Dim instance As ContextNode
Dim returnValue As String

returnValue = instance.ToString

public override string ToString ()

Return Value

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".

Example

This example is a method that recursively traverses a tree of ContextNode objects. It uses the SubNodes property and populates a System.Windows.Forms.TreeViewSystem.Windows.Forms.TreeView by adding TreeNodeTreeNode objects. It then sets their TreeNode.TextTreeNode.Text property to ToString, adding InkWordNode.GetRecognizedString or InkDrawingNode.GetShapeName if appropriate.
