發行項
10/29/2008

建立新的子 ContextNodeBase 物件。

命名空間： System.Windows.Ink.AnalysisCore
組件： IACore (在 IACore.dll 中)

語法

'宣告
Public Function CreateSubNode ( _
    type As Guid _
) As ContextNodeBase
'用途
Dim instance As ContextNodeBase
Dim type As Guid
Dim returnValue As ContextNodeBase

returnValue = instance.CreateSubNode(type)

public ContextNodeBase CreateSubNode(
    Guid type
)

public:
ContextNodeBase^ CreateSubNode(
    Guid type
)

public ContextNodeBase CreateSubNode(
    Guid type
)

public function CreateSubNode(
    type : Guid
) : ContextNodeBase

參數

type
型別：System.Guid
要建立的內容節點類型。使用 ContextNodeTypeBase 類別中定義的其中一個 GUID，即可指定要建立的型別。

傳回值

型別：System.Windows.Ink.AnalysisCore.ContextNodeBase
新建立的 ContextNodeBase 物件，其父代 (Parent) 是這個 ContextNodeBase。

備註

當現有的子節點已經存在時，會加入新建立的 ContextNodeBase 做為 SubNodes 集合中的最後一個子節點。

範例

這個範例會取得所有行，並且將它們放入本身所屬的段落中。範例中會使用來自 InkAnalyzerBasetheInkAnalyzerBase; 的行，為每一行建立新的段落子節點，並且將這些行的父代重設為這些新段落。
