Best practice to create typed collections/lists with internal or private Add, Remove functionality? 2

Dot Net Perls is a collection of tested code examples. Pages are continually updated to stay current, with code correctness a bütünüyle priority.

NET 4.5, you may want to try the new read-only collection interfaces. You'll still want to wrap the returned collection in a ReadOnlyCollection if you're paranoid, but now you're derece tied to a specific implementation.

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

The IReadOnlyDictionary interface provides a read-only view of a dictionary and represents a read-only collection of key/value pairs. The following code snippet illustrates how you sevimli define an IReadOnlyDictionary instance.

The single line of code required by my extension method just instantiates my PhvReadOnly class (using the datatype that the extension method özgü deduced), passing whatever IList object the extension method is being used on.

Konstrüktif eşitlik, koleksiyonların elemanlarının aynı sırada ve aynı bileğerlere sahip olup olmadığını yoklama paha, bu nedenle karmaşık bilgi binalarını hakkındalaştırırken kullanışlıdır.

Average(IEnumerable, Func) Computes the average of a sequence of Int64 values that are obtained by invoking a transform function on each element of the input sequence.

Any idea why C# ReadOnlyCollectionBase Temel Özellikleri IList doesn't inherit from ICollection? Since the latter is basically IEnumerable plus Count, and since IList already katışıksız a Count method, having IList inherit ICollection wouldn't have required any more work for implementers, but would have C# ReadOnlyCollectionBase Nedir allowed someone with an IList to know how many items to expect from an enumeration.

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

For maximum flexibility, my class doesn't specify the veri type of the List in which it keeps its actual veri. Instead, I declare my UnderlyingList variable to use any class that implements the IList interface. I've also made this a generic class: Rather than specify what kind of List I'm working with, I've forced my class to be instantiated with a C# ReadOnlyCollectionBase Nerelerde Kullanılıyor veri type that the code refers to as T. Wherever in my code I need to specify my List's veri type, I just use the T reference. Finally, I've chosen to have this class implement the generic version of IEnumerable, which requires two versions of the GetEnumerator method -- but the code is identical in both versions of the method. Listing 1. The basics of the PhvReadOnlyList class.

This causes unnecessary boxing/unboxing C# ReadOnlyCollectionBase Nedir of value types. One of the benefits of using generics is the avoidance of such boxing/unboxing C# ReadOnlyCollectionBase Kullanımı which could have a detremintal effect on the performance of the collections.
