基于C#实现简单的随机抽奖小程序

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();

  }

  }

}

以上代码就是实现抽奖小程序的全部代码，代码简单易懂，写的不好还请见谅，有好的意见欢迎留言，谢谢大家一直以来对服务器之家网站的支持。
