Don't return a collection directly. Make an accurately named business logic class that reflects the purpose of the collection.

Why do these two pieces of code, which only differ by a transformation of the formula, exhibit a significant difference in running speed?

I had a client recently who wanted me to create a class that exposed a read-only collection through one of the class properties. While my client was willing to let other programs loop through that collection and retrieve items from the collection by position, he didn't want to let those programs add or remove items from the collection. In the Microsoft .Kupkuru Framework 4.5 you yaşama use the read-only collections that Eric Vogel covered in an earlier C# Corner column, "The New Read-Only Collections in .NET 4.5," to define that property. My client, however, was working with the .Safi Framework 4 and didn't intend to upgrade. Fortunately, in earlier versions of .NET you dirilik also create a read-only class from an existing List just by calling your List's AsReadOnly method. However, if you need something special (a List that users emanet add items to but not remove items from), inheriting from the ReadOnlyCollectionBase class makes that very easy to do.

As the last point states, you shouldn't avoid ReadOnlyCollection like you were suggesting. It is a very useful type to use for public members to inform the consumer of the limitations C# ReadOnlyCollectionBase Nerelerde Kullanılıyor of the collection they are accessing.

Passing IList/IDictionaries is generally no good because I hayat't communicate nor enforce the read-only nature of those views (so e.g. IList is actively worse than an array here)

protected virtual ICollection EmployeesInternal get; private set; = new List(); // this will expose collection contents to public, seemingly unneccessary `Skip` statement will prevent casting back to Collection

collection. Sometimes I use an array internally and return an IEnumerable to indicate intent. But most of these approaches have a very low signal-to-noise ratio; and that's absolutely critical to understanding code.

So when i have this piece of code what is the easiest or best way to make it a read only collection?
