FindResource在Window.Resources

Question

我在XAML中聲明，像這樣的資源：

<Window x:Class="Test.MainWindow" 
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
    xmlns:local="clr-namespace:Test" 
    Title="MainWindow" Height="350" Width="525" Name="form1"> 
    <Window.Resources> 
    <ObjectDataProvider x:Key="SingleRole" ObjectType="{x:Type local:SingleRole}" /> 
    </Window.Resources> 
... 
</Window> 

我試圖讓在代碼中對象的引用：

private void button1_Click_1(object sender, RoutedEventArgs e) 
    { 
     SingleRole role = ????; 
    } 

哪有我這樣做？我已經嘗試過FindResource和this.Resources [「SingleRole」]，但我似乎無法讓它工作。

Answer 1

您應該能夠使用this.Resources與投：

var provider = (ObjectDataProvider)this.Resources["SingleRole"]; 
SingleRole role = provider.ObjectInstance as SingleRole; 
if (role != null) 
{ 
    // Use it here, as it was found properly 
} 

Answer 2

這應該工作 -

var a = this.FindResource("SingleRole");
