Question

怎么实现定时触发事件 比如想定时向数据库中插入数据

Answer 1

添加一个全敏野局应用程序类，在里面岁庆添加如下代码：
void Application_Start(object sender, EventArgs e) {
Timer t = new Timer(3000); //每隔3秒
t.Enabled = true;

t.AutoReset = true;
t.Elapsed += new ElapsedEventHandler(aaa);
GC.KeepAlive(t);

}
//把下桥雀喊面方法中改成你的数据库操作即可
public void aaa(object sender, ElapsedEventArgs e)
{ FileStream fs = new FileStream("d://a.txt", FileMode.Create);
StreamWriter sw = new StreamWriter(fs);

sw.WriteLine(DateTime.Now);

sw.Close();

fs.Close();
}
