ContextNodeBase.DeleteSubNode 方法
删除一个子 ContextNodeBase 对象。
命名空间： System.Windows.Ink.AnalysisCore
程序集： IACore（在 IACore.dll 中）
语法
声明
Public Sub DeleteSubNode ( _
node As ContextNodeBase _
)
用法
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
)
参数
备注
如果节点不为空，则引发异常。如果 node 不是此 ContextNodeBase 对象的子级，则引发 ArgumentException。
示例
此示例获取所有行，并将这些行放入各自的段落中。它使用名为 theInkAnalyzerBase 的 InkAnalyzerBase 中的行，为每一行新建一个段落子节点，将这些行的父级重新设置为这些新段落，然后删除原来的段落。
