Remarks

The query extension methods defined in this class are designed to take the place of recursive searches of D8Lits. Query extension methods return LINQ friendly enumerable lists intended to replace recursive methods used to identify child nodes in a D8 list.

Example

The following example illustrates a query which will return all work locations in the design tab.

// Find all work locations in the design tree using the find method.
public List<ID8ListItem> FindWorkLocations()
{
    var designerTopLevel = (ID8List)DesignerTopLevel.Instance;
            
    return (designerTopLevel).Query(item => item is ID8WorkLocation).ToList();
