ContextNodeBase.ToString 方法

傳回人們可讀取的 (Human-Readable) ContextNodeBase 物件字串型別。

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

語法

'宣告
Public Overrides Function ToString As String
'用途
Dim instance As ContextNodeBase
Dim returnValue As String

returnValue = instance.ToString()

public override string ToString()

public:
virtual String^ ToString() override

public String ToString()

public override function ToString() : String

傳回值

型別：System.String
人們可讀取的 ContextNodeBase 物件字串型別。

備註

例如，如果 Type 是 InkWord，則這個方法會傳回值 "InkWordNode"。

範例

這個範例是一個方法，會遞迴地周遊 ContextNodeBase 物件的樹狀目錄。它會使用 SubNodes 屬性，並且透過加入 TreeNode 物件填入 System.Windows.Forms.TreeView。然後將 Text 屬性設定為 ToString，加入已辨識的字串或圖案名稱 (如果適用的話)。

Private Sub WalkTree(ByVal parentContextNode As ContextNodeBase, ByVal parentTreeNode As TreeNode)

    Dim cNode As ContextNodeBase

    For Each cNode In parentContextNode.SubNodes

        Dim newTNode As New TreeNode(cNode.ToString())

        If cNode.Type = System.Windows.Ink.AnalysisCore.ContextNodeTypeBase.InkWord AndAlso _
           cNode.ContainsPropertyData(PropertyGuidsForContextNodesBase.RecognizedString) Then

            newTNode.Text = newTNode.Text + _
                ": " + CType(cNode.GetPropertyData(PropertyGuidsForContextNodesBase.RecognizedString), _
                String)

        ElseIf cNode.Type = System.Windows.Ink.AnalysisCore.ContextNodeTypeBase.InkDrawing AndAlso _
