Sample requirements

Copy files, such as: CopyFiles-s "E:\ Framework\ Tenoner-copy (2)"-p "* .csproj"-t "E:\ Framework\ Tenoner-copy (2)\ Bak", can support: deep copy, copy files that match the specified pattern, whether to overwrite and other options.

Use CommandLineParser

CommandLineParser is a lightweight tool that is very easy to answer, and there are official tutorials.

Option class

The copy code is as follows:

Using System

Using System.Collections.Generic

Using System.Linq

Using System.Text

Using System.Threading.Tasks

Using CommandLine

Using CommandLine.Text

Namespace CopyFiles

{

Class Options

{

[Option (

'sworn, "source", Required = true

HelpText = "Source directory.")]

Public string SourcePath {get; set;}

[Option (

'paired, "pattern", Required = true

HelpText = "File mode.")]

Public string SearchPattern {get; set;}

[Option (

'tasking, "target", Required = true

HelpText = "destination directory.")]

Public string TargetPath {get; set;}

[Option ('averse, "all", DefaultValue = true)

HelpText = "does it include all directories?")]

Public bool AllDirectories {get; set;}

[Option ('oiled, "overwrite", DefaultValue = true)

HelpText = "overwrite all files?")]

Public bool Overwrite {get; set;}

[Option ('vested, "verbose", DefaultValue = true)

HelpText = "do you want to print messages?")]

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))

}

}

}

}

Tool class

The copy code is as follows:

Using System

Using System.Collections.Generic

Using System.Linq

Using System.Text

Using System.Threading.Tasks

Using CommandLine

Using Happy.Utils

Namespace CopyFiles

{

Class Program

{

Static void Main (string [] args)

{

Var options = new Options ()

If (Parser.Default.ParseArguments (args, options))

{

FileUtil.Copy (

Options.SourcePath

Options.SearchPattern

Options.TargetPath

(sourceFile, targetFile) = >

{

Options.WriteLine ("copy files: {0} to {1}", sourceFile, targetFile)

}

(exceptionInfo) = >

{

Options.WriteLine (exceptionInfo.Exception.Message)

ExceptionInfo.ExceptionHandled = true

}

Options.AllDirectories

Options.Overwrite)

}

}

}

}
