WPF 4.8与静态属性结合

Question

我创建ViewBox程序Maticaly。 如何将此控制程序绑定到非静态类的静态特性。

var bindingHeight = new Binding("viewbox_height");
        bindingHeight.Source = Config.viewbox_height;
        bindingHeight.Mode = BindingMode.TwoWay;
        bindingHeight.UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged;
        MyViewbox.SetBinding(Viewbox.HeightProperty, bindingHeight);


public class Config
{
    public static event EventHandler<PropertyChangedEventArgs> StaticPropertyChanged;
    public static void OnPropertyChanged([CallerMemberName] string propertyname = null)
    {   
   StaticPropertyChanged?.Invoke(null, new PropertyChangedEventArgs(propertyname));
    }

这样不起作用。

Answer 1

将源设置为config的实例：

var bindingHeight = new Binding("viewbox_height");
bindingHeight.Source = new Config();
bindingHeight.Mode = BindingMode.TwoWay;
bindingHeight.UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged;
MyViewbox.SetBinding(Viewbox.HeightProperty, bindingHeight);

至少您在设置binding.source时犯了一个错误。在通常的实例属性的情况下，它应该是具有该属性的对象，在您的情况下，是“ config”的实例。对于静态属性，您无需设置binding.source。
