範例
下列範例示範如何在集合的指定索引處存取 IXamlDirectObject 專案。
XamlDirect xd = XamlDirect.GetDefault();
IXamlDirectObject relativePanel = xd.CreateInstance(XamlTypeIndex.RelativePanel);
IXamlDirectObject childrenCollection = xd.GetXamlDirectObjectProperty(relativePanel, XamlPropertyIndex.Panel_Children);
IXamlDirectObject first = xd.GetXamlDirectObjectFromCollectionAt(childrenCollection, 0);
XamlDirect^ xd = XamlDirect::GetDefault();
IXamlDirectObject^ relativePanel = xd->CreateInstance(XamlTypeIndex::RelativePanel);
IXamlDirectObject^ childrenCollection = xd->GetXamlDirectObjectProperty(relativePanel, XamlPropertyIndex::Panel_Children);
IXamlDirectObject^ first = xd->GetXamlDirectObjectFromCollectionAt(childrenCollection, 0);
