AttributeInfo.Name

**Name** As `String</api/data_types/string>`

> This property is read-only.
>
> This code gets the list of properties for the passed type instance.

AttributeInfo.Value

**Value** As `Variant</api/data_types/variant>`

> The optional value of the attribute.
>
> This property is read-only.

## Notes

For attributes of classes, attributes are inherited from the parent class and attribute values are overridden if redefined by the subclass.

Add attributes to project items, methods, properties, constants, etc. by using the "Advanced" tab on the Inspector.

## Sample code

Suppose Window1 has three attributes: The first attribute contains the Name only and the others have both a Name and Value:

| Name    | Value |
|---------|-------|
| myName1 |       |
| myName2 | "Foo" |
| myName3 | 23    |

The following code retrieves the attributes and displays them in a `ListBox</api/user_interface/desktop/desktoplistbox>`:

``` xojo
For Each attribute As Introspection.AttributeInfo In Introspection.GetType(window1).GetAttributes
  ListBox1.AddRow(attribute.Name)
  If attribute.Value.IsNull Then
    ListBox1.CellTextAt(ListBox1.LastAddedRowIndex,1) = "No Value"
  Else
    ListBox1.CellTextAt(ListBox1.LastAddedRowIndex,1) = attribute.Value
  End If
Next
```
