1-33数中 随即抽取6个数的和是97  
  
用C#做桌面应用程序

每个数不能在一组里重复出现2次

如果再在一个TextBox里自己设置一个总和 然后在抽取  

还有 是1-33中  不能有0  

改如何实现

用C#做

还有 可不可以 一次性抽取多个6个数的数组

有没有人帮助一下

急需

先用random在1-33中间随机抽取5个数，然后用总和减去五个数如果得出的数是负数则继续前面的循环，直到减出的第六个数为正数

能不能提供下源码呢。。

给你一些代码：最后的textBox1.Text 就显示这几个数是什么！！
int sum = 0, total = 97;
            int numbert = 6;
            int i = 1;
            int temp = 0;
            int startnumber = 1, endnumber = 33;
            int[] number = new int[34];
            int[] random = new int[6];
            for(i=1;i<=endnumber;i++)
            {
                number[i] = i;
            }
            Random R =new Random();
            temp = R.Next(startnumber, endnumber);
            i = 1;
            random[0] = temp;
            do
            {
                for (i = 1; i < numbert; i++)
                {
                    random[i] = 0;
                    temp = R.Next(startnumber, endnumber);
                    for (int j = 1; j <= i; j++)
                    {
                        if (temp != random[j])
                        {
                            random[i] = temp;
                        }
                        else
                        {
                            temp = R.Next(startnumber, endnumber);
                        }
                    }
                }
                sum = 0;
                for (i = 0; i < numbert; i++)
                {
                    sum += random[i];
                }
            } while (sum!=total);

            string test = "";

            for (i = 0; i < numbert; i++)
            {
                test += random[i].ToString() + " ";
            }
            textBox1.Text = test;

收到的鲜花

• wwfhz123 于 2010-09-29 23:32 送鲜花  3朵   附言：好文章 谢谢

谢谢 我搞定了

我用我的方法做出来 能抽取随机数 但是有重复的

还有最后一个疑问 可以不可一次多抽取几组这样数组

最还还能排序一下 从小到大

刚刚测试了一下

还是有重复的随机数 为什么阿

        private void btnExtraction_Click(object sender, EventArgs e)
        {
            if (input())//验证为否为空
            {
                string Num;

                Num = txtNum.Text;

                int sum = 0, total = int.Parse(Num);

                int numbert = 6;
                int i = 1;
                int temp = 0;
                int startnumber = 1, endnumber = 33;
                int[] number = new int[34];
                int[] random = new int[6];
                for (i = 1; i <= endnumber; i++)
                {
                    number[i] = i;
                }
                Random R = new Random();
                temp = R.Next(startnumber, endnumber);
                i = 1;
                random[0] = temp;
                do
                {
                    for (i = 1; i < numbert; i++)
                    {
                        random[i] = 0;
                        temp = R.Next(startnumber, endnumber);
                        for (int j = 1; j <= i; j++)
                        {
                            if (temp != random[j])
                            {
                                random[i] = temp;
                            }
                            else
                            {
                                temp = R.Next(startnumber, endnumber);
                            }
                        }
                    }
                    sum = 0;
                    for (i = 0; i < numbert; i++)
                    {
                        sum += random[i];
                    }
                } while (sum != total);

                string test = "";

                for (i = 0; i < numbert; i++)
                {
                    test += random[i].ToString() + "    ";
                }
                txtNum1.Text = random[0].ToString();
                txtNum2.Text = random[1].ToString();
                txtNum3.Text = random[2].ToString();
                txtNum4.Text = random[3].ToString();
                txtNum5.Text = random[4].ToString();
                txtNum6.Text = random[5].ToString();
            }

还是有重复的 为什么阿

非常抱歉，逻辑计算有点失误，已经改正过来了：
int sum = 0, total = 97;
            int numbert = 6;
            int i = 1;
            int temp = 0;
            int startnumber = 1, endnumber = 33;
            int[] number = new int[34];
            int[] random = new int[6];
            for (i = 1; i <= endnumber; i++)
            {
                number[i] = i;
            }
            Random R = new Random();
            temp = R.Next(startnumber, endnumber);
            i = 1;
            random[0] = temp;
            do
            {
                for (i = 1; i < numbert; i++)
                {
                    random[i] = 0;
                    int j = 0;
                    bool flag = false;
                    temp = R.Next(startnumber, endnumber);
                    do
                    {
                        for (j=0; j <i; j++)
                        {
                            if (temp != random[j])
                            {
                                flag = true;
                            }
                            else
                            {
                                j = -1;
                                temp = R.Next(startnumber, endnumber);
                                flag = false;
                            }
                        }

                    } while (flag == false);
                    random[i] = temp;
                }
                sum = 0;
                for (i = 0; i < numbert; i++)
                {
                    sum += random[i];
                }
            } while (sum != total);

            string test = "";

            for (i = 0; i < numbert; i++)
            {
                test += random[i].ToString() + " ";
            }
            textBox1.Text = test;

如果想抽取多组呢。。
