空話不多說了,直接給年夜家貼代碼了。詳細代碼以下所示:
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("祝賀\n"+s+"\n取得"+prize); myconn.Close(); } } }
以上代碼就是完成抽獎小法式的全體代碼,代碼簡略易懂,寫的欠好還請見諒,有好的看法迎接留言,感謝年夜家一向以來對網站的支撐。
