通过代码隐藏在WPF访问资源 [英] Accessing a resource via codebehind in WPF

问题描述

我有如下我的窗口资源定义的自定义集合（在SketchFlow的应用程序，以便该窗口实际上是一个用户控件）：

I have a custom collection defined in my window resources as follows (in a Sketchflow app so the window is actually a UserControl):

<UserControl.Resources>
    <ds:MyCollection x:Key="myKey" x:Name="myName" />
</UserControl.Resources>

我希望能够引用这个集合中的代码隐藏，我预计会是由X：名称，但我似乎无法访问它。

I want to be able to refer to this collection in the codebehind, which I expected would be by the x:Name, but I can't seem to access it.

我可以使用

myRef = (MyCollection) this.FindName("myKey");

但这似乎的hackish。这是不好的做法，什么会更好？谢谢。）

but this seems hackish. Is this bad practice, and what would be better? Thanks :)

推荐答案

您应该使用FindResource或TryFindResource

You should use FindResource or TryFindResource.

此外，一个好的做法是创建一个字符串常量将映射在资源字典的键的名称（这样就可以只在一个地方改变它）

Also, a good practice is to create a string constant which maps the name of your key in the resource dictionary (so that you can change it at only one place)
