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。
