临近春节，大街小巷的地方都有抽奖活动，那么基于C#是如何实现简单的抽奖程序的呢，下面小编给大家分享了具体代码，有需要的朋友参考下

废话不多说了，直接给大家贴代码了。具体代码如下所示：

				?

									using System;

									using System.Collections.Generic;

									using System.ComponentModel;

									using System.Data;

									using System.Drawing;

									using System.Linq;

									using System.Text;

									using System.Threading.Tasks;

									using System.Windows.Forms;

									using System.Data.SqlClient;

									namespace ChouJiang

									{

									 public partial class Form1 : Form

									 {

									 public Form1()

									 {

									 InitializeComponent();

									 }

									private void button1_Click(object sender, EventArgs e)

									 {

									 int number = Convert.ToInt32(textBox1.Text.ToString());

									 string prize=comboBox1.Text.ToString();

									 string conn = "";

									 string sql = "";

									 string s = "";

									 conn = "server=XTFLZ-PC;database=Xtf;uid=sa;pwd=123456";

									 sql = "select *from Ticket";

									 SqlConnection myconn = new SqlConnection(conn);

									 myconn.Open();

									 SqlDataAdapter sda = new SqlDataAdapter(sql,myconn);

									 DataSet ds=new DataSet();

									 sda.Fill(ds,"Ticket");

									 dataGridView11.DataSource = ds;

									 dataGridView11.DataMember = "Ticket";

									 Random rd = new Random();

									 for (int i = 0; i < number; i++)

									 {

									 int tmp = rd.Next(1, 5);

									 s += dataGridView11.Rows[i].Cells["WorkerID"].Value.ToString() +

									 dataGridView11.Rows[i].Cells["Name"].Value.ToString() + "\n";

									 }

									 MessageBox.Show("恭喜\n"+s+"\n获得"+prize);

									 myconn.Close();

									 }

									 }

									}
