How do destructors and garbage collection work in C#?
C# has finalizers (similar to destructors except that the runtime doesn't guarantee they'll be called), and they are specified as follows: class C{~C(){// your code}public static void Main() {}}Currently, they override object.Finalize(), which is called during the GC process.
Sarika Macha
- Apr 30th, 2011
Destructors implicitly calls Finalize() method. It is advised not to used Destructors because when GC runs it pushes the object which has destructor in FinalizeQueue and clears the object from memory ...

When do you absolutely have to declare a class as abstract ?
(as opposed to free-willed educated choice or decision based on UML diagram)? When at least one of the methods in the class is abstract. When the class itself is inherited from an abstract class, but not all base abstract methods have been over-ridden.

When you do not want to create an object of the class and want to provide some abstract implementation

All collections directly or indirectly should implement the ICollection interface or the ICollection(Of T) generic interface. If you check System.Array you will see ICollection interface in there. Correct answer is C, it doesn't matter that there are methods that can provide arrays of Names and Values. Because if you are reasoning like this, it means bject.ToString().ToCharArray() cause all classes are being collections.

X=x+1 is equivalent to x+=1 except that value of x is evaluated only once.x=x+1 is not equal to x++ (not always equal as mentioned in one of the earlier comments). If x++ is a standalone statement, the two have equal effect.
