語法
'宣告
Public Sub DeleteSubNode ( _
node As ContextNodeBase _
)
'用途
Dim instance As ContextNodeBase
Dim node As ContextNodeBase
instance.DeleteSubNode(node)
public void DeleteSubNode(
ContextNodeBase node
)
public:
void DeleteSubNode(
ContextNodeBase^ node
)
public void DeleteSubNode(

參數
備註
如果節點不是空的，則會擲回例外狀況。如果 node 不是這個 ContextNodeBase 物件的子系，則會擲回 ArgumentException。
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 InkAnalyzerBase (名為 theInkAnalyzerBase;) 的行，為每一行建立新的段落子節點、將這些行的父代重設為這些新段落，並且刪除原始段落。
