Newbie in C# Using Agruments

[Iron Skull]

Hi I need to call my Program like this:
C:\program.exe name

And I want to show the Agrument name in a label.
I tryed to do this like this:

namespace HelloWorld
{
    public partial class frmMain : Form
    {
        public frmMain()
        {
            InitializeComponent();
        }

        private void frmMain_Load(object sender, EventArgs e)
        {
            lblMsg.Text = "Hello" + e + "to this world!";
        }
    }
}

I figured out that this was wrong..
I didn't find anything on google.
And I asked my C# Teacher.. And she had NO CLUE were I was talking about..

(Ok, she is really a noob, she only knows or textbook inside - out but ok..)

Is here ayone how can help me out ^^?

The command-line arguments are not sent to any events, they are sent to the static Main() procedure of your startup class, if you define one that has a string[] argument.

class MyProgram
{
  [STAThread] static void Main(string[] args)
  {
    // ...
  }
}

You can also access them using the static Environment.GetCommandLineArgs() method.

lblMsg.Text = "Hello" + string.Join(", ", Environment.GetCommandLineArgs()) + "to this world!";

So in Program.cs I need to change:

        static void Main()
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new frmMain());
        }

into

        static void Main(string[] args)
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new frmMain());
        }

this

And then I need to send the var args to my Form1.cs?

Thanks ^^

Yeah you can do that by passing them to the frmMain constructor or you can use Environment.CommandLine like I showed in my second example. Whichever way you choose is up to you.
