c# - Cannot compile project when declaring a XAML Resource Dictionary in code -

i've got resource dictionary called editorresources.xaml , contains following code:

<resourcedictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"                     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"                     xmlns:editors="clr-namespace:mycompany.editors">      <datatemplate x:key="passwordeditordatatemplate">     </datatemplate> </resourcedictionary> 

but when include line of code in class:

private editorresources res = new editorresources(); 

it doesn't compile project. doesn't display errors list view in .net ide when @ output view, displays following error:

error cs0246: type or namespace name 'editorresources' not found (are missing using directive or assembly reference?)

but, don't believe reference missing both resource dictionary , class in same project (same level) , can see editorresources type highlighted type , intellisense kicks in expected when hit '.' key , displays properties relevant resource dictionary i.e. .mergedictionaries, etc...

update:

if me, you've stored resource dictionary (editorresources.xaml) in sub-folder (editors), , assembly called 'mycompany.activity.shared' example, don't forget include sub-folder in component's part when call code provided @drewnoakes, can call following without problems:

var res = new resourcedictionary {    source = new uri("/mycompany.activity.shared;component/editors/editorresources.xaml",    urikind.relativeorabsolute) }; 

once have object, can access datatemplates or other via code.

seems have editorresources.xaml file not corresponding editorresources.xaml.cs file.

in case, type xaml file defines resourcedictionary. if wish have subclass of that, need define partial backing class , add relevant attributes in xaml link them together.

if don't need c# code behind scenes, load resourcedictionary directly.

some code might help:

var dict = new resourcedictionary {     source = new uri("/yourassemblyname;component/editorresources.xaml",                      urikind.relativeorabsolute) }
