IStructuralComparable arayüzü, çoğunlukla Array ve Tuple kabilinden done dokumaları aracılığıyla uygulanır. Bu muta mimariları, elemanlarının sıralamasını ve yapkaloriı dikkate alarak mukabillaştırma yapar.
Tip You birey loop over the ReadOnlyCollection using the foreach-loop. A for-loop is also possible with the Count property and indexer.
That method must return an Enumerator object, which provides the actual support for the looping through the collection. Similarly, code that retrieves an item by the item's position in the collection also looks for the IEnumerable interface and uses the GetEnumerator method. What the Enumerator object doesn't support are the Add or Remove methods. Ignoring the ReadOnlyCollectionBase
Which means that I always have to cast the items back to MyItem when I want to use them. Also the items dirilik be casted into MyItem outside the class.
Bu sayede, done yapılarının kucakindeki verilerin sıralanması yahut karşılaştırılması işlemleri özelleştirilebilir ve yoklama edilebilir hale hasılat.
You dirilik expose private collection properties to EF, allowing for mapping and querying, while still keeping your domain object's members and relationships properly encapsulated. It's a bit messy, but it works:
Ancestors(IEnumerable) Returns a collection of elements that contains the ancestors of every node in the source collection.
An immutable object is defined as an object that C# ReadOnlyCollectionBase Kullanımı cannot be changed after it saf been created. Derece all collections are immutable, but you emanet use the read-only collection types in .
C# IStructuralEquatable arabirimini uygulayıcı C# ReadOnlyCollectionBase Kullanımı bir C# ReadOnlyCollectionBase Temel Özellikleri özel koleksiyon klası oluşturarak, nasıl strüktürel eşitlik kontrolörü konstrüksiyonlacağını anlamak önemlidir. Hordaki örnek, bu mevzuyu daha yararlı anlamanıza yardımcı olacaktır:
In Visual Basic, an extension method must be declared inside a Module and decorated with the Extension attribute. Its first parameter specifies the kind of object to which it will attach itself. I want my extension method to appear in the IntelliSense dropdown lists for any class that implements the IList interface, so I'll declare the method's first (and only) parameter bey IList(of T) -- the compiler will figure out the type that T represents based on the List passed to my method.
However, the syntax is awkward. Adding an extension method güç simplify 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 C# ReadOnlyCollectionBase Nerelerde Kullanılıyor called from birli 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.

Average(IEnumerable, Func) Computes the C# ReadOnlyCollectionBase Nasıl Kullanılır average of a sequence of nullable Single values that are obtained by invoking a transform function on each element of the input sequence.
