Good morning

I have several txt files in the same directory milestones-1, milestones-2..., only that I need to create a file only. but with an aggravation that each file will be a column of the final file. as if it were an array. where each file is matrix column.

Someone could help me

    You need to give us more information so that we can try to respond. Anyway, did you do something? Are you having a specific problem?

The performative way is like this:

const int chunkSize = 2 * 1024; // 2KB
var inputFiles = new[] { "marcos1.txt", "marcos2.txt", "marcos3.txt" };
using (var output = File.Create("marcos-juntos.txt"))
{
    foreach (var file in inputFiles)
    {
        using (var input = File.OpenRead(file))
        {
            var buffer = new byte[chunkSize];
            int bytesRead;
            while ((bytesRead = input.Read(buffer, 0, buffer.Length)) > 0)
            {
                output.Write(buffer, 0, bytesRead);
            }
        }
    }
}

I took it from here.
