NetCore控制台实现自定义CommandLine功能

命令行科普:

例如输入: trans 123 456 789 -r 123 -r 789
上面例子中:trans是Command,123 456 789是CommandArgument,-r之后的都是CommandOption.注意:命令行的格式是固定的
Command是必须的,CommandArgument和CommandOption都是可选的
只有设置了CommandArgument的multipleValues为true后,CommandArgument才可以接受多个参数,单个参数和多个参数可以通过CommandArgument.Values获取
CommandOption设置了MultipleValue之后输入格式必须为-option optionvalue -option optionvalue...

NetCore插件:McMaster.Extensions.CommandLineUtils,项目源码:https://github.com/natemcmaster/CommandLineUtils

1、新建一个控制台项目

2、管理Nuget包。添加McMaster.Extensions.CommandLineUtils的引用

3、写代码

 1 using System;
 2 using System.Threading.Tasks;
 3 
 4 namespace Tree
 5 {
 6     class Program
 7     {
 8         static void Main(string[] args)
 9         {
10             CommandLine line = new CommandLine();
11             line.Run(args);
12         }
13     }
14 }

16             app.Command("trans", command =>
17             {
18                 //var args1 = new[] { "Arg1", "arg with space", "args ' with \" quotes" };
19                 //Process.Start("echo", ArgumentEscaper.EscapeAndConcatenate(args1));
20                 string password = Prompt.GetPassword("please input your password: ");
21                 //Process.Start(DotNetExe.FullPathOrDefault(), "run");
22                 CommandArgument argument = command.Argument("[name]", "", multipleValues: true);
23                 CommandOption option = command.Option("-t", "this is a template", CommandOptionType.NoValue);
24                 command.OnExecute(() =>

29                         if (!isRun)
30                         {
31                             return;
32                         }
33                         command.Out.WriteLine($"密码是{password}, 参数是:{argument}");
