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 sevimli 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.

SingleOrDefault(IEnumerable, Func, TSource) Returns 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, 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
