示例1: PropertyCondition
' Set up the conditions for finding the text control.
Dim documentControl As New PropertyCondition( _
AutomationElement.ControlTypeProperty, ControlType.Document)
Dim textPatternAvailable As New PropertyCondition( _
AutomationElement.IsTextPatternAvailableProperty, True)
Dim findControl As New AndCondition(documentControl, textPatternAvailable)
' Get the Automation Element for the first text control found.
' For the purposes of this sample it is sufficient to find the
' first text control. In other cases there may be multiple text
' controls to sort through.
targetDocument = targetWindow.FindFirst(TreeScope.Descendants, findControl)
' Didn't find a text control.
If targetDocument Is Nothing Then
targetResult.Content = _
WPFTarget + " does not contain a Document control type."
targetResult.Background = Brushes.Salmon
startWPFTargetButton.IsEnabled = False
Return
End If
' Get required control patterns
targetTextPattern = DirectCast( _
targetDocument.GetCurrentPattern(TextPattern.Pattern), TextPattern)
' Didn't find a text control that supports TextPattern.
If targetTextPattern Is Nothing Then
targetResult.Content = WPFTarget + _
" does not contain an element that supports TextPattern."
targetResult.Background = Brushes.Salmon
startWPFTargetButton.IsEnabled = False

End If
