Параметры

nodesToSearch
Тип: System.Windows.Ink.ContextNodeCollection
The collection of ContextNode objects that comprise the text range.

start
Тип: System.Int32%
When this method returns, the start parameter contains a 32-bit signed integer that indicates the start of the text range. This parameter is uninitialized when it is passed in.

length
Тип: System.Int32%
When this method returns, the length parameter contains a 32-bit signed integer that indicates the length of the text range. This parameter is uninitialized when it is passed in.

Заметки

If nodesToSearch contains ContextNode objects that are not adjacent to each other, this method returns the smallest text range that covers all of the ContextNode objects.

This method throws a ArgumentException when nodesToSearch contains a ContextNode that is not associated with the InkAnalyzer.

Примеры

This example defines a method named SelectTextRangeFromNodes that sets the text of the TextBox (named theResultsTextBox) to the recognition string of the InkAnalyzer (named theInkAnalyzer). It then sets the text box selection to span the recognized text for the parameter, theContextNodes.

Private Sub SelectTextRangeFromNodes(ByVal theContextNodes As ContextNodeCollection) 

    ' Set the text of theResultsTextBox.
    Me.theResultsTextBox.Text = Me.theInkAnalyzer.GetRecognizedString()

    ' Get the text range for theContextNodes.
    Dim theStart As Integer
    Dim theLength As Integer

    Me.theInkAnalyzer.GetTextRangeFromNodes(theContextNodes, theStart, theLength)

    ' Select the text range in the TextBox.
    Me.theResultsTextBox.Select(theStart, theLength)

End Sub 'SelectTextRangeFromNodes

private void SelectTextRangeFromNodes(ContextNodeCollection theContextNodes)
{
    // Set the text of theResultsTextBox.
    this.theResultsTextBox.Text = this.theInkAnalyzer.GetRecognizedString();

    // Get the text range for theContextNodes.
    int theStart;
    int theLength;

    this.theInkAnalyzer.GetTextRangeFromNodes(
        theContextNodes, out theStart, out theLength);

    // Select the text range in the TextBox.
    this.theResultsTextBox.Select(theStart, theLength);
}
