Accessing DataTemplate from ResourceDictionary in code behind

Question

I am trying to convert a vendor provided VB solution to C#. I need to load a DataTemplate from a custom ResourceDictionary XAML into a c# class. I cannot determine how to get the DataTemplate. I am able to create a ResourceDictionary and load the XAML but am stumped from there. Here is my XAML [EditorResources].

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:PropertyEditing="clr-namespace:Microsoft.Windows.Design.PropertyEditing;assembly=Microsoft.Windows.Design.Interaction"
                    xmlns:Local="clr-namespace:MyControls.Design"
                    xmlns:my="clr-namespace:MyControls;assembly=MyControls"
                    x:Class="EditorResources">
    <DataTemplate x:Key="TagBrowserInlineEditorTemplate">
        <Grid>
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="1*"/>
                <ColumnDefinition Width="Auto"/>
            </Grid.ColumnDefinitions>
            <TextBox Grid.Column="0" Text="{Binding StringValue}"/>
            <PropertyEditing:EditModeSwitchButton Grid.Column="1"/>
        </Grid>
    </DataTemplate>

    <DataTemplate x:Key="template">
        <Border BorderThickness="2" 
                BorderBrush="Black">
            <TextBlock Text="{Binding Path=value}" Padding="2" />
        </Border>
    </DataTemplate>

</ResourceDictionary>

Here is the VB code that I need to convert:

Imports System
Imports System.ComponentModel
Imports System.Windows
Imports Microsoft.Windows.Design.Metadata
Imports Microsoft.Windows.Design.PropertyEditing
Imports Microsoft.Win32

Public Class TagBrowserDialogPropertyValueEditor
    Inherits DialogPropertyValueEditor
    Private res As New EditorResources()

    Public Sub New()
        Me.InlineEditorTemplate = TryCast(res("TagBrowserInlineEditorTemplate"), DataTemplate)
    End Sub

    Public Overloads Overrides Sub ShowDialog(ByVal propertyValue As PropertyValue, ByVal commandSource As IInputElement)
        Dim frmBrowseTagParameter As New OPCWPFDashboard.Design.FormBrowseTagParameter
        If frmBrowseTagParameter Is Nothing Then
            frmBrowseTagParameter = New OPCWPFDashboard.Design.FormBrowseTagParameter
        End If

        If frmBrowseTagParameter.ShowDialog = Forms.DialogResult.OK Then
            propertyValue.StringValue = frmBrowseTagParameter.Final_Tag
        End If

    End Sub


End Class

As far as I understand, res variable is the instance of the class derived from ResourceDictionary. In this case you can get the data template very easy:

this.InlineEditorTemplate = res["TagBrowserInlineEditorTemplate"] as DataTemplate;
