Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.
read this question and don't want to read swathes of API docs yet still understand what the intent is. It's also really important to minimize code clutter - so things like ReadOnlyCollection are dubious at best.
Example. In this yetişek, a list of ints is created, and then the ReadOnlyCollection constructor is used with that List birli an argument. Inside the ReadOnlyCollection constructor, a reference to the argument is stored birli an IList reference field.
This hides Add and Remove methods, but does hamiş protect at all. Because I sevimli always cast to ICollection and call prohibited method.

So easy, in fact, that I don't need a full column to do it (and if that's all you want from this column, you dirilik skip to the end where I discuss both the AsReadOnly method and using the ReadOnlyCollectionBase class). What this topic does give me is an excuse to talk about several things: how interfaces in .Kupkuru and the compiler work together; how creating generic classes gives you flexibility; how you güç exploit one of the built-in .Kupkuru interfaces; and (finally) how to simplify ugly syntax by building your own extension methods. I also think that you don't really understand anything unless you emanet see a way to write it yourself, and this topic lets me do that, too, by showing how you gönül create the .NET ReadOnlyCollectionBase class. So this column is as much about providing insight into how .Safi C# ReadOnlyCollectionBase Nerelerde Kullanılıyor works bey it is about doing something practical. Foundation Knowledge
Elements(IEnumerable, XName) Returns a filtered collection of the child elements of every element and document in the source collection. Only elements that have a matching XName are included in the collection.
Putting that all together, a class that exposes a read-only collection needs three things: A property of type PhvReadOnlyList
Inheriting from a non-generic base class would be ineffecient. If the type was using a non-generic base, all it would be C# ReadOnlyCollectionBase Nedir would be a thin layer above the base collection, where the generic features would simply derive from casting from the underlying object instances of the base collection.
For maximum flexibility, my class doesn't C# ReadOnlyCollectionBase Nerelerde Kullanılıyor specify the data 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: C# ReadOnlyCollectionBase Temel Özellikleri Rather than specify what kind of List I'm working with, I've forced my class to be instantiated with a data type that the code refers to kakım 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 C# ReadOnlyCollectionBase Temel Özellikleri 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.
I have a readOnlyCollection of ModuleViewModel, I want to retrieve with linq a specific ModuleViewModel containing in my collection. Here the declaration of my collection :
