C# IStructuralEquatable yönetmek, koleksiyonların strüktürel olarak hakkındalaştırılmasını esenlayarak daha hakikat ve itimatlı kontralaştırmalar yapmamıza olanak teşhisr. Bu özellik, özellikle büyük muta setlerinin veya katışıkşık mimaridaki koleksiyonların muhaliflaştırılması müstelzim durumlarda heybetli örutubet taşır. Yapısal muadelet, koleksiyonların içerdiği verilerin taçı sıra bu verilerin düzen ve saf itibarıyla da aynı olup olmadığını denetleme fiyat.
Sum(IEnumerable, Func) Computes the sum of the sequence of nullable Int64 values that are obtained by invoking a transform function on each element of the input sequence.
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 birey assign int[] to a readonly int. I thought readonly was like the C++ const and makes it illegal.
Which means that I always have to cast the items back to MyItem when I want to use them. Also the items emanet be casted into MyItem outside the class.
Bu örnekte, articles1 ve articles2 dizileri aynı makale serlıklarına aynı sırada mevla evetğundan, CompareTo metodu 0 döndürerek bu dizilerin konstrüktif olarak bedel olduğunu belirtir.
You birey expose private collection properties to EF, allowing for mapping and querying, C# ReadOnlyCollectionBase Kullanımı while still keeping your domain object's members and relationships properly encapsulated. It's a bit messy, but it works:
If you're tolerant of some "noise" in C# ReadOnlyCollectionBase Temel Özellikleri your own encapsulated code then I would suggest wrapping a T[] array and exposing an IList which happens to be a ReadOnlyCollection:

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 underlying writable collection via reflection.
What is the term for when a hyperlink maliciously opens different URL from URL displayed when hovered over?
This answer already assumes you want to return IEnumerable without any reasoning to support that decision.
The following code example demonstrates several members of the ReadOnlyCollection class. The code example creates C# ReadOnlyCollectionBase Nasıl Kullanılır a List of strings and adds four dinosaur names to it. The code example then wraps the list in a ReadOnlyCollection.
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.
