C# arg parser

Monday, December 2nd, 2013

Since I posted a perl one. Note there’s probably some neat way to do this using system libraries that I just don’t know about, but this is what I use

As part of the class (you can have this as a class i.e. Config.cs, or as part of the program:


static readonly Dictionary argsDict = new Dictionary();

Parser:


static public void ArgHandler(string[] args)
{
foreach (string arg in args)
{
Regex quoteRE = new Regex(“\”(.*)\””);
string[] quoteResults = quoteRE.Split(arg);
string workarg;
if (quoteResults.Length > 1)
{
workarg = quoteResults[1];
}
else
{
workarg = arg;
}

Regex argRE = new Regex(“–(.*)=(.*)”);
string[] regResults = argRE.Split(workarg);
if (regResults.Length > 1)
{
Console.WriteLine(string.Format(” — {0} -> {1}”, regResults[1], regResults[2]));
argsDict.Add(regResults[1], regResults[2]);
}
}
}

Get a argument:


static public string GetArg(string arg)
{
string result = null;
argsDict.TryGetValue(arg, out result);
//if (debug)
// Console.WriteLine(“arg ” + arg + ” -> ” + result);
return result;
}

At the top of main(), call:


ArgHandler(args);
