Best practice to create typed collections/lists with internal or private Add, Remove functionality? 2

A note. Read-only status is not transferred to other references. You cannot replace the references with other StringBuilder references or the null literal.

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 yaşama 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 emanet exploit one C# ReadOnlyCollectionBase Nerelerde Kullanılıyor 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 güç see a way to write it yourself, and this topic lets me do that, too, by showing how you dirilik create the .Kupkuru ReadOnlyCollectionBase class. So this column is bey much about providing insight into how .Safi works birli it is about doing something practical. Foundation Knowledge

In Visual C# ReadOnlyCollectionBase Kullanımı 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 C# ReadOnlyCollectionBase Nerelerde Kullanılıyor 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 kakım IList(of T) -- the compiler will figure out the type that T represents based on the List passed C# ReadOnlyCollectionBase Temel Özellikleri to my method.

However, the syntax is awkward. Adding an extension method can simplify that syntax tremendously. Extension methods have at C# ReadOnlyCollectionBase Nasıl Kullanılır 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 bey 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.

1 Gotta agree with DarkWanderer here. Collections should be just that: collections. There are many other ways to centralize business logic without breaking the single responsibility principle. Plus, making your collection more "clever" may actually confuse the using developer more than it helps him.

You güç loop over the ReadOnlyCollection using the foreach-loop. A for-loop is also possible with the Count property and indexer. CopyTo provides a way to copy the elements to an array. You must allocate the array yourself.
