using System;

class Program
{
    enum Numbers { standard = 1, express = 2, same = 3 };

    const int A = 1, B = 2;
    const int Y = 3, N = 4;

        double cost, LB;
        int Number_of_items ;
        int myNumbers;
        char catagory = 'A';
        char surcharge = 'Y';

        Console.WriteLine("please enter the type of shiping you want");
        Console.WriteLine("Enter 1:standard shipping.");
        Console.WriteLine("Enter 2:express shipping.");
        Console.WriteLine("Enter 3:same day shipping.");

        myNumbers = int.Parse(Console.ReadLine());
        switch ((Numbers)myNumbers)
        {

A is an int variable to which you assigned the value 1. You probably meant to do: if (catagory=='A') not if (catagory==A)
