我正在
Windows 8 Visual Studio 11中开发一个应用程序,我想为DispatcherTimer实例定义一个事件处理程序,如下所示:
public sealed partial class BlankPage : Page { int timecounter = 10; DispatcherTimer timer = new DispatcherTimer(); public BlankPage() { this.InitializeComponent(); timer.Tick += new EventHandler(HandleTick); } private void HandleTick(object s,EventArgs e) { timecounter--; if (timecounter ==0) { //disable all buttons here } } ..... }
但是我得到以下错误:
Cannot implicitly convert type 'System.EventHandler' to 'System.EventHandler<object>'
我是widows 8应用程序的新手开发者.
你能帮帮我吗?
几乎拥有它:)你不需要实例化一个新的eventhandler对象,你只需要指向处理事件的方法.因此,一个事件处理程序.
