Writing Custom Generic List

Hi,

Many of us know the importance of customizing the exceptions and can achieve this by creating our own Custom Exceptions Classes.
Like wise, Here i provide code to define Own Generic List class.

Usually, to take list of strings, we can use
List<string> oStringList=new List<string>();
and then we can perform some predefined operations like, Sort, reveres etc, on it.

Here, i want to use my customized list
for ex : CustomList<string> cStringlist = new CustomList<string>();
and want to perform customized operations like AddToList(), RemoveFromList(), showCustomListData()

Code:

//my custom generic class
    public class CustomList<T>
    {
        T[] listData;
        int listCount;
        public int length;
        public CustomList()
        {
            listData = new T[10];
            listCount = 0;
            length = listCount;
        }
        public void AddToList(T Data)
        {
            if (listCount < 10)
            {
                listData[listCount] = Data;
                listCount = listCount + 1;
                length = listCount;
            }
            else
            {
                try
                {
                    Console.WriteLine("Invalid operation since  data in CustomList is FULL");
                    Console.WriteLine("{0}", Environment.NewLine);
                    throw new CustomException("List data is Full");
                }
                catch (CustomException Ex)
                {
                    Console.WriteLine("{0}", Environment.NewLine);
                    Console.WriteLine("{0}", Environment.NewLine);
                    Console.WriteLine("List Data is full.. U wil not proceed furthur{0}{1}", Environment.NewLine, Ex); ;
                }
            }
        }
        public void RemoveFromList()//removes last inserted data
        {
            if (listCount > 0)
            {
                listCount = listCount - 1;
                length = listCount;
                Console.WriteLine("Successfully removed From CustomList");
                return;
            }
            else
            {
                Console.WriteLine("invalid operation since No data in CustomList ");
                return;
            }
        }
        public T showCustomListData(int position)
        {
            return (T)listData[position];
        }
        ~CustomList()
        {
            this.listData = null;
            listCount = 0;
            GC.Collect();
        }
    }

How to call:

CustomList<string> cStringlist = new CustomList<string>();//you can use int,string etc...
            
            cStringlist.AddToList("Hi");
           
            
            cStringlist.AddToList("Hello");
            
            cStringlist.AddToList("Welcome To");
            
            cStringlist.AddToList("dotnetfunda");
            
            cStringlist.AddToList(".com");
            
            cStringlist.RemoveFromList();//removes '.com'
            Console.WriteLine("{0}", Environment.NewLine);
            for (int i = 0; i < cStringlist.length; i++)
            {
                Console.WriteLine("Data in Custom List strings  are:{0}", cStringlist.showCustomListData(i).ToString());
            }

Thank you.
