範例

下列範例示範如何透過IXamlDirectObject的 實例取得Panel.Children的計數。

XamlDirect xd = XamlDirect.GetDefault();

IXamlDirectObject relativePanel = xd.CreateInstance(XamlTypeIndex.RelativePanel);

IXamlDirectObject childrenCollection = xd.GetXamlDirectObjectProperty(relativePanel, XamlPropertyIndex.Panel_Children);

uint count = xd.GetCollectionCount(childrenCollection);

XamlDirect^ xd = XamlDirect::GetDefault();

IXamlDirectObject^ relativePanel = xd->CreateInstance(XamlTypeIndex::RelativePanel);

IXamlDirectObject^ childrenCollection = xd->GetXamlDirectObjectProperty(relativePanel, XamlPropertyIndex::Panel_Children);

UINT count = xd->GetCollectionCount(childrenCollection);
