How can I get a all the files present in a directory with their hashes as a Dictionary in C#?

I have a directory countaining a lot of files (around 650 files) and i want to get all the files present in this directory with their hash (something like sha256 or sha512) in a Dictionary while seeing the percentage of the operation? Because I assume that it would take some time to hash them.

You may want to consider trying this approach; based on similar cases, it has shown promising results and could potentially resolve the issue you’re encountering.

    public static async Task<Dictionary<string, string>> GetFilesAndHashesAsync(string pathToDirectory, IProgress<double>? progress = null)
{
    var filesDictionary = new Dictionary<string, string>();
    using (var sha = SHA256.Create())
    {
        if (!Directory.Exists(pathToDirectory))
        {
            throw new DirectoryNotFoundException($"Directory not found: {pathToDirectory}");
        }

        var files = Directory.EnumerateFiles(pathToDirectory).ToArray();
        var totalFiles = files.Length;
        double processedFiles = 0;

        foreach (var file in files)
        {
            using (var fileStream = File.OpenRead(file))
            {
                var hashBytes = await sha.ComputeHashAsync(fileStream);
                var hashString = BitConverter.ToString(hashBytes).Replace("-", string.Empty);
                filesDictionary.Add(Path.GetFileName(file), hashString);
            }

            processedFiles++;
            progress?.Report(processedFiles / totalFiles * 100);
        }
    }

    return filesDictionary;
}
