示例需求

拷貝文件，如：CopyFiles -s "E:/Framework/Tenoner - 副本 (2)" -p "*.csproj" -t "E:/Framework/Tenoner - 副本 (2)/Bak"，可以支持：深度拷貝、拷貝符合指定模式的文件、是否覆蓋等選項。

使用 CommandLineParser
CommandLineParser 是一個輕量級的工具，使用非常簡答，官方也有教程。

選項類

復(fù)制代碼 代碼如下:

using System;

using System.Linq;
using System.Text;
using System.Threading.Tasks;

using CommandLine;
using CommandLine.Text;

namespace CopyFiles
{
    class Options
    {
        [Option(
            's', "source", Required = true,
            HelpText = "源目錄。")]
        public string SourcePath { get; set; }

        [Option(
            'p', "pattern", Required = true,
            HelpText = "文件模式。")]
        public string SearchPattern { get; set; }

        [Option(
            't', "target", Required = true,
            HelpText = "目標目錄。")]
        public string TargetPath { get; set; }

        [Option('a', "all", DefaultValue = true,
            HelpText = "是否包含所有目錄？")]
        public bool AllDirectories { get; set; }

        [Option('o', "overwrite", DefaultValue = true,
            HelpText = "是否覆蓋所有文件？")]
        public bool Overwrite { get; set; }

        [Option('v', "verbose", DefaultValue = true,
            HelpText = "是否打印消息？")]
        public bool Verbose { get; set; }

        [HelpOption]
        public string GetUsage()
        {
            return HelpText.AutoBuild(this);
        }

        public void WriteLine(string format, params object[] args)
        {
            if (this.Verbose)
            {
                Console.WriteLine(string.Format(format, args));
            }
        }
    }
}
