ContextNode.ToString 方法
以字串的形式傳回 ContextNode 物件的型別,這個型別是人們可讀取的 (Human-Readable) 型別。
命名空間: System.Windows.Ink
組件: IAWinFX (在 IAWinFX.dll 中)
語法
'宣告
Public Overrides Function ToString As String
'用途
Dim instance As ContextNode
Dim returnValue As String
returnValue = instance.ToString()
public override string ToString()

public override function ToString() : String
傳回值
型別:System.String
ContextNode 物件的型別,這個型別是人們可讀取的字串型別。
備註
例如,Type 是 InkWord,則這個方法會傳回 "InkWordNode" 這個值。
範例
這個範例是一個方法,會遞迴地周遊 ContextNode 物件的樹狀目錄。它會使用 SubNodes 屬性,並藉由加入 TreeViewItem 物件來填入 TreeView。然後將物件的 Header 屬性設定為 ToString,並加入 InkWordNode.GetRecognizedString 或 InkDrawingNode.GetShapeName (如果適用的話)。
Private Shared Sub WalkTree(ByVal parentContextNode As ContextNode, ByVal parentTreeNode As TreeViewItem)
parentTreeNode.IsExpanded = True
For Each theContextSubnode As ContextNode In parentContextNode.SubNodes
Dim newTreeNode As New TreeViewItem()
newTreeNode.Header = theContextSubnode.ToString()
If TypeOf theContextSubnode Is InkWordNode Then
newTreeNode.Header += ": " + CType(theContextSubnode, InkWordNode).GetRecognizedString()
ElseIf TypeOf theContextSubnode Is InkDrawingNode Then
newTreeNode.Header += ": " + CType(theContextSubnode, InkDrawingNode).GetShapeName()
End If
' If the context node is confirmed, add a note to the
' tree view item.
If (theContextSubnode.IsConfirmed(ConfirmationType.NodeTypeAndProperties)) Then
newTreeNode.Header += " Confirmed."
End If
' Add the context node as a tag of the tree view item and
' add the new tree view item to the parent node.
newTreeNode.Tag = theContextSubnode
parentTreeNode.Items.Add(newTreeNode)
WalkTree(theContextSubnode, newTreeNode)
Next theContextSubnode
End Sub 'WalkTree
private static void WalkTree(ContextNode parentContextNode, TreeViewItem parentTreeNode)
{
// Expand the current TreeViewItem.
parentTreeNode.IsExpanded = true;
foreach (ContextNode theContextSubnode
in parentContextNode.SubNodes)
{
TreeViewItem newTreeNode = new TreeViewItem();
newTreeNode.Header = theContextSubnode.ToString();
if (theContextSubnode is InkWordNode)
{
newTreeNode.Header += ": " +
((InkWordNode)theContextSubnode).GetRecognizedString();
}
else if (theContextSubnode is InkDrawingNode)
{
newTreeNode.Header += ": " +
((InkDrawingNode)theContextSubnode).GetShapeName();
}
// If the context node is confirmed, add a note to the
// tree view item.
if (theContextSubnode.IsConfirmed(ConfirmationType.NodeTypeAndProperties))
{
newTreeNode.Header += " Confirmed.";
}
// Add the context node as a tag of the tree view item and
// add the new tree view item to the parent node.
newTreeNode.Tag = theContextSubnode;
parentTreeNode.Items.Add(newTreeNode);
WalkTree(theContextSubnode, newTreeNode);
