c# - 在C＃中解析命令行参数的最佳方法？ [关闭](Best way to parse command line arguments in C#? [closed])

Question

When building console applications that take parameters, you can use the arguments passed to Main(string[] args) .

(构建带有参数的控制台应用程序时，可以使用传递给Main(string[] args) 。)

In the past I've simply indexed/looped that array and done a few regular expressions to extract the values.

(过去，我只是索引/循环该数组，并做了一些正则表达式来提取值。)

However, when the commands get more complicated, the parsing can get pretty ugly.

(但是，当命令变得更复杂时，解析可能会变得很丑陋。)

So I'm interested in:

(所以我对以下内容感兴趣：)

• Libraries that you use

  (您使用的库)

• Patterns that you use

  (您使用的模式)

Assume the commands always adhere to common standards such as answered here .

(假定命令始终遵循通用标准，例如此处回答 。)

Answer 1

I would strongly suggest using NDesk.Options ( Documentation ) and/or Mono.Options (same API, different namespace).

(我强烈建议使用NDesk.Options （ 文档 ）和/或Mono.Options （相同的API，不同的名称空间）。)

An example from the documentation :

(文档中的示例 ：)

bool show_help = false;
List<string> names = new List<string> ();
int repeat = 1;

var p = new OptionSet () {
    { "n|name=", "the {NAME} of someone to greet.",
       v => names.Add (v) },
    { "r|repeat=", 
       "the number of {TIMES} to repeat the greeting.
" + 
          "this must be an integer.",
        (int v) => repeat = v },
    { "v", "increase debug message verbosity",
       v => { if (v != null) ++verbosity; } },
    { "h|help",  "show this message and exit", 
       v => show_help = v != null },
};

List<string> extra;
try {
    extra = p.Parse (args);
}
catch (OptionException e) {
    Console.Write ("greet: ");
    Console.WriteLine (e.Message);
    Console.WriteLine ("Try `greet --help' for more information.");
    return;
}
