请帮我解决问题…这里有一个简单的例子：

<Grid>
<CheckBox Content="Case Sensitive" Command="{Binding checkedCommand}"/>
</Grid>
public class ViewModel
{
public ICommand checkedCommand { get; set; }
public ViewModel()
{
checkedCommand = new CheckedCommand(this);
}
public void CheckedHandler()
{
//todo - implement your handler
}
}
public class CheckedCommand : ICommand
{
private ViewModel _vm = null;
public CheckedCommand(ViewModel _viewModel)
{
_vm = _viewModel;
}
public bool CanExecute(object parameter)
{
return true;
}
public event EventHandler CanExecuteChanged;
public void Execute(object parameter)
{
_vm.CheckedHandler();
}
}

}
// Using a DependencyProperty as the backing store for IsChecked. This enables animation, styling, binding, etc...

您基本上使用名称IsChecked来定义DependencyProperty。每次选中或取消选中时，都会调用在其中定义的回调方法。并且可能会看到一个关于如何从该静态方法访问实例字段的示例。祝你好运 下面是一个简单的例子：
