Try this....

var siteRoot = Model.Content.AncestorOrSelf(1);

var photoStaffList = (from c in siteRoot.Descendants()
                      where c.ContentType.Alias.Equals("staffProfile", StringComparison.CurrentCultureIgnoreCase)
                         && c.GetPropertyValue<String>("role").Contains("photo", StringComparison.CurrentCultureIgnoreCase)
                      select c).ToList();

Hi Ben,

Thans for the response, im getting the following compile error using your code

Thanks Paul

Going back to your original code - I think you've found a bug in how Umbraco converts the Multiple Dropdown to a string in Linq. I've just tried this and I get a similar issue.

The only workaround I can see is to get all the descendants and then test that property in a foreach loop.

You should report this as a bug I think.

My guess is that GetPropertyValue<string>("role") is returning a CSV of prevalues (e.g., "123,456,789") rather than a CSV of strings (e.g., "role1,role2,role3"). Here are some things you can do to investigate.

@{
    var nodes = siteRoot.Descendants("staffProfile").ToArray();
    var values = string.Join(" * ", nodes.Select(x => x.GetPropertyValue<string>("role")).ToArray());
}
<p>There are @(nodes.Length) nodes and the values are @(values).</p>

I'm not in an IDE right now, so I'm not sure if all that syntax is correct, but you get the idea.

Hi All,

Thanks for the responses with this one. @Nicholas i will give your solutions a go and see what i get :)

Using @Ben's posts, i can achieve what i want with the following code

//gets all the photography staff members
var photoStaffList = (from c in siteRoot.Descendants()
                      where c.ContentType.Alias.Equals("staffProfile", StringComparison.CurrentCultureIgnoreCase)
                         && c.GetPropertyValue<string>("role").ToLower().Contains("photo")
                      select c).ToList();

Be good to have a play around though.

Many thanks Paul
