Problem while converting class object to string using XmlSerializer

nagendrathecoder

Hi All, I am trying to convert a class object into a string of xml format using XmlSerializer. My class structure is like this:

namespace test
{
public class Class1
{
public Class1(){}

	private string strStatus = "Active";		
	public string Status
	{
		get { return strStatus; }
		set { strStatus = value;}
	}
	public Class2 Class2 { get; set; }		
}

public class Class2
{
	public Class2(){}

	private string strName = "ABC";
	public string Name
	{
		get { return strName; }
		set { strName = value; }
	}
	public Class3 Class3 { get; set; }
}

public class Class3()
{
	ArrayList Element;
	private int intCount = 0;

	public Class3()
	{
		Element = new ArrayList();
	}
	public int Count
	{
		get { return intCount;}			
	}
	public void Add(Class4 Entry)
	{
		Element.Add(Entry);
		intCount++;
	}
	
	public Class4 this\[int index\]
	{
		get
		{
			return (Class4)Element\[index\];
		}
	}
}

public class Class4
{
	public Class4(){}

	private int intSub1;
	private int intSub2;

	public int Sub1
	{
		get {return intSub1;}
		set {intSub1 = value;}
	}
	public int Sub2
	{
		get {return intSub2;}
		set {intSub2 = value;}
	}
}

}

Now, i am using this code for converting object of Class1 to a string of xml format:

Class1 objClass1 = new Class1();
Class4 objClass4 = new Class4();
objClass4.Sub1 = 68;
objClass4.Sub2 = 73;
objClass1.Class2.Class3.Add(objClass4);

Class4 objClass4Dup = new Class4();
objClass4Dup.Sub1 = 76;
objClass4Dup.Sub2 = 65;
objClass1.Class2.Class3.Add(objClass4Dup);

System.Xml.Serialization.XmlSerializer x = new XmlSerializer(objClass1 .GetType());
StringWriter sw = new StringWriter();
x.Serialize(sw, objClass1);
string strxml = sw.ToString();
MessageBox.Show(strxml);

In the messagebox, i can see values till Class2 properly in xml format. Then i can see the "Count" of Class3 and its value, but the values of Class4 are not coming into string. Can anybody tell what i am missing or what i need to do to display values of Class4 into string? Thanks, Nagendra.

You must make a public property for Element in Class3.

Hi,thanks for replying. I am using Indexer for getting the indexed based value of Element.

Hi, I added a public property for Element in Class3 as:

public ArrayList GetElement
{
get
{
return Element;
}
}

But i am getting an error as "An error occured while creating Xml Document".

Thanks for replying. I have solved it using the same property. I just gave the xml attribute to the property definning its type and its working now. :)
