ContextNode.ToString Method
Returns a human-readable type for the ContextNode object as a string.
Namespace: Microsoft.Ink
Assembly: Microsoft.Ink.Analysis (in Microsoft.Ink.Analysis.dll)
Syntax
'Declaration
Public Overrides Function ToString As String
'Usage
Dim instance As ContextNode
Dim returnValue As String
returnValue = instance.ToString()
public override string ToString()
public:
virtual String^ ToString() override
public override function ToString() : String
Return Value
Type: System.String
A human-readable type for the ContextNode object as a string.
Remarks
For example, if the Type is InkWord, this method returns a value of "InkWordNode".
Examples
This example is a method that recursively traverses a tree of ContextNode objects. It uses the SubNodes property and populates a System.Windows.Forms.TreeView by adding TreeNode objects. It then sets their TreeNode.Text property to ToString, adding InkWordNode.GetRecognizedString or InkDrawingNode.GetShapeName if appropriate.
