如何为本地属性创建资源？

在我的 WPF UserControl 中，我有一个这样定义的属性：

    private Converters.CurrencyConverter _CurConverter = null;
    public Converters.CurrencyConverter CurConverter
    {
        get
        {
            if (_CurConverter == null)
                _CurConverter = new Converters.CurrencyConverter(decPlaces);

            return _CurConverter;
        }
    }

我想在我的 xaml 中为其设置资源，但我不确定如何执行此操作。我已经尝试过：

<UserControl.Resources>
    <ObjectDataProvider ObjectType="{x:Type LocalConverters:CurrencyConverter}"  ObjectInstance="{CurConverter}" x:Key="LocalCurConverter" />
</UserControl.Resources>

但这显然是不对的，并且它给出了如何使用 ObjectInstance 的问题。我还尝试在资源声明中创建对象，如下所示：

<UserControl.Resources>
    <LocalConverters:CurrencyConverter x:Key="CurConverter" />
</UserControl.Resources>

但这不起作用，因为我没有无参数构造函数。忘记这是一个转换器这一事实，如何在后面的代码中为属性创建资源？

谢谢

In my WPF UserControl, I've got a property defined as such:

    private Converters.CurrencyConverter _CurConverter = null;
    public Converters.CurrencyConverter CurConverter
    {
        get
        {
            if (_CurConverter == null)
                _CurConverter = new Converters.CurrencyConverter(decPlaces);

            return _CurConverter;
        }
    }

I want to set a resource to it in my xaml, but I'm not sure how to do it. I've tried this:

<UserControl.Resources>
    <ObjectDataProvider ObjectType="{x:Type LocalConverters:CurrencyConverter}"  ObjectInstance="{CurConverter}" x:Key="LocalCurConverter" />
</UserControl.Resources>

But that's obviously not right and it gives issues with how ObjectInstance is used. I've also tried to instead just create the object in the resource declaration as such:

<UserControl.Resources>
    <LocalConverters:CurrencyConverter x:Key="CurConverter" />
</UserControl.Resources>

But that doesn't work because I don't have a parameterless constructor. Forgetting about the fact that this is a converter, how can I create a resource to a property in the code behind?

Thanks
