How to keep checking if a user presses esc while Reading lines?

Question

I want to keep reading lines of the user, but when this user presses on escape I want it to stop. But how can I keep reading single keys (for the escape), while meanwhile reading lines? I hope the question will be more clear after giving my code:

int number;
do
{
      string a = Console.ReadLine();
      try
      {
          Int32.TryParse(a, out number);
      }
      catch
      {
          Console.WriteLine("I only accept int");
      }
      finally
      {
          Console.Writeline(number);
      }
} while (Console.ReadKey(true).Key != ConsoleKey.Escape);

as you have written, you want to read lines until escape is pressed, but as your code says, you want to read only integers. Here's what I think is what you want,

        int number = 0;
        do
        {
            while (!Console.KeyAvailable)
            {
                string a = Console.ReadLine();
                bool bWriteNumber = false;
                try
                {
                    number = int.Parse(a);
                    bWriteNumber = true;
                }
                catch
                {
                    Console.WriteLine("Sorry! I only accept int");
                }
                finally
                {
                    if (bWriteNumber)
                        Console.WriteLine(number);
                }
            }
        } while (Console.ReadKey(true).Key != ConsoleKey.Escape);
