Question

Could do with some help with this question.I am using the system.io, and I have to do things which require files to be moved, grouped, renamed. .

Working in command line application using c# so far I have moved some files from one directory to another, I now need to group some pdf files like so – B-12345 1.pdf, B-12345 2.pdf, B-12345 3.pdf, B-12345 4.pdf.I have been told I dont need to physically group them together just for the purposes of ensuring I only create one job per project reference(b-1234).

To give you a bit of background info on what im doing after these files are grouped I need to create a record in the job table sql database.But thats another question for another day just thought id give you some more info.

Mainly I just need info on how to read files that are in a file directory and grouping files, this would be very beneficial to me.?

To make the question a bit clearer this is the order in tasks should be done in the command line app.

1. Read files in directory (I have moved them so unsure on this?)
2. Group by project no (unsure)
3. Create job record in sql db
4. Move and rename file to correct location

Thanks in advance

My code is below

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.IO;

public class MoveForProcessing
{
    static void Main()
    {
        // move cad jobs to processing directory and delete former folder, use the System.IO.Path class.
        System.IO.Directory.Move(@"C:\Users\Ben\My Documents\Temp\", @"C:\Users\Ben\My Documents\Processing\");
    }
}

You could first declare a DirectoryInfo class of the dirctory in question

private System.IO.DirectoryInfo dir = System.IO.DirectoryInfo.Open(@"path");

Then get an array of FileInfo objects for each file in the directory

private FileInfo[] files = dir.GetFiles();

You could also put a wildcard string into GetFiles() if you want only certain file types

private FileInfo[] files = dir.GetFiles("*.pdf");

Then you can increment through the array doing whatever you need with each FileInfo object

foreach(FileInfo f in files)
{
   f.Move(); // or whatever you need to do
}
