                if (count == 97)            //符合条件 ---(可以与界面上的某个textbox中的值进行比较).
                {
                    this.TextBox1.Text = showInts;  //输出需要的结果
                    return;                 //结果查询

                count = 0;                  //一次未打到合适的数字,清空总和,用于下一次计算
                showInts = "";              //同上
            }

这里是取得一组数字.
如果想多组,直接控制while即可.

这串代码 应该把while放在何处阿...

你的代码太多了,呵呵,用我的代码比较好.

        /// <summary>
        /// 从int数组中随机取数字,符合条件便输出
        /// </summary>
        /// <param name="intList">存放数字的数组</param>
        /// <param name="num">每一组数据需要取得的数字个数</param>
        /// <param name="count">需要取多少组这样的数字</param>
        /// <param name="condition">取得的一组数字中的总和</param>
        /// <returns></returns>
        static private List<List<int>> GetRandomInts(int[] intList, int num, int count, int condition)
        {
            List<List<int>> intsResult = new List<List<int>>();

            //查询随机的六个数字
            var tempList = from t1 in intList
                           orderby Guid.NewGuid()
                           select t1;

            int sum = 0;                        //用于保存六个数字计算的总和

            while (intsResult.Count < count)    //如果还未取满count组数字
            {
                List<int> subItem = new List<int>();
                foreach (int st in tempList.Take(num))    //tempList.Take(num)取六个数字,这里可根据变化而改变
                {
                    sum += st;                  //循环计算总和
                    subItem.Add(st);            //循环累积数字
                }

                if (sum == condition)            //符合条件并
                {
                    subItem.Sort();             //排序 
                    intsResult.Add(subItem);    //结果查询
                }

                subItem = null;
                sum = 0;                  //清空总和,用于下一次计算
            }
            return intsResult;
        }

调用:

            int[] intList = new int[33];    //你的数据集合

            for (int i = 1; i <= 33; i++)   //为数组添加数据
            {
                intList[i - 1] = i;
            }

            //表示多intList中取数字
            //6:表示每一组数字取6个
            //2:需要取多少组这样的数字
            //97:每一组数字的总和
            List<List<int>> intsResult = GetRandomInts(intList, 6, 2, 97);    //intsResult 就是所要的东西

我把你的代码 放到C#里会报错

好多语法 我都没见过

            var tempList = from t1 in intList
                           orderby Guid.NewGuid()
                           select t1;
这个就不知道什么意思

我是用的2008.
2005里跑不起来的,嘿嘿
