How to create an advanced file searcher in C# using the FileSelectionManager library

This is how to use the pseudo-SQL features contained in the FileSelectionManager library for selecting and sorting files.

In order to do this, your application needs to receive a directory where it will search the files and pseudo-SQL sentence with the search criteria.

First of all you have to download the FileSelectionManager library, then create a console application and add the library to your project as a new reference

Next, write the following code:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

using System.IO;

using FileSelectionManager;

namespace ConsoleApplication1

{

    class Program

    {

        static void Main(string[] args)

        {

            if(args.Count()!=2 || !Directory.Exists(args[0]))

                throw new ArgumentException("Invalid Parameters");

            else

            {

                //Selecting Files

                FSM fManager = new FSM();

                fManager.Dir(args[0], true, args[1]);

                //Show results

                Console.WriteLine("Files Affected: " + fManager.AffectedFiles);

                Console.WriteLine("Files Involved: " + fManager.InvolvedFiles);

                foreach (System.IO.FileInfo file in fManager.SelectedFiles)

                {

                    Console.WriteLine("Found: {0} - {1} - {2} - {3} ",

                    file.DirectoryName,

                    file.Name,

                    file.CreationTime,

                    file.Length);

                }

            }

        }

    }

}

Imagine you have the following directory and files structure:

Compile your application and execute it, and give the directory the search criteria.
