See Also: IEqualityComparer Members
This interface allows the implementation of customized equality comparison for collections. That is, you can create your own definition of equality, and specify that this definition be used with a collection type that accepts the IEqualityComparer interface. In the .NET Framework, constructors of the Hashtable, System.Collections.Specialized.NameValueCollection, and System.Collections.Specialized.OrderedDictionary collection types accept this interface.
This interface supports only equality comparisons. Customization of comparisons for sorting and ordering is provided by the IComparer interface.
For the generic version of this interface, see IEqualityComparer`1.
