- 5. Which of the following statements are correct about Attributes used in C#.NET?
Options- A. If there is a custom attribute BugFixAttribute then the compiler will look ONLY for the BugFix attribute in the code that uses this attribute.
- B. To create a custom attribute we need to create a custom attribute structure and derive it from System.Attribute.

Inheritance problems
Search Results
Correct Answer: True
Explanation:
This is because the member functions are always searched in the derived class and then in the base class.
Correct Answer: Classes and Methods
Correct Answer: 4, 5
Correct Answer: [ assembly : AssemblyDescription("DCube Component Library") ]
Correct Answer: The CLR can change the behaviour of the code depending upon the attributes applied to it.
Correct Answer: True
Correct Answer: True
Correct Answer: True
Explanation:
Multiple inheritance means deriving a class from more than one classes. On the other hand, multiple levels of inheritance means a class has been derived from a base class and the base class itself has been derived from another base class. Multiple inheritance is not permitted in C#.NET.
Correct Answer: True
Explanation:
We can derive from a base class even if it is present in an assembly.
Correct Answer: False
Explanation:
Base class cannot access derived class members since it does not have any knowledge of the derived class.
