copied!<p>This is a fairly old post, but here's something I devised and use in all of my console applications. It's just a small snippet of code that can be injected into a single file and everything will work.</p> <p><a href="http://www.ananthonline.net/blog/dotnet/parsing-command-line-arguments-with-c-linq" rel="nofollow">http://www.ananthonline.net/blog/dotnet/parsing-command-line-arguments-with-c-linq</a></p> <p>Edit: This is now available on <a href="http://www.nuget.org/packages/declcmdparser" rel="nofollow">Nuget</a>, and is part of the open-source project <a href="http://codeblocks.codeplex.com/" rel="nofollow">CodeBlocks</a>.</p> <p>It was devised to be declaratively and intuitively used, like so (another usage example <a href="http://codeblocks.codeplex.com/wikipage?title=Declarative%20command%20line%20parser%20sample&referringTitle=Home" rel="nofollow">here</a>):</p> <pre><code>args.Process( // Usage here, called when no switches are found () => Console.WriteLine("Usage is switch0:value switch:value switch2"), // Declare switches and handlers here // handlers can access fields from the enclosing class, so they can set up // any state they need. new CommandLine.Switch( "switch0", val => Console.WriteLine("switch 0 with value {0}", string.Join(" ", val))), new CommandLine.Switch( "switch1", val => Console.WriteLine("switch 1 with value {0}", string.Join(" ", val)), "s1"), new CommandLine.Switch( "switch2", val => Console.WriteLine("switch 2 with value {0}", string.Join(" ", val)))); </code></pre>
