        {
            for (int x = 0; x < 5; x++)
            {

                for (int times = 0; times < 20; times++)
                {
                    string str = "<table border=" + " 2=" + "><tr>";
                    // string str1 = "<table border=" + " 2=" + " width=" + " 400=" + "><tr>";
                    var generated = 0;
                    var rand = new Random(DateTime.Now.Millisecond);
                    for (var i = 0; i < Rows; i++)
                    {
                        Card[i] = new int[Cols];
                    }

                    while (generated < (Cols * Rows))
                    {
                        var num = rand.Next(1, 90);

                        if (!Contains(num))
                        {
                            var row = generated / Cols;
                            var currentCol = generated - (row * 5);

                            if (!Card[row].Any(c => c > 0 && c / 10 == (num / 10)))
                            {
                                generated++;
                                Card[row][currentCol] = num;
                            }
                        }
                    }

                    for (var i = 0; i < Rows; i++)
                    {
                        Array.Sort(Card[i]);
                    }

                    for (var i = 0; i < Cols; i++)

                        SortNumber(i, 1, 2);
                        SortNumber(i, 0, 1);
                        SortNumber(i, 0, 2);

推荐答案

这是一个服务器端代码，只在加载页面后才会运行。您可以使用jQuery脚本向服务器发送请求以使用Ajax加载下一个票证。可以再次执行相同的代码来获取下一张票，但是使用jQuery来执行此操作。否则，您将不得不使用HTTP请求来获取数据。

This is a server side code and will run only once the page is loaded. You can use a jQuery script to send a request to the server to load the next ticket using Ajax. Same code can be executed again to get the next ticket, but use jQuery to do so. Since otherwise you will have to use an HTTP request to get the data.
