xaml parse exception occurs in Visual studio on deserialization of xml to create object

Question

I am working on c# using silverlight-5 in VS2012 and trying to derialize.

My code to do this is as follows :

Filename is `attribute.cs`
    using System;
    using System.Net;
    using System.Windows;
    using System.Windows.Controls;
    using System.Windows.Documents;
    using System.Windows.Ink;
    using System.Windows.Input;
    using System.Windows.Media;
    using System.Windows.Media.Animation;
    using System.Windows.Shapes;
    using System.Runtime.Serialization.Json;
    using System.Runtime;
    using System.Xml.Serialization;
    using System.Runtime.Serialization;
    using System.IO;
    using System.Collections.Generic;
    using System.Diagnostics;



    namespace Model.XML
    {
        [DataContract]
        public class attribute
        {
            [DataMember]
            public string type { get; set; }

            [DataMember]
            public string displayed { get; set; }

            [DataMember]
            public string add_remove { get; set; }

            [DataMember]
            public string ccypair { get; set; }

            [DataMember]
            public List<int> item { get; set; }

            public static void Main()
            {
               // System.IO.StreamReader myFileStream = new System.IO.StreamReader("C:\\Users\\SHEK\\Desktop\\VannakNew\\DEV_CENTER\\Model\\XML\\XmlParameter.xml");
                FileStream myFileStream = new FileStream(@"\XmlParameter.xml", FileMode.Open); //On debugging after this line the code breaks and generate exception
                attribute mainobj = null;
                XmlSerializer ser = new XmlSerializer(typeof(attribute));
                mainobj = ser.Deserialize(myFileStream) as attribute;
                Debug.WriteLine(mainobj.type);  
            }        
        }
    }

Just after the line FileStream myFileStream = new FileStream(@"C:\Users\SHEK\Desktop\VannakNew\DEV_CENTER\DEV_CENTER\Parameters.xaml", FileMode.Open); it switches to the MainPage.Xaml.cs and there it shows this exception .

Why it do so ? What i hav to do is : I have an xml file and there is a class called attricute.cs in xml file i have to display it's node elements. The xml file is as follows:

<?xml version="1.0" encoding="utf-8" ?>
<parameter>
  <name>bands_amounts</name>
  <label>Bands Amounts</label>
  <unit></unit>
  <component>
    <type>List</type>
    <attributes>
      <type>Integer</type>
      <displayed>4</displayed>
      <add_remove>yes</add_remove>
      <item>1 000 000</item>
      <item>5 000 000</item>
      <item>10 000 000</item>
      <item>20 000 000</item>
    </attributes>
    <attributes>
      <ccypair>XAUUSD</ccypair>
      <item>100</item>
      <item>500</item>
      <item>1000</item>
    </attributes>
  </component >
</parameter>

EDIT AFTER COMMENTS: I changed my code to this after reading the comments but the problem is it even dont executes any line after FileStream myFileStream = new FileStream(@"\XmlParameter.xml", FileMode.Open); it directly show that exception again.

        public string displayed { get; set; }

        [DataMember]
        public string add_remove { get; set; }

        [DataMember]
        public string ccypair { get; set; }

        [DataMember]
        public List<int> item { get; set; }

        public static void Main()
        {
           // System.IO.StreamReader myFileStream = new System.IO.StreamReader("C:\\Users\\SHEK\\Desktop\\VannakNew\\DEV_CENTER\\Model\\XML\\XmlParameter.xml");
            FileStream myFileStream = new FileStream(@"\XmlParameter.xml", FileMode.Open);

            attribute mainobj = null;
            XmlSerializer ser = new XmlSerializer(typeof(parameter));
            mainobj = ser.Deserialize(myFileStream) as attribute;
            Debug.WriteLine(mainobj.type);  
        }        
    }
}

Answer 1

The type that you pass to XmlSerializer as the root type represents the root of the xml. You are passing typeof(attribute). This type does not match the xml; you should be passing typeof(Parameter) i.e. a type that looks like the xml. For example:

[XmlRoot("parameter")]
public class Parameter {
    [XmlElement("component")]
    public Component Component {get;set;}
}

(edit, see comments) another file

public class Component {
    [XmlElement("attributes")]
    public List<Attribute> Attributes {get;set;}
}

with:

XmlSerializer ser = new XmlSerializer(typeof(Parameter));
var mainobj = (Parameter)ser.Deserialize(myFileStream);
