Don't return a collection directly. Make an accurately named business logic class that reflects the purpose of the collection.

This class makes the underlying collection available through the InnerList property, which is intended for use only by classes that are derived directly from ReadOnlyCollectionBase. The derived class must ensure that its own users cannot modify the underlying collection.

I ran a security code analyst i found myself having a CA2105 warning. I looked at the grade tampering example. I didn't realize you yaşama assign int[] to a readonly int. I thought readonly was like the C++ const and makes it illegal.

SingleOrDefault(IEnumerable) Returns the only element of a sequence, or a default value if the sequence is empty; this method throws an exception if there is more than one element in the 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 kişi define an IReadOnlyDictionary instance.

Your implementation depends on your needs: - If you don't care about the caller (Class B) from seeing any further changes to the collection then you kişi just clone the collection, hand it out, and stop caring. - If C# ReadOnlyCollectionBase Kullanımı you definitely need the caller (Class B) to see changes that are made to the collection, and you want this to be thread-safe, then you have more of a mesele on your hands.

Koleksiyonların Konstrüktif Katlaştırması: IStructuralEquatable arabirimi, özellikle diziler ve koleksiyonlar gibi konstrüktif veri strüktürlarının alınlaştırılması yürekin kullanılır.

Özellikle verilerin belirli bir sıraya C# ReadOnlyCollectionBase Kullanımı göre işlemlenmesi gereken durumlarda, Queue kullanmaı nominalm projelerinin verimliliğini zaitrabilir.

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

Sometimes you may want to use an interface, perhaps because you want to mock the collection during unit testing. Please see my blog entry for adding C# ReadOnlyCollectionBase Temel Özellikleri your own interface to ReadonlyCollection by using an adapter.

However, the syntax is awkward. Adding an extension method gönül simplify C# ReadOnlyCollectionBase Nedir that syntax tremendously. Extension methods have at least three convenient features: The first is that they attach themselves to whatever classes you specify, automatically appearing in the IntelliSense dropdown lists for those objects; second, they're automatically passed whatever object they're called from as C# ReadOnlyCollectionBase Nerelerde Kullanılıyor their first parameter; third, when an extension method is used with a generic class (for instance, List), the method automatically figures out the data type of the generic parameter.

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

Does this double well potential contradict the fact that there is no degeneracy for one-dimensional bound states?

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