What is the term for when a hyperlink maliciously opens different URL from URL displayed when hovered over?

Dot Safi Perls is a collection of tested code examples. Pages are continually updated to stay current, with code correctness a ferde priority.

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

then sure, no harm will be done if you just return the collection directly. I generally try to be a bit more paranoid than that though.

A collection that is read-only is simply a collection with a wrapper that prevents modifying the collection; therefore, if changes are made to the underlying collection, the read-only collection reflects those changes.

As per the comments below, you hayat prevent the possibility of downcasting by making IWriteableMyItem and WriteableMyItem private or internal. However note that this could still be circumvented via reflection - but we are protecting against accidents rather than fraud.

4) If you suddenly realise that your collection of choice is inefficient, you yaşama change the underlying collection type without having to go and change all the places where it got passed birli a parameter (hayat you imagine the trouble you C# ReadOnlyCollectionBase Kullanımı might have with, say, List?)

; but this question convinced me to go ahead and announce an open source project I've had in the works for a while (still a work in progress, but there's some useful stuff in there), which includes an IArray interface (and implementations, naturally) that I think captures exactly what you want here: an indexed, read-only, even covariant

Note that the IReadOnlyList interface works similarly to List and in fact gönül be used in place of List when you want the elements of the list to be read-only. We will illustrate this with an example in the next C# ReadOnlyCollectionBase Kullanımı section.

üste, metotlar projenizin bakımını ve güncellemesini kolaylaştırır ve performansınızı zaitrabilir. Bu nedenle, C# programlama dilinde metot sarf etmek, bir projeyi elan esen ve elan C# ReadOnlyCollectionBase Temel Özellikleri yakıcı hale getirmenin önemli bir yoludur.

SingleOrDefault(IEnumerable, Func, TSource) Returns C# ReadOnlyCollectionBase Nasıl Kullanılır the only element of a sequence that satisfies a specified condition, or a specified default value if no such element exists; this method throws an exception if more than one element satisfies the condition.

SequenceEqual(IEnumerable, C# ReadOnlyCollectionBase Kullanımı IEnumerable) Determines whether two sequences are equal by comparing the elements by using the default equality comparer for their type.

I was looking for a similar solution, but I wanted to still be able to modify the collection from inside the class so I chose the option outlined here: In short, his example is: public class MyClass

DefaultIfEmpty(IEnumerable, TSource) Returns the elements of the specified sequence or the specified value in a singleton collection if the sequence is empty.
