Compiling A C# Program

The basic definition of C#

It’s an elegant and type-safe object-oriented language that enables us to build a variety of applications which include Windows applications, XML Web Services, Distributed Components, client-server applications, and much more.

It enables us to build a secure and robust application.

Derivation of C-sharp language

In C#, the # represents the musical notation, The C# language has a similar syntax as C and C++. It’s a multi-paradigm programming language. It’s also an object-oriented programming language like Java. It has the power to develop software. C# has redefined the programming landscape. It has numerous applications in various fields. The most recent form of the C# language is 7.2 which was released in 2017 along with Visual Studio 2017.

Similarity of C-sharp with other languages

It’s also an object-oriented programming language. It’s derived from C and C++ languages.

Both Java and C# generate an intermediate language ( i.e., after compilation it generates an intermediate language).

C# generates an MSL and Java generates the Java bytecode.

Differences between C# with other languages

Java doesn’t support operator overloading while C# supports operator overloading. C# uses CLR and java uses Java Virtual Machine. Java does not support delegates, while C# uses delegates, which are type-safe method pointers. These are used to implement event-handling.

Application

Software developed in C# language includes: Pinta (a bitmap image drawing and editing program), Visual Studio (which is written in both C# and C++) and Open Dental (Practice management software).

Nowaday’ most developers use the C# language.

Compiling a C# program

In this article, we will learn how to compile a C# program using command prompt for the below code.

using System;
namespace navi {
    Class Program {
        Public static void Main(string[] args) {
            Console.WriteLine("Hello World");
            Console.ReadLine();
        }
    }
}

Save the file with extension .cs (c-sharp).For example, in this, I save my C# file as navi.cs.

Code explananation

In this file, I will  explain my code:

• using System
  The first line using used to work with the C# object and implement with I Disposable interface
  
  
• namespace cs
  The namespace is used to provide a "named space" in which your application resides. Without namespace, we cannot use Console.
  
  
• class Program
  A class is a construct which enables us to create our own custom types by grouping together variables of other types, methods, and events.
  
  
• Console.WriteLine()
  It's used to display the output to the user. For displaying the strings we must use that inside the double quotes.
  
  
• Console.ReadLine()
  It's used to get the input from the user.

For Windows 10

• Type Developer Command Prompt in the windows search bar and  a console window appears
  
  
  
  
• In the console window navigate to the file location.
  
  
• Then simply use the file name for execution.
