How do I reference a static resource inside a resource dictionary? [duplicate] - xaml

Question

My main resources look like this:
<?xml version="1.0" encoding="utf-8"?>
<Application xmlns:converters="clr-namespace:Japanese"
xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
x:Class="Japanese.App">
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary Source="/Resources/DetailRes.xaml" />
I have this resource file:
<?xml version="1.0" encoding="UTF-8" ?>
<ResourceDictionary xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
x:Class="Japanese.DetailRes">
<Style x:Key="DetailLabel" TargetType="Label">
<Setter Property="FontSize">
<Setter.Value>
<OnPlatform x:TypeArguments="x:Double">
<On Platform="iOS" Value="35" />
<On Platform="Android" Value="35" />
</OnPlatform>
</Setter.Value>
</Setter>
<Setter Property="VerticalOptions" Value="Center" />
<Setter Property="LineBreakMode" Value="WordWrap" />
<Setter Property="HorizontalTextAlignment" Value="Center" />
</Style>
</ResourceDictionary>
In XAML I access it like this:
<t:BaseFrameButtonTemplate xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:t="clr-namespace:Japanese.Templates"
xmlns:local="clr-namespace:Japanese;assembly=Japanese"
x:Class="Japanese.Templates.RoundButtonText" x:Name="this" >
<Label Text="{Binding Text, Source={x:Reference this}}"
Style="{StaticResource DetailRes}"
x:Name="Label" />
</t:BaseFrameButtonTemplate>
I would like to access this in C# but do not know how to do it. I tried this but it does not find the resource:
Label.Style = (Style)Application.Current.Resources["DetailRes"];

Answer 1

You can use the TryGetValue to obtain a single from your ResourceDictionary:
if (Application.Current.Resources.TryGetValue("DetailLabel", out object style))
{
someLabel.Style = (Style)style;
}
