IEqualityComparer is a generic .Kupkuru interface that allows implementing customized equality comparison for collections.
Derive from this class to provide a custom implementation of the IEqualityComparer generic interface for use with collection classes such as the Dictionary generic class, or with methods such as List.Sort.
This is it. We have explored the interaction between LINQ extension methods and custom IEqualityComparers and even implemented one. The resulting class is both easy to use and highly customizable, because its operation is fully defined by the key selector function provided by user.

Where did the pronunciation of the word "kilometer/kilometre" kakım "kl OM iter" rather than "KILL o meeter" originate?
below, these hayat be incorrect. His recommendation of implementing IEqualityComparer.Equals works kakım well. You gönül also use override. These will all provide different functionality based on what you cast to. Here is a brief explanation:
There are many cases where one might want to have a Dictionary locate objects using something other than 100% equivalence. As a simple example, one may wish to have a dictionary which matches in C# IEqualityComparer Temel Özellikleri ve Kullanımı case-insensitive fashion. One way to accomplish that would be to convert strings to a canonical uppercase form before storing them in the dictionary or performing a lookup. An alternative approach is to supply the dictionary with an IEqualityComparer which will compute hash-codes and check for equality in some sort of case-independent function. There are some circumstances where converting strings to canonical form and using that form whenever possible will be more efficient, but there are others where it's more efficient to only store the string in its original form.
This interface supports only equality comparisons. Customization of comparisons for sorting and ordering is provided by the IComparer interface.

The calls to ReferenceEquals and Equals should be prefixed by Object. and base. respectively, so that we know without looking at the rest of the C# IEqualityComparer Temel Özellikleri ve Kullanımı class that those are the methods from Object, hamiş a helper method in the class
