How to run a program using command line argument for example my program only runs when i say a string e.g Hello World if this value does not match then it should give an error.

if (args == null)

{

    Console.WriteLine("cant be null"); // Check for null array

}

if (args[0].Contains("Hello World"))

{

    Console.WriteLine("True"); // Check for null array

}

else

{

    Console.WriteLine("Error"); // Check for null array

}

Thanks in advance.

    Hi Ankita,


    Write this code in your main method(I am considering you are doing this in a Console application);

            if(args.Length <= 0)
            {
                //Error
            }
            else if(args.Length >= 1)
            {
                if(args[0] == @"Your argument")
                {
                    //No error.
                }
                else
                {
                    //Error
                }
            }

    Hope this helps you.
