c# How to run program using Command line argument [on hold]

Anonymous User 2470 04-Sep-2013

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.
