Main method in c#

string[] args is used to read the console parameter for the application.

For example, you're creating application, which needs to accepts the startup / console parameters then use call the application something like ,

consoleApplication.exe /name:murali /Site:www.c-sharpcorner.com

These values will be passed into the application using , string[] args parameter. It is not necessary to use the args when there is no startup / console parameter for an application.

using System;

class Hello
{
    // static Main no return, arguments
    public static void Main(string[] args)
    {
        for (int i = 0; i < args.Length; i++)
        {
            Console.Write("Args {0}, {1}", i, args[i]);
            Console.Write("\n");
        }
    }
}

Hope this helps you.
