XML:

<DLC>
    <ObjectClass>RVM_GWR_Class166_DMSL_C</ObjectClass>
    <ShortName>Class166</ShortName>
</DLC>
<DLC>
    <ObjectClass>RVM_BR_Class170_DMCL_W_C</ObjectClass>
    <ShortName>Class170</ShortName>
</DLC>

Previous code:

var values = xml.Descendants("DLC")
    .Where(i => i.Element("ObjectClass").Value == locoName)
    .Select(DLC => new
    {
        ShortName = (string)DLC.Element("ShortName"),
        DisplayName = (string)DLC.Element("DisplayName"),
    });

Currently, the code works by checking whether the locoName string matches the ObjectClass XML element.

But what I really need to do is something like this:

.Where(locoName.Contains(i => i.Element("ShortName").Value))

The above does not compile due to:

Cannot convert lambda expression to type ‘string’ because it is not a delegate type

I need to make a match where the locoName string contains the ShortName XML Element.

The locoName will be something like this: “RVM_GWR_Class166_Z_ABC123” ie; the Class166 part will match.

I can’t quite work out how to do that in LINQ.
