C# Main

First, when you create a new console application in the C# language using Visual Studio, you will get a Main method with a signature similar to the one shown here, ith a string[] args constant and abandoned acknowledgment type. You can use a Main adjustment that allotment an int or that receives no ambit if you wish to.

This program shows how the command-line parameters are received from a Windows command line and how you can access and test them in the C# program.

using System;

class Program
{
    static void Main(string[] args)
    {
        if (args == null)
        {
            Console.WriteLine("args is null"); // Check for null array
        }
        else
        {
            Console.Write("args length is ");
            Console.WriteLine(args.Length); // Write array length
            for (int i = 0; i < args.Length; i++) // Loop through array
            {
                string argument = args[i];
                Console.Write("args index ");
                Console.Write(i); // Write index
                Console.Write(" is [");
                Console.Write(argument); // Write string
                Console.WriteLine("]");
            }
        }
        Console.ReadLine();
    }
}
