如何在 ResourceDictionary 文件中引用转换器

Question

我正在尝试创建一个资源字典文件并引用一个值转换器。如何做到这一点？

<ResourceDictionary xmlns="http://xamarin.com/schemas/2014/forms" 
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:converters="clr-namespace:CS.Runtime.Crew.Converters"               
x:Class="CS.Runtime.Crew.Resources.CrewResourceDictionary" >

<ResourceDictionary.MergedDictionaries>
    <ResourceDictionary>
        <!--<converters:DateTimeToNullableDateTimeConverter x:Key="DateTimeToNullableDateTimeConverter" />-->
    </ResourceDictionary>
</ResourceDictionary.MergedDictionaries>

<DataTemplate x:Key="workGroupAttributesTemplate">
    <Grid>
<controls:ExtendedDatePicker NullableDate="{Binding Attributes[DueDate], Converter={StaticResource DateTimeToNullableDateTimeConverter}}" Grid.Column="1" Grid.Row="4" />
    </Grid>
</DataTemplate>
</ResourceDictionary>

Answer 1

首先添加class 命名空间

我们假设 class 是 Checker 并且 checker 是命名空间

标题

xmlns:checker="clr-namespace:Something.Checker;assembly=Something

身体

<checker:MySpecialValueConverter x:Key="MySpecialValue"/>
