Deep Cloning of Collections(Key/Value Pair) using Reflection

I am using below class to do the Deep cloning with out serialization.

  public class AbstractClone
{

    public AbstractClone Clone()
    {
        Type typeSource = this.GetType();
        AbstractClone tObject = (AbstractClone)FormatterServices.GetUninitializedObject(typeSource);

        PropertyInfo[] propertyInfo = typeSource.GetProperties(BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance);

        foreach (PropertyInfo property in propertyInfo)
        {
            if (property.CanWrite)
            {

                if (property.PropertyType.IsValueType || property.PropertyType.IsEnum || property.PropertyType.Equals(typeof(System.String)))
                {
                    property.SetValue(tObject, property.GetValue(this, null), null);
                }
                else
                {
                    object objPropertyValue = property.GetValue(this, null);

                     if (objPropertyValue == null)
                    {
                        property.SetValue(tObject, null, null);
                    }
                    else
                    {
                        property.SetValue(tObject, ((AbstractClone)objPropertyValue).Clone(), null);
                    }
                }
            }

        }
        return tObject;
    }
}

I am inheriting all the classes from this which needs to be cloned.

This works fine with all the objects except key Value Pairs or collections like SortedList,Dictionary etc

Could anyone suggest a way to clone the KeyValue pairs like SortedList of Dictionary.
