示例1: TextFromSelection
Private Function TextFromSelection(ByVal target As AutomationElement, ByVal length As Int32) As String
' Specify the control type we're looking for, in this case 'Document'
Dim cond As PropertyCondition = New PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Document)
' target --> The root AutomationElement.
Dim textProvider As AutomationElement = target.FindFirst(TreeScope.Descendants, cond)
Dim textpatternPattern As TextPattern = CType(textProvider.GetCurrentPattern(TextPattern.Pattern), TextPattern)
If (textpatternPattern Is Nothing) Then
Console.WriteLine("Root element does not contain a descendant that supports TextPattern.")
Return Nothing
End If
Dim currentSelection As TextPatternRange() = textpatternPattern.GetSelection()
' GetText(-1) retrieves all characters but can be inefficient
Return currentSelection(0).GetText(length)
End Function
