Hi...
I have a fixed size array in my program.....
but in order to make the program memory efficient....
i want to make it an ArrayList...
can someone please explain how to do this.....
i have posted my code below...

class StaticColumn
    {
        public TextBox[] textBoxes = new TextBox[1000];

        public void getDetails(XmlNode node)
        {
            XmlElement nodeAsElement = node as XmlElement;
            XmlNodeList _list = nodeAsElement.GetElementsByTagName("Textbox");
            int i=0;
            foreach (XmlNode tempNode in _list)
            {
                textBoxes[i] = new TextBox();
                textBoxes[i].getDetails(tempNode);
                i++;
            }

                                    
        }
    }
class TextBox
    {
        public string name = string.Empty;
        public string value = string.Empty;
        public string visibility = string.Empty;
        public Navigation navigation = new Navigation();

        public void getDetails(XmlNode node)
        {
            XmlElement nodeAsElement = node as XmlElement;

            try { name = node.Attributes["Name"].InnerText.ToString(); }
            catch (NullReferenceException e)            {            }

            try { value = nodeAsElement.GetElementsByTagName("Value")[0].InnerText.ToString(); }
            catch (NullReferenceException e) { }

            try { visibility = nodeAsElement.GetElementsByTagName("Visibility")[0].InnerText.ToString(); }
            catch (NullReferenceException e) { }

            try { visibility = nodeAsElement.GetElementsByTagName("Hidden")[0].InnerText.ToString(); }
            catch (NullReferenceException e) { }

            try
            {
                navigation = new Navigation();
                node = nodeAsElement.GetElementsByTagName("Drillthrough")[0];
                navigation.getDetails(node);
            }
            catch (NullReferenceException e) { navigation = null; }
            
        }

        public void getElements(XmlNode node)
        {
            XmlElement nodeAsElement = node as XmlElement;

            try { name = node.Attributes["Name"].InnerText.ToString(); }
            catch (NullReferenceException e) { }

            try { visibility = nodeAsElement.GetElementsByTagName("Visibility")[0].FirstChild.InnerText.ToString(); }
            catch (NullReferenceException e) { }

            //try { visibility = nodeAsElement.GetElementsByTagName("Hidden")[0].InnerText.ToString(); }
            //catch (NullReferenceException e) { }

            try
            {
                navigation = new Navigation();
                node = nodeAsElement.GetElementsByTagName("Drillthrough")[0];
                navigation.getDetails(node);
            }
            catch (NullReferenceException e) { navigation = null; }

            try
            {
                nodeAsElement = (XmlElement)nodeAsElement.GetElementsByTagName("Paragraphs")[0];
                XmlNodeList _list1 = nodeAsElement.GetElementsByTagName("Value");
                foreach (XmlNode tempNode in _list1)
                {
                    value = value + tempNode.InnerText.ToString();
                }
            }
            catch (NullReferenceException e) { }
        }

    }

i also want to know how to read from the new class .. Because i'm sure the changes would also affect the reading...

check these link may be helpful 1st link.... 2nd link

hi...
i have already seen these links....
what i need is to create array list of custom classes.....
thanks anyways....

check these link may be helpful 1st link.... 2nd link

what i mean is i need a more detailed explanation.....
the explanation given there is quite simple and it is for a simple list....
i want to know how to do it wen i am doing it with a custom class with lots of variables...
like the example i posted.....

what i am asking is......
if i have to make :-

public TextBox[] textBoxes = new TextBox[1000];

AS

public List<TextBox> textBoxes = new List<TextBox>();

what are the changes i'll have to make to the textbox class to read and write data.....

I have found a solution....
All i have to do is this...

class StaticColumn
    {
        public System.Collections.ArrayList textBoxes = new System.Collection.ArrayList();

        public void getDetails(XmlNode node)
        {
            XmlElement nodeAsElement = node as XmlElement;
            XmlNodeList _list = nodeAsElement.GetElementsByTagName("Textbox");
            int i=0;
            foreach (XmlNode tempNode in _list)
            {
                TextBox t = new TextBox();
                t.getDetails(tempNode);
                textBoxes.Add(t);
            }

                                    
        }
    }
