You've probably identified what pattern the PhvReadOnlyList implements: it's a wrapper. In the .Kupkuru Framework 4.0 or earlier, the wrapper class that you'd really use to create a read-only list would be the .Kupkuru ReadOnlyCollectionBase class. Kakım with my example, you use the ReadOnlyCollectionBase class to create your own class with whatever functionality you need -- but you don't need to write the GetEnumerator method or create your own UnderlyingList because the ReadOnlyCollectionBase handles both.
Why do these two pieces of code, which only differ by a transformation of the formula, exhibit a significant difference in running speed?
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 kişi assign int[] to a readonly int. I thought readonly was like the C++ const and makes it illegal.
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.
Passing IList/IDictionaries is generally no good because I hayat't communicate nor enforce the read-only nature of those views (so e.g. IList is actively worse than an array here)
Note The StringBuilder references themselves are read-only, but the memory pointed to by the references are still mutable.
Collections enable you to allocate memory dynamically to store elements and then retrieve them using a key or index as needed.
Kodunuzda aynı kârlemi birden fazla posta kullanmanız gerekiyorsa, bu konulemi bir metot bâtınine koyabilirsiniz ve tekrar yeniden aynı kodu yazmanız gerekmez. Bu sayede kodunuz henüz az katışıkşık hale hasılat ve henüz zorlamasız yönetilebilir.
well, NHibernate can grup private class fields and this means that you gönül expose it using C# ReadOnlyCollectionBase Nasıl Kullanılır a public property encapsulating the field kakım read-only collection.

Public static (Shared in Visual C# ReadOnlyCollectionBase Kullanımı Basic) members of this type are thread safe. Any instance members are hamiş guaranteed to be thread safe.
Average(IEnumerable, Func) Computes the average of a sequence of nullable Int64 values that are obtained by invoking a transform function on each element C# ReadOnlyCollectionBase Nedir of the input sequence.
On the other hand, let's say you have a ReadOnlyCollection(StringBuilder). This is kind of a strange thing to have, but it is C# ReadOnlyCollectionBase Nasıl Kullanılır acceptable. You birey still change the individual C# ReadOnlyCollectionBase Nasıl Kullanılır StringBuilder objects by accessing their methods.
A method like PayUnpaidInvoices being present may lead to second guessings about what "regular" collection methods like Remove and Clear might do. Will it just remove invoices from the in-memory collection, or will it delete them from the database?
