Hi, have you to match everything inside curly brackets? – Matteo Basso May 23 '19 at 16:15 — Matteo Basso, May 23 '19 at 16:15
Can there be more than one error per file? – Idle_Mind May 23 '19 at 16:29 — Idle_Mind, May 23 '19 at 16:29

I used the Regex Here from Milosz.

Your code, slightly modified:

static void Main(string[] args)
{
    Regex finderror = new Regex(@"(?<=\{)[^}]*(?=\})");
    DirectoryInfo id = new DirectoryInfo("E:\\student_copy\\text");
    FileInfo[] fiArrrr = id.GetFiles();
    foreach (FileInfo f in fiArrrr)
    {
        Console.WriteLine("File: " + f.FullName);
        string stuff = File.ReadAllText(f.FullName);
        Match errortext = finderror.Match(stuff);
        if (errortext.Success)
        {
            Console.WriteLine("Error Found:");
            Console.WriteLine(errortext.Value.Trim());
        }
        else
        {
            Console.WriteLine("No error for file.");
        }
    }
    Console.Write("Press Enter to quit");
    Console.ReadLine();
}
