如何在XAML中引用当前对象

I cant' figure out how to reference the current instance object defined by the XAML file in the XAML file.

我无法弄清楚如何引用XAML文件中XAML文件定义的当前实例对象。

I have a converter that I want to send in the current instance as the parameter object.

我有一个转换器，我想在当前实例中作为参数对象发送。

{Binding Path=<bindingObject>, Converter={x:Static namespace:Converter.Instance}, ConverterParameter=this}

In this code this is converted to a string instead of a reference to the current instance object.

在此代码中，它将转换为字符串，而不是对当前实例对象的引用。

Thanks

谢谢

Technically, the ConverterParameter is not a DependencyProperty, so you can't bind to it. It would be nice to do a ConverterParameter={Binding ElementName=this}, but you can't bind to a non-dependency property.

从技术上讲，ConverterParameter不是DependencyProperty，因此您无法绑定它。做一个ConverterParameter = {Binding ElementName = this}会很好，但你不能绑定到非依赖属性。

But, someone figure it out how to do it here. This is however a bit complicated.

但是，有人在这里弄清楚如何做到这一点。然而，这有点复杂。

According to the Data Binding Overview, you can use the "/" to indicate the current item. You can then navigate up and down the tree as needs be using the following type syntaxes:

根据数据绑定概述，您可以使用“/”来指示当前项目。然后，您可以根据需要使用以下类型语法在树中上下导航：

<Button Content="{Binding }" />
<Button Content="{Binding Path=/}" />
<Button Content="{Binding Path=/Description}" />

Have you tried using the RelativeSource markup extension? You can use Self there.

您是否尝试过使用RelativeSource标记扩展？你可以在那里使用Self。
