class System.Collections.Generic.ReferenceEqualityComparer
Assembly: System.Collections
Inheritance: object → ReferenceEqualityComparer
Implemented Interfaces
An <see cref="T:System.Collections.Generic.IEqualityComparer`1" /> that uses reference equality ( <see cref="M:System.Object.ReferenceEquals(System.Object,System.Object)" /> ) instead of value equality ( <see cref="M:System.Object.Equals(System.Object)" /> ) when comparing two object instances.
