A "Hello, World!"program is usually a simple computer program that emits displays to the screen (often the console) a message similar to "Hello, World!".A small piece of code in most general-purpose programming languages, this program is used to illustrate a language's basic syntax.
C# (/ ˌ s iː ˈ ʃ ɑːr p / see SHARP) [b] is a general-purpose high-level programming language supporting multiple paradigms.C# encompasses static typing, [16]: 4 strong typing, lexically scoped, imperative, declarative, functional, generic, [16]: 22 object-oriented (class-based), and component-oriented programming disciplines.

Whether it is a console or a graphical interface application, the program must have an entry point of some sort. The entry point of a C# application is the Main method. There can only be one declaration of this method, and it is a static method in a class. It usually returns void and is passed command-line arguments as an array of strings.
[6]: 67 Candidates answering questions should consider the use of technology in the present and future, and user scenarios. Some questions involve projects that the candidate has worked on in the past. A coding interview is intended to seek out creative thinkers and those who can adapt their solutions to rapidly changing and dynamic scenarios.
The XAML file declaratively defines the layout, contents and other properties of the UI element, while the C# file allows exposure of code entry points for interactivity. [4] A basic example of an interactive Hello, World! program could be created like so: MainWindow.xaml:
String functions are used in computer programming languages to manipulate a string or query information about a string (some do both).. Most programming languages that have a string datatype will have some string functions although there may be other low-level ways within each language to handle strings directly.
