Access: Read-Only

Value:

A default generic equalityComparer for type T. The procedure is as follows:

If T is int, double, byte or char, the equalityComparer will be a standard equalityComparer for that type
If the actual generic argument T implements the generic interface ISequenced<T> for some value W of its generic parameter T, the equalityComparer will be SequencedCollectionEqualityComparer<T,W>
If the actual generic argument T implements ICollectionValue<T> for some value W of its generic parameter T, the equalityComparer will be UnsequencedCollectionEqualityComparer<T,W>
If T is a type implementing , the equalityComparer will be EquatableEqualityComparer<T>
If T is a type not implementing , the equalityComparer will be NaturalEqualityComparer<T>

The object is constructed when this class is initialised, i.e. its static constructors called. Thus, the property will be the same object for the duration of an invocation of the runtime, but a value serialized in another invocation and deserialized here will not be the same object.
