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(xiàng)。
使用 CommandLineParser
CommandLineParser 是一個(gè)輕量級(jí)的工具，使用非常簡(jiǎn)答，官方也有教程。
選項(xiàng)類

using CommandLine.Text;
namespace CopyFiles
{

{
[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(biāo)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,

[HelpOption]

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