Neat String interpolation

C#
foreach(file in files){
//Process file
Console.WriteLine($"Processed File [{file.Nr}/{files.Count}]");
}

C#
foreach(file in files){
//Process file
Console.WriteLine($"Processed File [{file.Nr}/{files.Count}]");
}

I have this little something, and I want the counter to stay fixed width so [ 1/50] instead of [1/50] how can I do this ? As simple as possible, I just want it to look neat not write a TUI framework. I found $"{val , fixedWidth}" but that only works with constants so it can't adapt if I reach 100 files.

{file.Nr,2} IIRC? Or -2 One is leftpad, other is rightpad Can't remember which is which

foreach(var file in files){
    //Process file
    var fileNr = file.Nr.ToString().PadLeft(files.Count.ToString().Length, ' ');
    Console.WriteLine($"Processed File [{fileNr}/{files.Count}]");
}

foreach(var file in files){
    //Process file
    var fileNr = file.Nr.ToString().PadLeft(files.Count.ToString().Length, ' ');
    Console.WriteLine($"Processed File [{fileNr}/{files.Count}]");
}

I suppose that's the best it's gonna get, thx

omg please assign files.Count.ToString().Length to a variable outside the foreach instead of calculating it every cycle also if you do that you can use the format inside the $"..." like {fileNr,pad} like Z²⁵ said

no {value,pad} requests a const value, so i can't calculate it after loading my files.

string.Format($"[{{0}},{pad}/{{1}}]", nr, count)

string.Format($"[{{0}},{pad}/{{1}}]", nr, count)

IList<File> files = GetFiles();
int filesCount = files.Count;
int digitsCount = filesCount.ToString().Length;

foreach (var file in files)
{
    string order = file.Number.ToString().PadLeft(digitsCount, ' ');
    string output = $"Processed File [{order}/{filesCount}]";
    Console.WriteLine(output);
    await Task.Delay(500); // simulating delay...
}

static IList<File> GetFiles(int N = 100) =>
    Enumerable
    .Range(0, N)
    .Select(x => new File(x + 1, Path.GetRandomFileName()))

public record File(int Number, string Name);

thx but, we were done already

I know this has been solved already but there is a decent CUI framework thingy that I found pretty nice for looking things pretty https://github.com/spectreconsole/spectre.console

And it wasn't what I looked for, for that specific script. But it looks very interesting to have in my Toolbox, so Thank you very much regardless.

yeah, not really what you asked for but it is a great lib if you write a lot of CLI stuffs :D
