Comparing Lists of Different Lengths

Sometimes lists, arrays, and dictionaries are equal to each other but they are in a different order. The Config.IgnoreCollectionOrder property can be used to compare lists that are not only out of order but also of different lengths. There is a huge performance decrease 🐌 when Ignoring the Collection Order. This may be okay if you are comparing a few hundred objects at a time. By default all the simple type properties are used as a key for an object. To minimize the performance impact, define a Config.CollectionMatchingSpec. This defines the key for the object.

Example

CompareLogic logic = new CompareLogic();
logic.Config.IgnoreCollectionOrder = true;

var spec = new Dictionary<Type, IEnumerable<string>>();
spec.Add(typeof(Customer), new string[] { "CustomerId" });
logic.Config.CollectionMatchingSpec = spec;
