A) Making class as AbstractB) Having a Private constructorC) Making the class sealedD) Both A & B

Naveen Kumar Shivanadri

• Sep 8th, 2016

Answer is A is always correct and B is also correct only the situation when the class does not have the static methods on it (in the question, there is no mentioned that there is no static method in it)
So, only A is correct answer.

Yes, there can be a static constructor. It will be at class level & executed just once. It is totally in run-times control & not sure of when this will be executed. But, it is assured that it will be executed before creating instance of the class.

Both B & C are wrong. Interfaces can be private and in that case public classes cannot inherit them. You can define it within a class. C is wrong as we cannot create an instance of the interface.

Two objects that are equal return hash codes that are equal. However, the reverse is not true: equal hash codes do not imply object equality, because different (unequal) objects can have identical hash codes

Application domains are typically created by runtime host( i.e. Windows process/program). Application domains provide an isolation boundary for security,.... .NET program is an Assembly loading into an Application domain. Threads are the operating system construct used by the common language runtime to execute code in Application domains. Therefore, for .NET, Process (runtime host) -> Application Domains -> Assemblies (.NET programs)-> Managed Threads.

Keyword sealed can be used with class declaration to prevent it from being sub-classed.
Keyword sealed can be used in method declaration to prevent it from being overridden.

To restrict users from inheriting the class by sealing the class using "sealed" keyword i.e. no class can be drieved from a sealed class. both Class and Method can be sealed, in that case Method cannot be overridden.
