using System;
using System.Collections.Generic;
using System.Text;
using System.Diagnostics;namespace ConsoleApplication
{
    class Program
    {
        static void Main(string[] args)
        {
            int[] range = new int[33];
            for (int i = 0; i < 33; i++)//初始化范围集合，从1到33
            {

            }            int[] result = CreateRedBallNum(range, 6);            Console.WriteLine("RedBall is: ");            for (int i = 0; i < result.Length; i++)
            {
                Console.Write(result[i] + " ");
            }
            Console.WriteLine();            int BlueBall = CreateBlueBallNum();            Console.WriteLine("BlueBall is: ");            Console.WriteLine(BlueBall);            Console.ReadKey();
        }        //取出不重复的6个数（红球）
        static int[] CreateRedBallNum(int[] range, int count)
        {

            Random random = new Random();

            int temp = 0;
            for (int i = 0; i < count; i++)
            {
                index = random.Next() % (range.Length - i);
                result[i] = range[index];
                //将当前已使用过的数移至集合末尾，并且将末尾原来没有使用的数放到当前位置
                temp = range[range.Length - 1 - i];
                range[range.Length - 1 - i] = range[index];
                range[index] = temp;
            }            result = Sort(result);            return result;
        }
        //取蓝球
        static int CreateBlueBallNum()
        {
            int result = 0;            Random r = new Random();            result = r.Next(1, 16);            return result;
        }        //排序
        static int[] Sort(int[] range)
        {
            for (int i = 0; i < range.Length; i++)
            {
                int temp = range[i];
                int j = i;
                while ((j > 0) && (range[j - 1] > temp))
                {
                    range[j] = range[j - 1];
                    --j;
                    range[j] = temp;
                }
            }
            return range;
        }    }
}

Answer 2

呵呵，学生吧？ private void textBox1_LostFocus(object sender, EventArgs e)//窗体的textbox控件上失去光标事件来触发
        {
            if (textBox1.Text != "")
            {
                DataSet ds = new DataSet();
                SqlConnection conn = new SqlConnection("数据库连接字符串");//连接数据库
                SqlDataAdapter adp = new SqlDataAdapter("sql语句").Fill(ds);//执行sql语句
                if (textBox1.Text == ds.Tables[0].Rows[0].ToString())//将查询出来的结果来与textbox中值来比对
                {
                    MessageBox.Show("查询到！");//比对结果如果一样
                }
                else
                {
                    MessageBox.Show("未查询到！");//比对结果如果不一样
                }
            }
            else
            {
                MessageBox.Show("比对值不能为空！");
                return;
            }
        }用到部分数据库和简单控件事件，应该满足你要求吧~

Answer 3

private void button1_Click(object sender, EventArgs e)//单击button事件
{
   MessageBox.Show("单击成功！",MessageBoxButtons.OK,//指定按钮样式
MessageBoxIcon.Asterisk,//指定显示图片样式
MessageBoxDefaultButton.Button1);//指定默认按钮
   return;
}
