C# 具有给定用户输入的数组的队列

在看过一些在线教程之后，我一直在尝试使用数组编写一个队列算法，数组中的数字来自用户输入。当我运行程序时，删除选项似乎不能正常工作，因为我第一次运行删除选项时，它总是说值为0，但当继续删除选项时，它总是删除最后输入的值，而不是第一个值

 {
  class Program
{
    static void Main(string[] args)
    {
        int max = 10;
        int []a;//array
        a = new int[max + 1];
        int b; //user input
        int front = 0;
        int rear = 0;

        int j = 0;

        do
        {
            Console.WriteLine
                 ("What do you want to do?");

            Console.WriteLine();

            Console.WriteLine("Add = 1");
            Console.WriteLine("Delete = 2");
            Console.WriteLine("Exit = 3");

            Console.WriteLine();

            b = int.Parse(Console.ReadLine());

            Console.WriteLine();

            if (b == 1)
            {
                Console.WriteLine("You selected to Add");

                if (rear == max)
                { 
                    Console.WriteLine("The Queue is full");

            }

            else
                Console.WriteLine("What value do you want to add?");

            int v; //value
            v = int.Parse(Console.ReadLine());
            j++;
                a[j] = v;
            rear++;

           else if (b == 2)

        {
            Console.WriteLine();
            Console.WriteLine("You selected to Delete");


                if (front == rear)
                {
                    Console.WriteLine(" Queue is empty");
                }

                else

                    Console.WriteLine("The deleted value is:" + a[front++]);

            }

         else if (b == 3)
            {
                Console.WriteLine("Exit program");
                Console.WriteLine();
                Console.WriteLine("Press Enter to exit");
                Console.ReadLine();
                Environment.Exit(0);

            }
            else

            {
                Console.WriteLine("Enter a matching option");
                Console.WriteLine();
            }

        } while (b != 'X') ;
    }
}
}

语句需要在Add块中重新排列，如下所示（j++操作需要移到[j]=v操作旁边）：

调试代码比您想象的要容易。它还将帮助您更多地了解代码执行时会发生什么，并帮助您编写更好的代码。

int v; //value
v = int.Parse(Console.ReadLine());
a[j] = v;
j++;
rear++;
