As if there weren't already enough answers here :0), the following encapsulates into a static method @kwl's solution above (the first one).

    public static string ConsoleReadLineWithTimeout(TimeSpan timeout)
    {
        Task task = Task.Factory.StartNew(Console.ReadLine);

        string result = Task.WaitAny(new Task[] { task }, timeout) == 0
            ? task.Result

        return result;
    }

Usage

    static void Main()
    {
        Console.WriteLine("howdy");
        string result = ConsoleReadLineWithTimeout(TimeSpan.FromSeconds(8.5));
        Console.WriteLine("bye");
    }
