Implement generic objects comparing in C#

I'm implementing generic objects comparing method to compare instances of classes in my project. In each class I have some value type variable and some bindinglist of its associate class. With value type variable, I can use == operator or equal operator to compare it, but with bindinglist, I don't know how to cast it to bindinglist<type of associate class> to iterate through it and perform recursion.

public bool IsEqual<T>(T obj1, T obj2)
{
    PropertyInfo[] prop1 = obj1.GetType().GetProperties();
    PropertyInfo[] prop2 = obj2.GetType().GetProperties(); 

    for(int i = 0; i < prop1.Count; i++)
    {
        if(prop1[i].IsValueType && prop2[i].IsValueType)
        {
            if(prop1.GetValue(i) != prop2.GetValue(i))
                return false
        }
        else
        {
            //This is bindinglist of associate class
            //I need to cast it to iterate in perform recursion here            
        }
    }

    return true
}

So how can I implement recursion when property is a bindinglist?

P/S: forgive my bad English

UPDATE:

After consider carefully, I implemented IEqualtable as Mr. Stephen Hewlett suggested. Thank you very much, Mr. Stephen Hewlett. And for those who still want to use compare function, I'll give you an approach that I think it will work:

public bool IsEqual(Object obj1, Object obj2)
{
    PropertyInfo[] prop1 = obj1.GetType().GetProperties();
    PropertyInfo[] prop2 = obj2.GetType().GetProperties(); 

    for(int i = 0; i < prop1.Count; i++)
    {
        if(prop1[i].IsValueType && prop2[i].IsValueType)
        {
            if(prop1[i].GetValue(obj1, null) != prop2[i].GetValue(obj2, null))
                return false;
        }
        else if (prop1[i].PropertyType.IsGenericType && prop2[i].PropertyType.IsGenericType) //if property is a generic list
        {
            //Get actual type of property
            Type type = prop1[i].PropertyType;

            //Cast property into type
            var list1 = Convert.ChangeType(prop1[i].GetValue(obj1, null), type);
            var list2 = Convert.ChangeType(prop1[i].GetValue(obj2, null), type);

            if (list1.count != list2.count)
                return false;

            for j as integer = 0 to list1.Count - 1
            {
                //Recursion here
                if (!IsEqual(list1(j), list2(j)))
                {
                    return false;
                }
            }
        }
        else //if property is instance of a class
        {
            Type type = prop1[i].PropertyType;
            Object object1 = Convert.ChangeType(prop1[i].GetValue(obj1, null), type);
            Object object2 = Convert.ChangeType(prop1[i].GetValue(obj2, null), type);

            //Recursion
            if(!IsEqual(object1, object2))
            {
                 return false;
            }
        }
    }

    return true;
}
