在WPF中使用Value Converters，而不必首先将它们定义为资源

问题描述

是否可以使用价值转换器而不必事先将其定义为资源？

Is it possible to use value converters without having to define them beforehand as resources?

现在我有

<Window.Resources>
    <local:TrivialFormatter x:Key="trivialFormatter" />
</Window.Resources>

和

<Button Width="{Binding Width, ElementName=textBox1, UpdateSourceTrigger=PropertyChanged, Converter={StaticResource trivialFormatter}}" Height="50">

不可能，而不是在Window.Resources中声明trivialFormatter资源，我可以直接从Button的宽度绑定中引用它？像

Wouldn't it be possible that instead of having to declare the trivialFormatter resource in Window.Resources, I could directly refer it from the Button's width binding? Something like

Converter = {local:TrivialFormatter}

谢谢

推荐答案

在单例型 IValueConverter s（例如，他们不需要任何来自当前绑定实例的状态）我使用静态转换器，即：

In the case of singleton-type IValueConverters (e.g. they don't need any state from the current binding instance) I use static converters, i.e.:

Converter={x:Static SomeNamespace:SomeConverter.Instance}

还有一个WPF博士发表了伟大的发言，使用标记扩展名使其更清晰的内嵌。

There's also a great post by Dr. WPF on using a markup extension to make it cleaner inline here.
