在构建接受参数的控制台应用程序时,可以使用传递给Main的参数(string[] args)。

在过去,我只是简单地索引/循环该数组,并做了一些正则表达式来提取值。然而,当命令变得更加复杂时,解析就会变得非常糟糕。

我感兴趣的是:

你使用的库 你使用的模式

假设命令总是遵循常见的标准,比如这里回答的。

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.

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/

Powershell Commandlets。

powershell根据命令行中指定的属性进行解析,支持验证、参数集、流水线、错误报告、帮助,最好的是返回。net对象供其他命令行使用。

一个非常简单易于使用的命令行解析专用类,它支持默认参数。

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