Setting the Style property of a WPF Label in code?
提问by Daniel
In App.xaml, I have the following code:
在 App.xaml 中，我有以下代码：
<Application.Resources>
<Style x:Key="LabelTemplate" TargetType="{x:Type Label}">
<Setter Property="Height" Value="53" />
<Setter Property="Width" Value="130" />
<Setter Property="HorizontalAlignment" Value="Left" />
<Setter Property="Margin" Value="99,71,0,0" />
<Setter Property="VerticalAlignment" Value= "Top" />
<Setter Property="Foreground" Value="#FFE75959" />
<Setter Property="FontFamily" Value="Calibri" />
<Setter Property="FontSize" Value="40" />
</Style>
</Application.Resources>
This is meant to provide a generic template for my labels.
这是为了为我的标签提供通用模板。
In the main XAML code, I have the following line of code:
在主要的 XAML 代码中，我有以下代码行：
<Label Content="Movies" Style="{StaticResource LabelTemplate}" Name="label1" />
However, I'd like to initialize the Style property through code. I have tried:
但是，我想通过代码初始化 Style 属性。我试过了：
label1.Style = new Style("{StaticResource LabelTemplate}");
and
和
label1.Style = "{StaticResource LabelTemplate}";
Neither solution was valid.
两种解决方案都无效。
Any help would be appreciated :).
任何帮助，将不胜感激 ：）。

Where in code are you trying to get the style? Code behind?
您试图在代码中的何处获得样式？后面的代码？
You should write this:
你应该这样写：
If you're in code-behind:
如果您处于代码隐藏状态：
Style style = this.FindResource("LabelTemplate") as Style;
label1.Style = style;
If you're somewhere else
如果你在别处
Style style = Application.Current.FindResource("LabelTemplate") as Style;
label1.Style = style;
Bottom note:don't name a Stylewith the keyword Template, you'll eventually end up confusing a Styleand a Template, and you shouldn't as those are two different concepts.
底注：不要Style用关键字命名 a Template，你最终会混淆 aStyle和 a Template，你不应该因为它们是两个不同的概念。

Please check for null style result or you will be sad... ... if (style != null) this.Style = style;
请检查空样式结果，否则您会感到难过... ... if (style != null) this.Style = style;

Maybe an old question, but if you are trying W10 UWP app must use resources collection of each object or resources collection of Application object
也许是一个老问题，但如果你正在尝试 W10 UWP 应用程序必须使用每个对象的资源集合或应用程序对象的资源集合
KeyValuePair<object,object> styl = this.Resources
.Where(x => x.Key.ToString() == "MyStyleTemplateName")
.FirstOrDefault();
if (styl.Value != null)
Style MyStyle = (Style)styl.Value;
Where MyStyleTemplateNamemust be defined as a resource of this
其中MyStyleTemplateName必须定义为this的资源
