How to Create and Switch between different C# Arrays

Hello  @Mohammed you can try this code for switch case

            Array Groceries_products = new Array[10];
            Array Electronics_products = new Array[10];
            Array Apparel_Products = new Array[10];
            int ch=0;

            while (ch!=4)
            {
                Console.WriteLine("Enter 1 for Groceries_products");
                Console.WriteLine("Enter 2 for Electronics_products");
                Console.WriteLine("Enter 3 for Apparel_Products");
                Console.WriteLine("Enter 4 for Exit");
                Console.WriteLine("Enter Your Choice");
                int.TryParse(Console.ReadLine(),out ch);

                switch (ch)
                {
                    case 1:
                        //Write   Code Here   For Groceries_products  Array
                        break;
                    case 2:
                        //Write   Code Here   For Electronics_products  Array
                        break;
                    case 3:
                        //Write   Code Here   For Apparel_Products  Array
                        break;
                    case 4:
                       
                        break;

                   
                }

            }

you can make any change in this code as your requirement.  i can't understand actually what do you need only i give a demo of switch .    ...
if you have  query then you can explain that for better understanding  ....
