Description

TEqualityComparer is a generic base for classes that implement the IEqualityComparer interface.

System.Generics.Defaults.TDelegatedEqualityComparer inherits from System.Generics.Defaults.TEqualityComparer. All content below this line refers to System.Generics.Defaults.TEqualityComparer.

TEqualityComparer is a generic base for classes that implement the IEqualityComparer interface.

TEqualityComparer is an abstract class for IEqualityComparer implementations and a provider of default IEqualityComparer implementations.

Use TEqualityComparer as a base for custom equality comparer classes. Both the Equals and GetHashCode methods are abstract and must be implemented in descendant classes.

TEqualityComparer also provides the possibility to create a default comparer for a given data type.
