The mesele is (and this is why I chose the IList in the first place) that at compile time I don't know the value of T. $endgroup$

1 Foo should be immutable if you intend to use it bey key in hash tables. An in that case new properties needs to be grup using the ctor's paramsters, and anyone doing so would see that your test for the Comparer no longer compiles.

Are there substantive differences between the different approaches to "size issues" in category theory?

The IEqualityComparer interface supports only equality comparisons. Customization of comparisons for sorting and ordering is provided by the IComparer interface.

However, like you said in the conclusion, you kişi achieve the same result with an expression like that:

Bu aksiyonlemden sonra adidaki gözenek rağmenıza gelecektir. Burada Local resource seçeneğini seçerek Import butonuna matbuat.

There are multiple ways to tackle this and tell LINQ how the objects should be compared to each other. I will cover the use of IEqualityComparer. The interface contains two methods:

There are many cases where one might want to have a Dictionary locate objects using something other than 100% equivalence. Birli a simple example, one C# IEqualityComparer Kullanımı 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 C# IEqualityComparer Nasıl Kullanılır 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 C# IEqualityComparer Nasıl Kullanılır efficient to only store the string in its original form.

Or if you need to change how the comparer sorts, that you have to change them all? Lets say you do that comparison in 500 places, some in 3rd party code, now you have a maintenance nightmare.
