C#實現航班預訂系統
本文實例為大傢分享瞭C#實現航班預訂的具體代碼,供大傢參考,具體內容如下
連接數據庫
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Data; using System.Data.SqlClient; namespace MyTickets { public class DBHelper { //數據庫連接字符串 public string connString = @"Data Source=.;Initial Catalog=MyTicket;Trusted_Connection=Yes;Connect Timeout=90"; /// <summary> /// 數據庫連接對象 /// </summary> private SqlConnection connction; public SqlConnection Connction { get { if (connction == null) { connction = new SqlConnection(connString); } return connction; } } /// <summary> /// 打開數據庫連接 /// </summary> public void OpenConnection() { if (connction.State == ConnectionState.Closed) { Connction.Open(); } else if (connction.State == ConnectionState.Broken) { Connction.Close(); Connction.Open(); } } /// <summary> /// 關閉數據庫連接 /// </summary> public void CloseConnection() { if(connction.State==ConnectionState.Open|| connction.State == ConnectionState.Broken) { Connction.Close(); } } } }
開頭動畫代碼
