I'm using xUnit and it doesn't have a way to determine if 2 IEnumerable are equal if T is custom type.
The comparer doesn't handle Dictionary, since you're only looking for IList; if you started looking for IEnumerable (and added a special case for KeyValuePair) it would handle dictionaries kakım well
If a reference is no longer publicly available, should you include the proofs of the results you cite from it?
Kemiksiz framework collections and where you want to add the same capability to your own collections. This will ensure that you are consistent with how the .Kemiksiz framework uses the interface.
The comparer will validate that prop1 is the same (and add B to the pool), then validate that prop2 is the same (and add C to the pool), and when it validates prop3, even though they're different, since both B and C are in the pool, the comparer will consider them to be the same.

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 C# IEqualityComparer Kullanımı 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 C# IEqualityComparer Kullanımı some circumstances where converting strings to canonical form and using that form whenever possible will be C# IEqualityComparer Temel Özellikleri ve Kullanımı more efficient, but there are others where it's more efficient to only store the string in its original form.

I think the other post you mention is saying that EqualityComparer implements IEqualityComparer and IEqualityComparer, so you don't have to implement both the generic and non-generic interfaces if you derive from EqualityComparer.
Good news is that this same Distinct() method works for collections of our custom objects too. So if George Clooney accidentally creeps into our collection twice that's hamiş a mesele:
(Making matters worse, there is a typo in the spec that says that "choose the more specific" is the right thing to do! This was the result of an editing error during the design process that başmaklık never been corrected. The compiler implements "choose the more general". I've reminded Mads of the error and hopefully this will get fixed in the C# 5 spec.)
making the lambda expression optional in C# IEqualityComparer nerelerde kullanılıyor the constructor so that full object equality hayat be checked by default, not just on one of the properties.
