[RESOLVED] How To Pass A Startup Parameter To A Windows C# Program

Anyone know how to pass a startup parameter to a program in C#.
I searched the net all over and the only thing I could find was for console applications. I also looked for overloads for the Form1_Load() and didnt find anything.

I would like to pass options to my program such as

program.exe /a
program.exe /b
program.exe /c
etc...

You pass them exactly has you have shown when starting the program. To read them within your app you would use the Environment.GetCommanLineArgs method.

Code:

---

string[] args = Environment.GetCommandLineArgs();

// The first commandline argument is always the executable path itself.
if (args.Length > 1)
{
    if (Array.IndexOf(args, "/a") != -1)
    {
        // The "/a" switch was used.
    }

    if (Array.IndexOf(args, "/b") != -1)
    {
        // The "/b" switch was used.
    }

    if (Array.IndexOf(args, "/c") != -1)
    {
        // The "/c" switch was used.
    }
}

If you start the program with the "Main" function instead of Form1_Load, you can get the command line args from there:

Code:

---

public string myProgramArgs;

static void Main(string[] args)
{
    myProgramArgs = args;
    Application.Run(new Form1);
}
