範例

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

XamlDirect xd = XamlDirect.GetDefault();

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

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

uint count = xd.GetCollectionCount(childrenCollection);
XamlDirect^ xd = XamlDirect::GetDefault();

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

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

UINT count = xd->GetCollectionCount(childrenCollection);
