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
}
}
.....
}
Cannot implicitly convert type 'System.EventHandler' to 'System.EventHandler<object>'

你能帮帮我吗？@H_301_4@
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.

DispatcherTimer timer = new DispatcherTimer();
public BlankPage()
{
this.InitializeComponent();
timer.Tick += timer_Tick;
}
protected void timer_Tick(object sender,object e)
{
timecounter--;
if (timecounter == 0)
{
//disable all buttons here
}
}
