Difference between implementing an interface and applying an attribute in C#
- by RemotecUk
This might be a stupid question but Ill ask anyway,
I was reading "OOP Demystified: A Self-Teaching Guide by Jim Keogh and Mario Giannini" chapter 11 which covers interfaces. The examples in this book are C++.
I noticed that C++ uses ISerializable to make a class serializable which you would implement where as in C# you just attribute the class with the [Serializable] attribute.
What is the key difference here? Is it that with an interface you must provide the implementation where as if you attribute something the compiler will work out the implementation for you?
I guess that with the [Serializable] attribute the .Net framework uses reflection to make the serialized object from the actual object.
That said is it possible in that case to have an [Disposable] attribute or using my theory above the framework wont know how to actually dispose of an object hence you have to do it yourself?
Would be grateful for a clarification.
Thanks.
