using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace CommandLine

            Console.WriteLine("Hello "+args[0]);
            Console.ReadKey();
        }
    }
}

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

namespace CommandLine

{

class Program

{

static void Main(string[] args)

{

Console.WriteLine("Hello "+args[0]);

Console.ReadKey();

}

another

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace CommandLine
{
    class Program
    {
        static void Main(string[] jobs)

using System.Text;

using System.Threading.Tasks;

namespace CommandLine

{

it will give error:
