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/

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();
    }
}

        {
            return m_instance;

            return m_args[argName];
        }
        else return "";

        if (m_args.ContainsKey(argName))
        {
            return Convert.ToInt64(m_args[argName]);
        }
        else return 0;
    }

    public double argAsDouble(string argName)
    {
        if (m_args.ContainsKey(argName))
        {
            return Convert.ToDouble(m_args[argName]);
        }
        else return 0;
    }

    public void parseArgs(string[] args, string defaultArgs )
    {
        m_args = new Dictionary<string, string>();
        parseDefaults(defaultArgs );

        foreach (string arg in args)
        {
            string[] words = arg.Split('=');
            m_args[words[0]] = words[1];
        }
    }

    private void parseDefaults(string defaultArgs )
    {
        if ( defaultArgs == "" ) return;
        string[] args = defaultArgs.Split(';');

        foreach (string arg in args)
        {
            string[] words = arg.Split('=');
            m_args[words[0]] = words[1];
        }
    }

    private Dictionary<string, string> m_args = null;
    static readonly CommandLineArgs m_instance = new CommandLineArgs();
}

class Program
{
    static void Main(string[] args)
    {
        CommandLineArgs.I.parseArgs(args, "myStringArg=defaultVal;someLong=12");
        Console.WriteLine("Arg myStringArg  : '{0}' ", CommandLineArgs.I.argAsString("myStringArg"));
        Console.WriteLine("Arg someLong     : '{0}' ", CommandLineArgs.I.argAsLong("someLong"));

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。

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
  -------------------------------------

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。
