添加新的 ApplicationBarMenuItem 图标时无法分配给属性 [英] Failed to assign to property when adding new ApplicationBarMenuItem icon

问题描述

我在 wp7 项目的页面上添加了一个带有图标的新 ApplicationBarMenu 按钮.尝试运行页面时，我得到:

I've added a new ApplicationBarMenu button with icon to a page in my wp7 project. when trying to run the page i get :

无法分配给属性'Microsoft.Phone.Shell.ApplicationBarIconButton.Click'.[行:56位置:124]

Failed to assign to property 'Microsoft.Phone.Shell.ApplicationBarIconButton.Click'. [Line: 56 Position: 124]

指向我添加的新菜单项按钮(第二个，send_report_button):

Which points to the new menu item button i have added (the second one, send_report_button ):

<phone:PhoneApplicationPage.ApplicationBar>
    <shell:ApplicationBar IsVisible="True" IsMenuEnabled="True">
        <shell:ApplicationBarIconButton x:Name="take_photo_button" IconUri="/Images/appbar.feature.camera.rest.png" Text="Take photo" Click="TakePhotoClick" />
        <shell:ApplicationBarIconButton x:Name="send_report_button" IconUri="/Images/mail.sent.png" Text="Send report" Click="SendReportClick" />
        <shell:ApplicationBarIconButton x:Name="logout_button" IconUri="/Images/appbar.logout.rest.png" Text="Logout"/>
        <shell:ApplicationBar.MenuItems>
            <!--<shell:ApplicationBarMenuItem x:Name="menuItem1" Text="MenuItem 1"/>
            <shell:ApplicationBarMenuItem x:Name="menuItem2" Text="MenuItem 2"/>-->
        </shell:ApplicationBar.MenuItems>
    </shell:ApplicationBar>
</phone:PhoneApplicationPage.ApplicationBar>

我已经检查了十次我在 .xaml.cs 中有一个方法:

I have checked ten times that i have a method in the .xaml.cs :

private void SendReportClick(object sender, RoutedEventArgs e)

但是，VS 似乎还是没有识别出来，或者其他地方出了问题.

But still, VS doesnt seem to recognize it, or something else is wrong.

谢谢

推荐答案

问题出在事件处理程序签名中.您将 RoutedEventArgs 作为第二个参数.它应该只是 EventArgs.

The problem is in the event handler signature. You have RoutedEventArgs as the second parameter. It should just be EventArgs.

这里有说明.不要忘记 app bar 是一个 shell 对象.

Here is an explanation. Don't forget that the app bar is a shell object.
