Property descriptions

AttributeInfo.Name

Name As String

The name of the item. This is only the class name. To get the full namespace path, use FullName instead.

This property is read-only.

This code gets the list of properties for the passed type instance.

Var d As DateTime = DateTime.Now
For Each prop As Introspection.PropertyInfo In Introspection.GetType(d).GetProperties
  ListBox1.AddRow(prop.Name)
Next

AttributeInfo.Value

Value As 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:

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

Compatibility

All project types on all supported operating systems.
