Introduction

ConsoleAppLauncher is a Windows Console Application wrapper for .NET written in C#.

It captures all the output generated in the console and provides simple interface to start and close console application. The ConsoleOutput event is fired every time when a new line is written by the console to standard/error output. The lines are queued and guaranteed to follow the output order.

For rationale see this SO question.

Samples

Usage samples are available in the ConsoleAppLauncher.Samples project.

    // Run simplest shell command and return its output.
    public static string GetWindowsVersion()
    {
        return ConsoleApp.Run("cmd", "/c ver").Output.Trim();
    }

    // Run ipconfig.exe and return matching line.
    public static string GetIpAddress()
    {
        var output = ConsoleApp.Run("ipconfig").Output;
        var match = Regex.Match(output, "IPv4 Address.*: (?<addr>.*)");
        return match.Success ? match.Groups["addr"].Value : "<undefined>";
    }

    // Run ping.exe asynchronously and return roundtrip times in a callback
// sample call:
    //    Action<string> action = Console.WriteLine;
    //    PingUrl("google.com", action);         
    public static void PingUrl(string url, Action<string> replyHandler)
    {
        var regex = new Regex("(time=|Average = )(?<time>.*?ms)", RegexOptions.Compiled);
        var app = new ConsoleApp("ping", url);
        app.ConsoleOutput += (o, args) =>
        {
            var match = regex.Match(args.Line);
            if (match.Success)
            {
                var roundtripTime = match.Groups["time"].Value;
                replyHandler(roundtripTime);
            }
        };
        app.Run();
        app.WaitForExit();
    }

    // Get Windows firewall rule
    public static string GetFirewallRule(string ruleName)
    {
        var cmdLine = string.Format("advfirewall firewall show rule \"{0}\" verbose", ruleName);
        return ConsoleApp.Run("netsh", cmdLine).Output.Trim();
    }
