C# (Pronounced C Sharp) is a simple, Object Oriented Programming language. C# syntax is very much similar to C, C++ and Java.


// File name is —> Hello1.cs

using System;

public class Hello1
public static void Main()
Console.WriteLine(“Hello, World!”);

The Main method is the entry point of a C# console application or windows application. That is why Main must be static. Main can either have a void or int return type.


using System;

class TestClass


static void Main(string[] args)


// Display the number of command line arguments




Main method can be declared with or without a string[] parameter that contains command-line arguments.

There can only be one entry point in a C# program. If you have more than one class that has a Main method, you must compile your program with the /main compiler option to specify which Main method to use as the entry point.


/main : class
