调用方法为 new demo().DemoTest();
public class demo
{
public delegate void DemoEventHandler();
public event DemoEventHandler eve;
public void DemoTest()
{
DemoEventHandler sync = new DemoEventHandler(SyncFunc);
DemoEventHandler sync2 = new DemoEventHandler(SyncFunc2);
DemoEventHandler asyc = new DemoEventHandler(AsycFunc);
eve += sync;
eve += sync2;
eve += asyc;
System.Console.WriteLine(System.DateTime.Now.ToString("HH:mm:ss fff") +" event start.");
eve();
System.Console.WriteLine(System.DateTime.Now.ToString("HH:mm:ss fff") + " event end.");
}
private void SyncFunc()
{
System.Console.WriteLine(System.DateTime.Now.ToString("HH:mm:ss fff") + " sync start.");
System.Threading.Thread.Sleep(1000);
System.Console.WriteLine(System.DateTime.Now.ToString("HH:mm:ss fff") + " sync end.");
}
private void SyncFunc2()
{
System.Console.WriteLine(System.DateTime.Now.ToString("HH:mm:ss fff") + " sync2 start.");
System.Threading.Thread.Sleep(2000);
System.Console.WriteLine(System.DateTime.Now.ToString("HH:mm:ss fff") + " sync2 end.");
}
private void AsycFunc()
{
System.Console.WriteLine(System.DateTime.Now.ToString("HH:mm:ss fff") + " asyc start.");
DemoEventHandler func = delegate()
{
System.Threading.Thread.Sleep(1000);
System.Console.WriteLine(System.DateTime.Now.ToString("HH:mm:ss fff") + " asyc end.");
};
func.BeginInvoke(null, null);
}
}
