My code is littered with collections - hamiş an unusual thing, I suppose. However, usage of the various collection types isn't obvious nor trivial. Generally, I'd like to use the type that's exposes the "best" API, and özgü the least syntactic noise.

dictionaries). Kakım it turns out, many lists are never changed, or at least never extended. Of course ReadOnlyCollection introduces yet more syntactic noise, and it doesn't even convey quite what I mean; after all ReadOnlyCollection may wrap a mutating

That method must return an Enumerator object, which provides the actual support for the looping through the collection. Similarly, code that retrieves an item by the item's position in the collection also looks for the IEnumerable interface and uses the GetEnumerator method. What the Enumerator object doesn't support are the Add or Remove methods. Ignoring the ReadOnlyCollectionBase

Sum(IEnumerable, Func) Computes the sum of the sequence of Decimal values that are obtained by invoking a transform function on each element of the input sequence.

Sum(IEnumerable, Func) Computes the sum of the sequence of Double values that are obtained by invoking a transform function on each element of the input sequence.

Also, native collections can't be enhanced with extra data. You'll recognize this next time you find that you pass in (Collection, Extra) to more than one or two methods. It indicates that "Extra" belongs with the object containing your collection.

1. The reason for derece choosing ReadOnlyCollectionBase is simple - it isn't generic, while the aim of ReadOnlyCollection is to be generic. Thus it needs a much different inheritance tree.

Fakat, articles1 ve articles3 dizileri aynı makale esaslıklarına farklı sıralarda iye olduğundan, CompareTo metodu farklı bir paha döndürür ve bu dizilerin yapısal olarak müsavi olmadığını belirtir.

Kişi you arrange 25 C# ReadOnlyCollectionBase Kullanımı whole numbers (not necessarily all different) so that the sum of any three successive terms is even but the sum of all 25 is odd? more hot questions

If you do this then there's nothing stopping your callers casting the IEnumerable back to ICollection and then modifying it. ReadOnlyCollection removes this possibility, although it's still possible to access the C# ReadOnlyCollectionBase Temel Özellikleri underlying writable collection via reflection.

Nothing wrong with wordy types for major API's with small surfaces, but hamiş birli a general practice inside a large codebase.

This base class is provided C# ReadOnlyCollectionBase Nasıl Kullanılır to make it easier for implementers to create a strongly C# ReadOnlyCollectionBase Temel Özellikleri typed read-only custom collection.

SkipWhile(IEnumerable, Func) Bypasses elements in a sequence kakım long birli a specified condition is true and then returns the remaining elements. The element's index is used in the logic of the predicate function.
