Equivalent classes are used by some contract verifiers such as EqualityContract<(Of <(TTarget>)>) and ComparisonContract<(Of <(TTarget>)>) to check for the correct implementation of object equality or comparison.

Use the default constructor followed by a list initializer to create a collection of equivalence classes which contains a variable number of object instances.

CopyC#

var collection = new EquivalenceClassCollection
{
    { new Foo(1), new Foo("One") },
    { new Foo(2), new Foo("Two") },
    { new Foo(3), new Foo("Three") }
};

Use the single-parameter constructor to create a collection of equivalence classes which contains one single object instance each.

CopyC#

var collection = new EquivalenceClassCollection(new Foo(1), new Foo(2), new Foo(3));
