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);

你可能会喜欢我的地毯。Cmd

易于使用和扩展的命令行参数解析器。句柄:Bool，加/减，字符串，字符串列表，CSV，枚举。

内置/?帮助模式。

内置/??'和'/?D'文档生成器模式。

static void Main(string[] args) 
{            
    // create the argument parser
    ArgumentParser parser = new ArgumentParser("ArgumentExample", "Example of argument parsing");

    // create the argument for a string
    StringArgument StringArg = new StringArgument("String", "Example string argument", "This argument demonstrates string arguments");

    // add the argument to the parser 
    parser.Add("/", "String", StringArg);

    // parse arguemnts
    parser.Parse(args);

    // did the parser detect a /? argument 
    if (parser.HelpMode == false) 
    {
        // was the string argument defined 
        if (StringArg.Defined == true)
        {
            // write its value
            RC.WriteLine("String argument was defined");
            RC.WriteLine(StringArg.Value);
        }
    }
}

编辑:这是我的项目，因此这个答案不应该被视为来自第三方的认可。也就是说，我确实在我编写的每个基于命令行的程序中使用它，它是开源的，我希望其他人可以从中受益。

看起来每个人都有自己的宠物命令行解析器，我最好也添加我的:)。

这个库包含一个命令行解析器，它将使用命令行中的值初始化一个类。它有很多功能(我已经建立了很多年了)。

从文档中…

怪诞框架中的命令行解析具有以下关键特性:

Automatic initialization: Class properties are automatically set based on the command-line arguments. Default properties: Send in a value without specifying the property name. Value conversion: Uses the powerful ConvertEx class also included in BizArk to convert values to the proper type. Boolean flags: Flags can be specified by simply using the argument (ex, /b for true and /b- for false) or by adding the value true/false, yes/no, etc. Argument arrays: Simply add multiple values after the command-line name to set a property that is defined as an array. Ex, /x 1 2 3 will populate x with the array { 1, 2, 3 } (assuming x is defined as an array of integers). Command-line aliases: A property can support multiple command-line aliases for it. For example, Help uses the alias ?. Partial name recognition: You don’t need to spell out the full name or alias, just spell enough for the parser to disambiguate the property/alias from the others. Supports ClickOnce: Can initialize properties even when they are specified as the query string in a URL for ClickOnce deployed applications. The command-line initialization method will detect if it is running as ClickOnce or not so your code doesn’t need to change when using it. Automatically creates /? help: This includes nice formatting that takes into account the width of the console. Load/Save command-line arguments to a file: This is especially useful if you have multiple large, complex sets of command-line arguments that you want to run multiple times.

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();
    }
}

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

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();
    }
}
