定义

命名空间:

Windows.UI.Xaml.Core.Direct

返回指定 IXamlDirectObject 集合中指定索引处的 IXamlDirectObject 项。

public:
 virtual IXamlDirectObject ^ GetXamlDirectObjectFromCollectionAt(IXamlDirectObject ^ xamlDirectObject, unsigned int index) = GetXamlDirectObjectFromCollectionAt;

IXamlDirectObject GetXamlDirectObjectFromCollectionAt(IXamlDirectObject const& xamlDirectObject, uint32_t const& index);

public IXamlDirectObject GetXamlDirectObjectFromCollectionAt(IXamlDirectObject xamlDirectObject, uint index);

function getXamlDirectObjectFromCollectionAt(xamlDirectObject, index)

Public Function GetXamlDirectObjectFromCollectionAt (xamlDirectObject As IXamlDirectObject, index As UInteger) As IXamlDirectObject

参数

xamlDirectObject

IXamlDirectObject

引用特定的 IXamlDirectObject 集合。

index

UInt32

unsigned int

uint32_t

引用要获取的项集合中的索引。

返回

IXamlDirectObject

返回集合的指定索引处的 IXamlDirectObject 项。

示例

以下示例演示如何访问集合的指定索引处的 IXamlDirectObject 项。

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);
