Objects that doesn't own unmanages resources (or objects that implement IDisposable) don't need a Dispose method or a finalizer. You can just remove the reference to your object (or let it go out of scope), and the object will be freed by the garbage collector eventually.

public void F()
{
    Object obj = new Object();
    // Do some stuff with the object
    obj = null;
}

If no finalizer is present, where than should I remove the reference to my object?

Class A {
   private List<string> _list;
   public A() {
      _list = new List<string>();
   }
   public List<string> List { get { return _list; } }
   public Add(string s) {
      _list.Add(s);
   }
}

Also, is the last statement in the following code redundent?
I think of it as a good programming practice, as you can be sure that the reference was removed.

public void F()
{
Object obj = new Object();
// Do some stuff with the object
obj = null;
}

i want to access the record value on a specific location in the datatable by specifying the row and column number, and then retrieving the value on that particular locaion.

DataRow row = myTable.Rows[rowIndex];

object value = row[columnIndex];
