help needed for new programmer

[shahina]

hi i want to sort this array using c# to find maximum and minimum values from the 10 numbers entered.

            int[] marks = new int [9];
            
            int max=0;
            int min=0;
            int x;
            int y;
            
            Console.WriteLine("enter the marks of ten students and i will tell u which is maximum and minimum");



            for (x = 0; x < marks.Length; x++)
            {


                marks[x] = Convert.ToInt32(Console.ReadLine());


                //min = marks[0];
            }


            for (y = 0; y < marks.Length; y++)
            {
                //here if starting no is greater than ending no than it will display the lowest and highest no

                if (min<marks[0])
                {
                    min = marks[0];



                    Console.WriteLine("{0} is the minimum", min);
                    Console.ReadLine();
                }

                else if (min>marks[1])
                {
                    max = marks[1];
                    Console.WriteLine("{0} is the maximum", max);

                    Console.ReadLine();

                }
            




                //}

                // Console.WriteLine("the highest is {0} and the lowest is {1}", marks,min);
            }
