
           {
               get { return itemName; }
               set { itemName = value; }
           }
and do the same for the other properties.

Re: simple xml de-serializer test    
Thanks it works beautifully.

I modified the code to deserialize a larger xml file which goes something 
like this:
Is the code the same to de-serialize ?

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <soap:Body>
    <GetResultResponse xmlns="http://Product/Books/Store/V2">
      <InvestigationReport>
        <ReportData xmlns="http://Product/Books/Store">
          <ServiceProvider />
          <RequestingParty>
            <HcpId xmlns="http://Product/Books/General">
              <IdValue>ABC001</IdValue>
              <IdScheme>Requestor</IdScheme>
              <IdType>Administrator</IdType>
            </HcpId>
        </DocumentData>
      </InvestigationReport>
    </GetResultResponse>
  </soap:Body>
</soap:Envelope>

Thanks

That is SOAP so you might want to look into SOAP serialization

Re: simple xml de-serializer test    
Hi,

Thanks for your reply. From what I've read, the code is different for SOAP 
Serialization, but for de-serialization, it's essentially the same. Am I 
right ?

What I need to figure out is which is the SoapType, XMLRoot, XmlType, etc 
tags...

cheers
Andrew

Re: simple xml de-serializer test    
Hi,
I got a parse error "Parse Error, no assembly associated with Xml key _P1 
GetResultResponse" with this code:

 using System.Xml;
 using System.Xml.Serialization;
 using System.Runtime.Serialization;
 using System.Runtime.Serialization.Formatters.Soap;

 IFormatter formatter;
 FileStream fileStream = null;
 Object objectFromSoap = null;
  try
  {
    string filePath = @"C:\FileStore\Result.xml";            
    fileStream = new FileStream(filePath, FileMode.Open, FileAccess.Read);
    formatter = new SoapFormatter();
    objectFromSoap = formatter.Deserialize(fileStream); <-- error

    Console.Write(objectFromSoap.ToString());
    Console.ReadLine();
  }

Any advice ?

cheers
Andrew
