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网站的支持。
