Cannot compare collections with items of different types

The library doesn’t work correctly in case when you compare lists with items of different types. You are getting an exception like the following:

System.Exception : Invalid CollectionMatchingSpec.  No such property XXXXProperty for type YYYYYClass

If you set IgnoreCollectionOrder = true it works better but in some situations you also receive the exception below.

You will need to specify a collection matching spec for both types:

    [Test]
    public void CompareListsIgnoreOrderTwoDifferentTypes()
    {
        List<Person> list1 = new List<Person>();
        list1.Add(new Person() {ID = 1, Name = "Logan 5"});
        list1.Add(new Person() { ID = 2, Name = "Francis 7" });

        List<Officer> list2 = new List<Officer>();
        list2.Add(new Officer() { ID = 2, Name = "Francis 7" });
        list2.Add(new Officer() { ID = 1, Name = "Logan 5" });

        ComparisonConfig config = new ComparisonConfig();
        Dictionary<Type, IEnumerable<string>> collectionSpec = new Dictionary<Type, IEnumerable<string>>();
        collectionSpec.Add(typeof(Person), new string[] { "ID" });
        collectionSpec.Add(typeof(Officer), new string[] { "ID" });

        config.IgnoreObjectTypes = true;
        config.IgnoreCollectionOrder = true;
        config.CollectionMatchingSpec = collectionSpec;

        CompareLogic compareLogic = new CompareLogic(config);
        var result = compareLogic.Compare(list1, list2);
        Assert.IsTrue(result.AreEqual);
    }

@PalashBansal Sorry the Compare .NET Object Library is not going to work for something like this. You will need to write your own comparison code.
