Wpf 从代码隐藏到XAML

我在.cs文件中有下面的C#代码，我想把它移到XAML中。 代码包括名为：OperationConverte的属性

Binding binding1 = new Binding("DisplayNames") 
    { 
       Source = OperationConverter, 
    }; 
    ComboBox4.SetBinding(ComboBox.ItemsSourceProperty, binding1); 


    Binding binding2 = new Binding("Operation") 
                      { 
                         Mode = BindingMode.TwoWay, 
                         Converter = (OperationConverter as IValueConverter) 
                      }; 
    ComboBox4.SetBinding(ComboBox.SelectedValueProperty, binding2);     

所以我所做的是：

   <ComboBox Name="ComboBox4" MinWidth="100"  ItemsSource="{Binding Path=OperationConverter.DisplayNames}" 
                               SelectedValue="{Binding Path=Operation, Mode=TwoWay, 
                               Converter={?????DONT KNOW WHAT TO DO HERE????}}" Margin="30,123,83,148" />

但是我不知道如何连接OperationConverter有多种方法，但标准做法是将转换器的实例声明为资源并引用它

<Window.Resources>
    <local:OperationConverter x:Key="MyConverter" />
</Window.Resources>

您当前公开转换器的方式最好是完全不实现IValueConverter，而是公开OperationConverter对象的转换值并直接绑定到该属性。

对不起，我不理解：“从OperationConverter对象公开转换后的值并直接绑定到该属性。”

SelectedValue="{Binding Path=Operation, Mode=TwoWay, Converter={StaticResource MyConverter}}"
