void InsertIntoCollectionAt(IXamlDirectObject const& xamlDirectObject, uint32_t const& index, IXamlDirectObject const& value);
public void InsertIntoCollectionAt(IXamlDirectObject xamlDirectObject, uint index, IXamlDirectObject value);
function insertIntoCollectionAt(xamlDirectObject, index, value)
Public Sub InsertIntoCollectionAt (xamlDirectObject As IXamlDirectObject, index As UInteger, value As IXamlDirectObject)

參數

xamlDirectObject
IXamlDirectObject

參考特定的 IXamlDirectObject 集合。

index
UInt32

unsigned int

uint32_t

參考集合中必須插入指定值的索引。

value

範例

下列範例示範如何使用 XamlDirect API，將值插入集合中的特定索引。

XamlDirect xd = XamlDirect.GetDefault();

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

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

IXamlDirectObject button = xd.CreateInstance(XamlTypeIndex.Button);
xd.InsertIntoCollectionAt(childrenCollection, 0, button);

XamlDirect^ xd = XamlDirect::GetDefault();

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

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

IXamlDirectObject^ button = xd->CreateInstance(XamlTypeIndex::Button);
xd->InsertIntoCollectionAt(childrenCollection, 0, button);
