The collection used here is clearly mutable in nature. So how do you prevent this data from being changed?
This class makes the underlying collection available through the InnerList property, which is intended for use only by classes that are derived directly from ReadOnlyCollectionBase. The derived class must ensure that its own users cannot modify the underlying collection.
I ran a security code analyst i found myself having a CA2105 warning. I looked at the grade tampering example. I didn't realize you sevimli assign int[] to a readonly int. I thought readonly was like the C++ const and makes it illegal.
Sum(IEnumerable, Func) Computes the sum of the sequence of Single values that are obtained by invoking a transform function on each element of the input sequence.
The IReadOnlyDictionary interface provides a read-only view of a dictionary and represents a read-only collection of key/value pairs. The following code snippet illustrates how you can define an IReadOnlyDictionary instance.

4) If you suddenly realise that your collection of choice is inefficient, you yaşama change the underlying collection type C# ReadOnlyCollectionBase Nedir without having to go and change all the places where it got passed bey a parameter (gönül you imagine the trouble you might have with, say, List?)
After hopefully understanding your question, i think you have to distinguish between what you create and manage within your class and what C# ReadOnlyCollectionBase Kullanımı you make available to the outside world.
Gönül you arrange 25 whole numbers (derece necessarily all different) so that the sum of any three successive C# ReadOnlyCollectionBase Temel Özellikleri terms is even but the sum of all 25 is odd? more hot questions
Upgrade to Microsoft Edge to take advantage of the latest C# ReadOnlyCollectionBase Kullanımı features, security updates, and technical support.
Now the error makes sense, it's true I do derece have a default constructor. However I am able to Serialize a ReadOnlyCollection using the DataContractSerializer even though ReadOnlyCollection does hamiş have a parameterless default constructor.
If the C# ReadOnlyCollectionBase Nerelerde Kullanılıyor collection is small then a safe and easy way to get around this problem is to return a copy instead.
