Any suggestions as to how I can force removal of the object or prove that it has been removed?

ArrayList is not as efficient as List but I will use it for the output table list since it there will be a number of different table types and as long as they have a large number of common methods it is an easy method of keeping the tables in sequence

public interface ITable
{
    int IntProperty { get; set; }

    void RandomMethod();
}

public class TableA : ITable
{
    public int IntProperty
    {
        get;
        set;
    }

    public void RandomMethod()
