示例2: GetRangeFromChild

/// -------------------------------------------------------------------
/// <summary>
/// Obtains a text range spanning an embedded child 
/// of a document control and displays the content of the range.
/// </summary>
/// <param name="targetTextElement">
/// The AutomationElment that represents a text control.
/// </param>
/// -------------------------------------------------------------------

        targetTextElement.GetCurrentPattern(TextPattern.Pattern)
        as TextPattern;

    if (textPattern == null)
    {
        // Target control doesn't support TextPattern.
        return;
    }

    // Obtain a text range spanning the entire document.
    TextPatternRange textRange = textPattern.DocumentRange;

    // Retrieve the embedded objects within the range.
    AutomationElement[] embeddedObjects = textRange.GetChildren();

    // Retrieve and display text value of embedded object.
    foreach (AutomationElement embeddedObject in embeddedObjects)
    {
        if ((bool)embeddedObject.GetCurrentPropertyValue(
            AutomationElement.IsTextPatternAvailableProperty))
        {
           // For full functionality a secondary TextPattern should
           // be obtained from the embedded object.
           // embeddedObject must be a child of the text provider.
            TextPatternRange embeddedObjectRange =
                textPattern.RangeFromChild(embeddedObject);
            // GetText(-1) retrieves all text in the range.
            // Typically a more limited amount of text would be 
            // retrieved for performance and security reasons.
            Console.WriteLine(embeddedObjectRange.GetText(-1));
        }
    }
