Bu muamelat yetişekın henüz yavaş çaldatmaışmasına ve tipin objeye devirmesinden dolayı bellekte daha şu denli arsa tutmasına münasebet olur. Nedeniyle ne derece az boxing eşittir o kadar bereketli program.

Define your own class which implements IEnumerator, takes an IList in the new constructor, başmaklık a read only default item property taking an index, and does hamiş include any properties/methods that could otherwise allow your list to me manipulated.

1 Birli long birli WritableMyItem is made private, bey @KlausGütter suggested, this solution seems to work great. The other mesele I thought I would face is if the IReadOnlyList is casted into a IList, but since IList's type parameter is hamiş covariant, I don't think this is possible. Thank you!

List's are a very common datastructure, but creating them in this fashion involves quite a bit of syntactic noise - and it hayat easily get even worse (e.g.

Sum(IEnumerable, Func) Computes the sum of the sequence of Int32 values that are obtained by invoking a transform function on each element of the input sequence.

Note The StringBuilder references themselves are read-only, but the memory pointed to by the references are still mutable.

What's the best way to pass around lists of values without lots of code clutter (such bey explicit type parameters) but that still communicates C# ReadOnlyCollectionBase Temel Özellikleri intent clearly?

Özellikle verilerin sınırlı bir sıraya için aksiyonlenmesi müstelzim durumlarda, Queue kullanmaı nominalm projelerinin verimliliğini artırabilir.

SkipLast(IEnumerable, Int32) Returns a new enumerable collection that contains the elements from source with the last count elements of the source collection omitted.

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

SingleOrDefault(IEnumerable, Func, TSource) Returns the only element of a sequence that satisfies C# ReadOnlyCollectionBase Nedir a specified condition, or a specified default value if no such element exists; this method throws an exception if more than one element satisfies the condition.

However, to be doubly sure, I'd like to return the collection as read-only, so that the calling code is unable to make changes to the collection, only view C# ReadOnlyCollectionBase Temel Özellikleri what's already there. Is this at all possible?

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

If however your intent is to prevent the calling code from observing updates from other threads you'll have to fall back to solutions already mentioned, to perform a deep or shallow copy depending on your need.
