IEquatable Generic Interface

Note: This interface is new in the .NET Framework version 2.0.

Defines a generalized method that a value type or class implements to create a type-specific method for determining equality of instances.

Namespace: System
Assembly: mscorlib (in mscorlib.dll)

public interface IEquatable<T>
J# supports the use of generic types and methods, but not the declaration of new ones.
JScript does not support generic types and methods.

This interface is implemented by types whose values can be equated (for example, the numeric and string classes). A value type or class implements the Equals method to create a type-specific method suitable for determining equality of instances.

NoteNote

The IComparable interface defines the CompareTo method, which determines the sort order of instances of the implementing type. The IEquatable interface defines the Equals method, which determines the equality of instances of the implementing type.

Notes to Implementers Replace the type parameter of the IEquatable interface with the type that is implementing this interface.
