oh.....that is a good fix. :=) cool.

This works really well. I had to make one small change though to get
it to work with my non-single-character arguments.
ApplicationCommandLine.cs, Ln 142 -
Change to: string argValue = args[count];
Thanks for the help!

There are 3 classes that might help you
ApplicationCommandLine.cs
CommandlineArgument.cs
CommandlineException.cs
To use them do something like this:
First build an array of acceptable commandline arguements, such as ...
ApplicationCommandLine _cmdProcessor = new ApplicationCommandLine();
// create the help argument
_cmdProcessor.AddArg(new CommandLineArgument("?", "prints help"));
// create the toggled argument of erase only or overwrite file options
SwitchableCommandLineArgument eraseOnly = new
SwitchableCommandLineArgument("e", "only erases the file,
content IS NOT overwritten first");
SwitchableCommandLineArgument overwriteFile = new
SwitchableCommandLineArgument("w", "overwrites the file
prior to erasing [default]");
eraseOnly.SwitchArg = overwriteFile;
overwriteFile.SwitchArg = eraseOnly;
overwriteFile.Selected = true;
_cmdProcessor.AddArg(eraseOnly);
_cmdProcessor.AddArg(overwriteFile);
// create an options
_cmdProcessor.AddArg(new CommandLineArgument("z", "overwrites with
zeroes"));
// create an option that takes data
_cmdProcessor.AddArg(new DataCommandLineArgument("n", "number of times the
file should be overwritten"));
then you need to process the command line by calling
// assuming args is the string[] from main
_cmdProcessor.ParseCmdLineToArgs(args);
then you need to loop through to find the ones that have been set. I do
something like this
foreach(CommandLineArgument argument in _cmdProcessor)
{
if (true == argument.Selected)
{
char ch = argument.Argument.ToString().ToCharArray()[0];
switch (ch)
{
case 'z':
// do something
break;
case '?':
PrintHelp();
break;
default:
throw new Exception(String.Format("found an weird arugment
{0}", ch));
}
}
There maybe better ways but this works for me. I use it in my command line
tools all the time. Hope it helps...

1. Is there a utility class out there that helps parse command line
arguments in a standard way?
2. I think I ran into a bug playing around with the command line.
When I send an asterisk "*" as one of the arguments I get some weird
stuff. On Windows it seems to work ok. Try the following with an
asterisk as one of the args:
using System;
class Program
{
static void Main(string[] args)
{
foreach (string s in args)
Console.WriteLine(s);
}
}
Thanks.
