範例

以下範例取得該屬性的當前值。 若元素未提供預設值，則回傳預設值。

ControlType controlTypeId =

    as ControlType;

Dim controlTypeId As ControlType = _
  DirectCast(autoElement.GetCurrentPropertyValue(AutomationElement.ControlTypeProperty), ControlType)

以下範例取得該屬性的當前值，但指定若元素本身未提供屬性值， NotSupported 則回傳該屬性而非預設值。

ControlType controlTypeId1;
object controlTypeNoDefault =
    autoElement.GetCurrentPropertyValue(AutomationElement.ControlTypeProperty, true);
if (controlTypeNoDefault == AutomationElement.NotSupported)
{
    // TODO Handle the case where you do not wish to proceed using the default value.
}
else  
{
    controlTypeId1 = controlTypeNoDefault as ControlType;
}

Dim controlTypeId1 As ControlType
Dim controlTypeNoDefault As Object = _
    autoElement.GetCurrentPropertyValue(AutomationElement.ControlTypeProperty, True)
If controlTypeNoDefault Is AutomationElement.NotSupported Then
    ' TODO Handle the case where you do not wish to proceed using the default value.
Else
    controlTypeId1 = DirectCast(controlTypeNoDefault, ControlType)
End If
