No. C# cannot use printf, cout or consol.writeline. printf and cout are C/C++ functions. C# would use Console.WriteLine as you have to spell it correctly and it's case sensitive. As for the rest of your "question" why don't you simply try it and find out for yourself?

You can, but you should not do it. Constructors should do the minimum amount of work necessary to initialise the object.

That's confused, because C doesn't have constructors, so printf is irrelevant.
C++ and C# both have object constructors, and you can happily call the appropriate text output methods in constructors with either language: cout for C++, and Console.WriteLine or Debug.WriteLine for C#.

Do note that unless you are developing a Console based application, you don;t have a "text display" that the user can automatically see - so these methods are of very limited use in modern applications where UI elements such as text boxes and labels are more normally used to communicate with the user.
