What does new Class(i) in C# mean?

13 Oct 2015 by OriginalGriff

When you create a "blank" class, it is given a default constructor by the compiler - one which takes no parameters. It's as if you wrote the class as:public class MyClass { public MyClass() {} }But a default constructor isn't the only one you can have - you can have constructors...

It creates an instance of class "Class", which is possible due to "Class" not being the keyword "class". It will be defined somewhere else in the code you're looking at. The constructor for Class takes an argument whose type i is compatible to. The Class constructor then does something with i...

No and you shouldnt do it, because it destroyes the class pattern of encapsulation. If you need to modify a class object it should always made with member functions.I think you must rethink your software design. Learn from this tutorials.

Largely because you spelled everything differently. You used Salarie for your class, Sailary for the constructor, and sailary when trying to instantiate an object. You also spelled other bits wrong in your show method. A bit more care in typing would go a long way.
