'使用
Dim instance As ContextNodeBase
Dim value As Guid

value = instance.Type

public Guid Type { get; }

プロパティ値

型 : System.Guid

例

次の例では、selectedNode という名前の ContextNodeBase オブジェクトの Type プロパティを使用する方法を示します。TextBox、selectedResultsTextBox のテキストは、ノードの種類に従って別に書き込まれます。ほとんどの場合、認識された文字列が使用されますが、InkWord の場合は行の認識された文字列が使用され、単語は TextBox で選択されます。
