It’s typical for a console app to be driven by args. Often these can be a complex set, e.g. MyApp.exe title:=bob maxSize:=300 outputFile:=results.txt

I keep re-using the following code, so I thought I’d share it;

var commands = CommandsFromArgs(args);
if (commands.ContainsKey("maxSize))
   var maxSize = commands["maxSize"];

/// <summary>
/// Commands from arguments.
/// </summary>
/// The arguments.
/// dictionary of commands
private static Dictionary<string,string> CommandsFromArgs(string[] args)
{
    var commands = new Dictionary();
    var splitter = new string[] { ":=" };
    foreach (var arg in args)
    {
        if (arg.Contains(":="))
        {
            var pair = arg.Split(splitter, StringSplitOptions.None);
            if (pair.Length == 2)
            {
                commands.Add(pair[0], pair[1]);
            }
        }
    }

    return commands;
}
