  The implementation details for value equality are different for classes and structs. However, both classes and structs require the same basic steps for implementing equality:

(See step 2.)  
 
 2.  Implement the <xref:System.IEquatable%601?displayProperty=fullName> interface by providing a type-specific `Equals` method. This is where the actual equivalence comparison is performed. For example, you might decide to define equality by comparing only one or two fields in your type. Do not throw exceptions from `Equals`. For classes only: This method should examine only fields that are declared in the class. It should call `base.Equals` to examine fields that are in the base class. (Do not do this if the type inherits directly from <xref:System.Object>, because the <xref:System.Object> implementation of <xref:System.Object.Equals%28System.Object%29?displayProperty=fullName> performs a reference equality check.)
