NetCore控制台实现自定义CommandLine功能

场景：我们在网上下载了一个第三方的软件（比如Nodejs），安装之后就可以再控制台输入命令，操作程序运行。这就是自定义CommandLine功能

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 
 3 namespace Tree
 4 {
 5     class Program
 6     {
 7         static void Main(string[] args)
 8         {
 9             string userCommand = "";
10             while (userCommand.ToLower() != "exit")
11             {
12                 userCommand = Console.ReadLine();
13                 string[] input = userCommand.Split(" ");
14                 CoreOptions.Run(input);
15             }
16             Console.ReadKey();
17         }
18     }
19 }

19             app.OnExecute(() =>
20             {
21                 if (numberOption.HasValue())
22                 {
23                     app.Out.WriteLine("write your logic, this is just a test");
24                 }
25                 // you can add more else if to judge all command
26                 else
27                 {
28                     app.Out.WriteLine("No such command");
29                 }
30             });
31             app.Execute(args);
32         }
