我有一个使用 Mvvm Light 和 Ninject 的 wpf 应用程序。在我的本地机器上,RelayCommand 工作正常,当我将应用程序移动到另一台服务器时,它不再调用该方法(不会弹出消息框)。
在 MainViewModel.cs 我有
public ICommand GoClickCommand
{
get
{
return new RelayCommand(() => MessageBox.Show("Directly in property!"), () => true);
}
}
在 MainWindow.xaml 我有
`<Button Content="Go" HorizontalAlignment="Left" Margin="508,54,0,0" VerticalAlignment="Top" Width="75"
Command="{Binding GoClickCommand}" IsDefault="True" Click="btn_go_Click"/>`
我在调用 btn_go_click 后面的代码中有一个方法,该方法在单击按钮时被调用,这只是为了确保按钮实际工作。我不确定它是否与 Ninject 有关。我正在尝试使应用程序自包含(只有一个 .exe 文件),因此我在 App.xaml.cs 文件中有代码来解决缺少的程序集。我尝试在没有此代码的情况下运行该应用程序,该应用程序需要的唯一 2 个程序集是 GalaSoft.MvvmLight.WPF.dll 和 Ninject.dll。我注释掉了代码并将这两个程序集放在与应用程序相同的文件夹中,并且 RelayCommand 仍然没有触发。实际应用程序中的代码更复杂,我更改了 GoClickCommand 属性中的代码以尝试找出问题所在。感谢您的任何帮助或建议。
