2008-10-28

子 ContextNodeBase オブジェクトを削除します。

名前空間 : System.Windows.Ink.AnalysisCore
アセンブリ : IACore (IACore.dll 内)

構文

'宣言
Public Sub DeleteSubNode ( _
    node As ContextNodeBase _
)
'使用
Dim instance As ContextNodeBase
Dim node As ContextNodeBase

instance.DeleteSubNode(node)

public void DeleteSubNode(
    ContextNodeBase node
)

public:
void DeleteSubNode(
    ContextNodeBase^ node
)

public void DeleteSubNode(
    ContextNodeBase node
)

public function DeleteSubNode(
    node : ContextNodeBase
)

パラメータ

node
型 : System.Windows.Ink.AnalysisCore.ContextNodeBase
削除する ContextNodeBase。

解説

ノードが空でない場合は、例外がスローされます。node がこの ContextNodeBase オブジェクトの子でない場合は、ArgumentException がスローされます。

例

この例では、すべての行を独自の段落に配置します。theInkAnalyzerBase; という名前の InkAnalyzerBase の行を使用することにより、行ごとに新しい段落サブノードを作成し、行の親をそれらの新しい段落に設定し、元の段落を削除します。
