Print(@"C:\...\deutsch.txt");

string[] ReadFile(string path) => File.Exists(path) ? File.ReadAllLines(path) : Array.Empty<string>();

bool IsAscending(string s) {
    for (int i = 1; i < s.Length; i++)
        if (s[i] <= s[i - 1]) return false;
    return true;
}

IEnumerable<string> GetAlphabetList(string path) => ReadFile(path).Where(x => IsAscending(x.ToLower()));

void Print(string path) => GetAlphabetList(path).ToList().ForEach(x => Console.WriteLine(x));
