这是我基于Novell Options类编写的处理程序。

它针对的是执行while (input !="exit")样式循环的控制台应用程序，例如一个交互式控制台，例如FTP控制台。

使用示例:

static void Main(string[] args)
{
    // Setup
    CommandHandler handler = new CommandHandler();
    CommandOptions options = new CommandOptions();

    // Add some commands. Use the v syntax for passing arguments
    options.Add("show", handler.Show)
        .Add("connect", v => handler.Connect(v))
        .Add("dir", handler.Dir);

    // Read lines
    System.Console.Write(">");
    string input = System.Console.ReadLine();

    while (input != "quit" && input != "exit")
    {
        if (input == "cls" || input == "clear")
        {
            System.Console.Clear();
        }
        else
        {
            if (!string.IsNullOrEmpty(input))
            {
                if (options.Parse(input))
                {
                    System.Console.WriteLine(handler.OutputMessage);
                }
                else
                {
                    System.Console.WriteLine("I didn't understand that command");
                }

            }

        }

        System.Console.Write(">");
        input = System.Console.ReadLine();
    }
}

c# CLI是我编写的一个非常简单的命令行参数解析库。它是有据可查的开源软件。

WPF TestApi库提供了c#开发中最好的命令行解析器之一。我强烈推荐你去看看，这是Ivo Manolov关于API的博客:

// EXAMPLE #2:
// Sample for parsing the following command-line:
// Test.exe /verbose /runId=10
// This sample declares a class in which the strongly-
// typed arguments are populated
public class CommandLineArguments
{
   bool? Verbose { get; set; }
   int? RunId { get; set; }
}

CommandLineArguments a = new CommandLineArguments();
CommandLineParser.ParseArguments(args, a);

我喜欢这个，因为你可以为参数“定义规则”，不管是否需要，……

或者如果你是一个Unix的家伙，那么你可能会喜欢GNU Getopt . net端口。

我非常喜欢命令行解析器库(http://commandline.codeplex.com/)。它有一个非常简单和优雅的方式来通过属性设置参数:

class Options
{
    [Option("i", "input", Required = true, HelpText = "Input file to read.")]
    public string InputFile { get; set; }

    [Option(null, "length", HelpText = "The maximum number of bytes to process.")]
    public int MaximumLenght { get; set; }

    [Option("v", null, HelpText = "Print details during execution.")]
    public bool Verbose { get; set; }

    [HelpOption(HelpText = "Display this help screen.")]
    public string GetUsage()
    {
        var usage = new StringBuilder();
        usage.AppendLine("Quickstart Application 1.0");
        usage.AppendLine("Read user manual for usage instructions...");
        return usage.ToString();
    }
}

我建议使用开源库CSharpOptParse。它解析命令行，并将用户定义的. net对象与命令行输入结合起来。在编写c#控制台应用程序时，我总是使用这个库。
