Answer 1

You need to typecast the input. try using the following

int input = Convert.ToInt32(Console.ReadLine()); 

It will throw exception if the value is non-numeric.

Edit

I understand that the above is a quick one. I would like to improve my answer:

String input = Console.ReadLine();
int selectedOption;
if(int.TryParse(input, out selectedOption))
{
      switch(selectedOption) 
      {
           case 1:
                 //your code here.
                 break;
           case 2:
                //another one.
                break;
           //. and so on, default..
      }

} 
else
{
     //print error indicating non-numeric input is unsupported or something more meaningful.
}
