我最近遇到了FubuCore命令行解析实现，我真的很喜欢它，原因是:

it's easy to use - although I couldn't find a documentation for it, the FubuCore solution also provides a project containing a nice set of Unit Tests that speak more about the functionality than any documentation could it has a nice object oriented design, no code repetition or other such things that I used to have in my command line parsing apps it's declarative: you basically write classes for the Commands and sets of parameters and decorate them with attributes to set various options (e.g. name, description, mandatory/optional) the library even prints a nice Usage Graph, based on these definitions

下面是一个简单的例子说明如何使用它。为了说明用法，我写了一个简单的实用程序，它有两个命令: - add(将一个对象添加到列表中-一个对象由一个名称(字符串)，值(int)和一个布尔标志组成) - list(列出当前添加的所有对象)

首先，我为'add'命令写了一个Command类:

[Usage("add", "Adds an object to the list")]
[CommandDescription("Add object", Name = "add")]
public class AddCommand : FubuCommand<CommandInput>
{
    public override bool Execute(CommandInput input)
    {
        State.Objects.Add(input); // add the new object to an in-memory collection

        return true;
    }
}

这个命令接受一个commandput实例作为参数，所以我下面定义它:

public class CommandInput
{
    [RequiredUsage("add"), Description("The name of the object to add")]
    public string ObjectName { get; set; }

    [ValidUsage("add")]
    [Description("The value of the object to add")]
    public int ObjectValue { get; set; }

    [Description("Multiply the value by -1")]
    [ValidUsage("add")]
    [FlagAlias("nv")]
    public bool NegateValueFlag { get; set; }
}

下一个命令是'list'，实现如下:

[Usage("list", "List the objects we have so far")]
[CommandDescription("List objects", Name = "list")]
public class ListCommand : FubuCommand<NullInput>
{
    public override bool Execute(NullInput input)
    {
        State.Objects.ForEach(Console.WriteLine);

        return false;
    }
}

'list'命令不带参数，所以我定义了一个NullInput类:

public class NullInput { }

现在剩下的就是在Main()方法中把它连接起来，就像这样:

    static void Main(string[] args)
    {
        var factory = new CommandFactory();
        factory.RegisterCommands(typeof(Program).Assembly);

        var executor = new CommandExecutor(factory);

        executor.Execute(args);
    }

程序按预期工作，在任何命令无效的情况下打印正确用法的提示:

  ------------------------
    Available commands:
  ------------------------
     add -> Add object
    list -> List objects
  ------------------------

下面是'add'命令的用法示例:

Usages for 'add' (Add object)
  add <objectname> [-nv]

  -------------------------------------------------
    Arguments
  -------------------------------------------------
     objectname -> The name of the object to add
    objectvalue -> The value of the object to add
  -------------------------------------------------

  -------------------------------------
    Flags
  -------------------------------------
    [-nv] -> Multiply the value by -1
  -------------------------------------

Genghis命令行解析器可能有点过时，但它的功能非常完整，对我来说工作得很好。

请使用apache commons cli API的。net端口。这很有效。

http://sourceforge.net/projects/dotnetcli/

以及用于概念和介绍的原始API

http://commons.apache.org/cli/

看看http://github.com/mono/mono/tree/master/mcs/class/Mono.Options/

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();
    }
}

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。
