Interview Questions - C#.NET

Hi,

If you read my blogs from initial stage, you could have realised one thing. I have started posting series of interview questions in December2006; but I could not continue it. Extremely sorry for it. I will try to post some more questions in the near future.

Here, I will start with C#.NET.

1) What is the difference between a Struct and a Class?
Ans: Structs are value-type variables and are thus saved on the stack, has faster retrieval over other. Structs can not inherit.

2) Can we inherit multiple interfaces?
Ans: Yes, we can.

3) Can we allow a class to be inherited, but prevent a method from being over-ridden?
Ans: We can make class as "public" and leave the method as "Sealed".

4) Will finally block get executed if an exception has not occured?
Ans: Yes.

5) Can we store multiple data types in System.Array?
Ans: No, we can not.

C U soon with some more questions...

Happy coding....!!!!
