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)
}
}
}
}
