C＃：如何检测键入到控制台应用程序中的参数？ [英] C#: How to detect arguments typed into console application?

问题描述

在C＃中检测到控制台应用程序的输入时我将如何处理？

How would I go upon detecting input for a console application in C#?

例如，我希望通过编写以下内容来启动控制台应用程序：
Welcome to Food Hut
（光标在第一行之后输入内容）

Let's say for example I want the console application to start up by writing: Welcome To Food Hut (cursor to type stuff here after the first line)

我希望控制台应用程序检测到两个命令：

I would want the console application to detect two commands:

1：/帮助-将显示一些帮助乱码。

1: /help - which will display some help gibberish.

2：/食品披萨-t意大利辣香肠-d百事可乐-它将显示所以，您想喝含意大利辣香肠和百事可乐的比萨饼吗？

2: /food pizza -t pepperoni -d pepsi - which will display "So you would like a Pizza with Pepperoni and Pepsi to drink?"

在首先检测到键入的/ command并读取参数后，我将如何处理？

How would I go upon detecting first what /command was typed and also reading the arguments like -t pepperoni (topping) and -d pepsi (to drink) if /food pizza was typed?

我的主要问题是弄清楚如何检测有史以来的第一个单词，例如-t意大利辣香肠（顶部）和-d百事可乐（饮用），例如？键入，弄清楚如果是/ help，则调用某种方法，该方法会将一些帮助文本发布到控制台中，或者如果命令是/ food，则读取/ food命令-t和-p之后的内容。 / p>

My main problem is figuring out how to detect the first word ever typed, figuring out that if it was /help then call some method that would post some help text into the console or if the command is /food then to read what is after the /food command, -t, and -p.

    static void Main(string[] args)
    {
        Console.WriteLine("Welcome To Food Hut");
        Console.ReadLine();

        // if readline equals to /help then display some help text.


        // if /food command is typed, read first argument after /food Pizza, -t TheTopping
        // and -p ForWhatToDrink

        // and then display, 'So you would like a Pizza with Pepperoni and Pepsi to drink?'
    }

推荐答案

我建议 Richard Lopes的命令线参数解析器。它功能强大且使用非常简单。此外，它接受各种指定参数的方式，例如：

I recommend Richard Lopes' Command Line Arguments Parser. It is powerful and very simple to use. Also, it accepts various ways of specifying the arguments, for example:

• / name = Stefan


• -name = Stefan


• -name =多个单词


• -名称'Stefan'

• /name=Stefan
• --name=Stefan
• --name="Multiple words"
• -name 'Stefan'

示例代码：

static void Main(string[] args)
{
    Arguments cmdline = new Arguments(args);

    Console.WriteLine(cmdline["name"]);
}
