Answer 1

what u have done is declared the stRefID variable inside the scope of the method GenerateID this is not gonna work so what u can do is put that variable within the scope of the class and then u can use it like this.

namespace Blackjack
   {
    public class Hit
      {
       string stRefID = "";

       public static string GenerateID(int MinSize, int MaxSize)
        {
        Random random = new Random();

        int iChosenMaxSize = random.Next(0, 11);

        int two = 2;
        int three = 3;
        int four = 4;
        int five = 5;
        int six = 6;
        int seven = 7;
        int eight = 8;
        int nine = 9;
        int ten = 10;
        int jack = 10;
        int queen = 10;
        int king = 10;
        int ace = 11;


     for (int x = 1; x <= iChosenMaxSize; x++)
    {
        int iCharType = random.Next(0, 12);
        switch (iCharType)
        {
                case 0:
                    stRefID += two;
                    break;
                case 1:
                    stRefID += three;
                    break;
                case 2:
                    stRefID += four;
                    break;
                case 3:
                    stRefID += five;
                    break;
                case 4:
                    stRefID += six;
                    break;
                case 5:
                    stRefID += seven;
                    break;
                case 6:
                    stRefID += eight;
                    break;
                case 7:
                    stRefID += nine;
                    break;
                case 8:
                    stRefID += ten;
                    break;
                case 9:
                    stRefID += ace;
                    break;
                case 10:
                    stRefID += jack;
                    break;
                case 11:
                    stRefID += queen;
                    break;
                case 12:
                    stRefID += king;
                    break;

            }
         } return stRefID; 

    }

this should work fine i guess
