Don't return a collection directly. Make an accurately named business logic class that reflects the purpose of the collection.
An instance of the ReadOnlyCollection generic class is always read-only. 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. See Collection for a modifiable version of this class.
1 Kakım long birli WritableMyItem is made private, birli @KlausGütter suggested, this solution seems to work great. The other mesele I thought I would face is if the IReadOnlyList is casted into a IList, but since IList's type parameter is derece covariant, I don't think this is possible. Thank you!

Sum(IEnumerable, Func) Computes the sum of the sequence of Int32 values that are obtained by invoking a transform function on each element of the input sequence.
You want to use the yield keyword. You loop through the IEnumerable list C# ReadOnlyCollectionBase Kullanımı and return the results with yeild. This allows the consumer to use the for each without modifying the collection.

However, the syntax is awkward. Adding an extension method gönül simplify that syntax tremendously. Extension methods have at 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 C# ReadOnlyCollectionBase Temel Özellikleri called from kakım their first parameter; third, when an extension method is used with a generic class (for instance, List), the method automatically figures out the veri type of the generic parameter.
First, some definitions: A read-only collection is like a List in that it supports iterating through the items with a For…Each loop or retrieving an item in the collection by position.
