You can set e.Cancel=true; in CancelKeyPress event handler. I have tested the following code snippet. It works.

class Program
    {
        static void Main(string[] args)
        {
            Console.CancelKeyPress += Console_CancelKeyPress;

            while (true)
            {
                Thread.Sleep(100);
                Console.WriteLine("..");
            }
        }


        private static void Console_CancelKeyPress(object sender, ConsoleCancelEventArgs e)
        {
            e.Cancel = true;
            Console.WriteLine("Cancel key trapped. Execution will not terminate.");
        }
    }

Update:

You can use following property to achieve what you want.

Console.TreatControlCAsInput = true;

        while (true)
        {
            var k = Console.ReadKey(true);
            if ((k.Modifiers & ConsoleModifiers.Control) != 0)
            {
                if ((k.Key & ConsoleKey.C) != 0)
                {
                    break;
                }
            }

            Thread.Sleep(100);
            Console.WriteLine("..");
        }

I can stop the termination when Ctrl+C entered. Here i want to know how can i break the loop using Ctrl+C. — G.suren, Jul 26 '16 at 07:38
