I created a player class and I am trying to use my player class with my menu driven player program but when I call my ProcessMenuItem I keep getting the error the name 'number' does not exist in current context. Any help would be appreciated.

//The MAXPLAYERS constant is the physical table size
            const Int32 MAXPLAYERS = 23;

            //Declare the player tables
            
            Player[] players = new Player[MAXPLAYERS];

            //Keep track of the actual number of players (i.e. logical table size)
            Int32 playerCount = 0;

            //Main Driver
            char menuItem;
            Console.WriteLine("Welcome to the player system...\n");
            menuItem = GetMenuItem();
            while (menuItem != 'X')
            {
                ProcessMenuItem(menuItem, number, lastName, goals, assists, players, ref playerCount, MAXPLAYERS);
                menuItem = GetMenuItem();
            }
            Console.WriteLine("\nThank you, goodbye");
            Console.ReadLine();
        }
        //new Player(number, firstName, lastName, goals, assists)
        //Returns either a 'C', 'R', 'U', 'D', 'L', or 'X' to the caller
        static char GetMenuItem()
        {
            char menuItem;
            DisplayMenu();
            menuItem = char.ToUpper(char.Parse(Console.ReadLine()));
            while (menuItem != 'C'
                && menuItem != 'L' && menuItem != 'X' && menuItem != 'R' && menuItem != 'U' && menuItem != 'D')
            {
                Console.WriteLine("\nError - Invalid menu item");
                DisplayMenu();
                menuItem = char.ToUpper(char.Parse(Console.ReadLine()));
            }
            return menuItem;
        }

        static void DisplayMenu()
        {
            Console.WriteLine("\nPlease pick an item:");
            Console.WriteLine("C - Create Player");
            Console.WriteLine("R - Retrive Player");
            Console.WriteLine("U - Update Player");
            Console.WriteLine("D - Delete Player");
            Console.WriteLine("L - List Players");
            Console.WriteLine("X - Exit");
        }

        //Routes to the appropriate process routine based on the user menu choice
        static void ProcessMenuItem(Char menuItem, Int32 number, String firstName, String lastName, Int32 goals,
            Int32 assists, Player[] players, ref Int32 playerCount, Int32 MAXPLAYERS, Int32 RemoveAt)
        {
            switch (menuItem)
            {
                case 'C':
                    ProcessCreate(number, firstName, lastName, goals, assists, players, ref playerCount, MAXPLAYERS);
                    break;
                case 'L':
                    ProcessList(number, firstName, lastName, goals, assists, players, ref playerCount);
                    break;
                case 'R':
                    ProcessRetrive( number, lastName, firstName, goals,  assists, players, ref playerCount, MAXPLAYERS);
                    break;
                    
                case 'U':
                    ProcessUpdate(number, firstName,lastName,goals ,assists, players, ref playerCount, MAXPLAYERS);
                    break;
                case 'D':
                    DeletePlayer(number, firstName,lastName,goals ,assists, players,ref playerCount, MAXPLAYERS, RemoveAt);
                       break;

            }
        }

I am not able to find any initialization for number in this code Snippet.
Did you missed it..?

If you did not declare 'number in a scope accessible by your code that uses it: of course, it does not exist.

You are calling the ProcessMenuItemmethod,and passing in the number argument.
But you need to declare it first as

int number=0;

then call the method

ProcessMenuItem(menuItem, number, lastName, goals, assists, players, ref playerCount, MAXPLAYERS);

ProcessMenuItem(menuItem, number, lastName, goals, assists, players, ref playerCount, MAXPLAYERS);
As others already noticed, you probably didn't declare the number parameter you are passing.
Please note, you are also passing less (8) parameters than expected (10) with qualifier mismatches (e.g. the method expected ref as 8th argument).
I would suggest you to change the method signature: pack so many parameters into an object and pass it to the method.
