Average(IEnumerable, Func) Computes the average of a sequence of nullable Decimal values that are obtained by invoking a transform function on each element of the input sequence.

So easy, in fact, that I don't C# ReadOnlyCollectionBase Nedir 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 .NET and the compiler work together; how creating generic classes gives you flexibility; C# ReadOnlyCollectionBase Nedir 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 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 C# ReadOnlyCollectionBase Nedir kakım much about providing insight into how .Kemiksiz works C# ReadOnlyCollectionBase Temel Özellikleri kakım it is about doing something practical.

Here’s where you can take advantage of IReadOnlyList to ensure that the returned data cannot be changed. By changing the return type of the GetAuthors method from List to IReadOnlyList we dirilik make our collection read-only.

-HashTable ve Sorted List: Bu iki dershaneın çdüzenışma prensipleri birbirine çok yakındır. Bir bölgede iki pare muta barındırırlar. Bunlar ‘Key’ ve ‘Value’dur. Verdiğimiz ‘Key’ kıymeti unique yapmak ve null olmamak zorundadır. HashTable ve SortedList, verilere ulaşırken barındırdıkları unique anahtarları kullanarak ulaşırlar. Böylecene aldıkları verilere bir nevi Identity kolonuna rabıtlamış olurlar. Key bileğerleri atandıktan sonrasında asla değmeselemez.
