This transformation allows for faster comparison of elements during look-up, because the elements of the second grup are easier to compare and because there are fewer of them. Still, due to this same reason any hash function might eventually produce equal codes for non equal objects
The CompareTo method would be the default way of ordering your User class, perhaps comparing by Name. If you then decided that you wanted to sort a list of User objects by another property, say Age, you could write a class that implemented IComparer instead of altering CompareTo inside User. This would perform the custom sorting, for example:

Implementations are required to ensure that if the Equals(T, T) method returns true for two objects x and y, then the value returned by the GetHashCode(T) method for x must equal the value returned for y.
The second form is logical equality. Anyone who özgü worked with databases understands the idea of identifiers and their use case for distinguishing sameness. Developers define reasons for equality in code, but the logic can be composed of smaller precise equality comparisons.
Where did the pronunciation of the word "kilometer/kilometre" as "kl OM iter" rather than "KILL o meeter" originate?
Programcının kullanılacak parametre nüshası üzerine herhangi bir ön bilgisinin olmadığı durumlarda.
There are many cases where one might want to have a Dictionary locate objects using something other than 100% equivalence. Kakım a simple example, one may wish to have a dictionary which matches in 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 C# IEqualityComparer Nasıl Kullanılır 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.
Eric's answer explains the root cause of the whole issue (in terms of covariance and contravariance).
