  The <xref:System.IEquatable%601> interface is used by generic collection objects such as <xref:System.Collections.Generic.Dictionary%602>, <xref:System.Collections.Generic.List%601>, and <xref:System.Collections.Generic.LinkedList%601> when testing for equality in such methods as `Contains`, `IndexOf`, `LastIndexOf`, and `Remove`. It should be implemented for any object that might be stored in a generic collection.

 ## Examples  
  The following example shows the partial implementation of a `Person` class that implements <xref:System.IEquatable%601> and has two properties, `LastName` and `NationalId`. `NationalId` is considered to be a unique identifier, therefore the <xref:System.IEquatable%601.Equals%2A> method returns `True` if the `NationalId` property of two `Person` objects is identical; otherwise, it returns `False`.  
- Note that the F# example does not handle `null` values for `Person` instances.
