D8ListQueryExtensions Class

Extension methods for the ID8List interface that perform recursive searches D8 tree nodes.

Object Model

Syntax

Visual Basic
C#

'Declaration
 
<ExtensionAttribute()>
Public MustInherit NotInheritable Class D8ListQueryExtensions

'Usage
 
Dim instance As D8ListQueryExtensions

[Extension()]
public static class D8ListQueryExtensions

Remarks

The query extension methods defined in this class are designed to take the place of recursive searches of D8Lists. 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();
}
