示例1: StringBuilder
' This method will extract and return a string that contains a representation of
' the XAML structure of content elements in a given TextElement.
Private Function GetXaml_Renamed(ByVal element As TextElement) As String
Dim buffer As New StringBuilder()
' Position a "navigator" pointer before the opening tag of the element.
Dim navigator As TextPointer = element.ElementStart
Do While navigator.CompareTo(element.ElementEnd) < 0
Select Case navigator.GetPointerContext(LogicalDirection.Forward)
Case TextPointerContext.ElementStart
' Output opening tag of a TextElement
buffer.AppendFormat("<{0}>", navigator.GetAdjacentElement(LogicalDirection.Forward).GetType().Name)
Case TextPointerContext.ElementEnd
' Output closing tag of a TextElement
buffer.AppendFormat("</{0}>", navigator.GetAdjacentElement(LogicalDirection.Forward).GetType().Name)
Case TextPointerContext.EmbeddedElement
' Output simple tag for embedded element
buffer.AppendFormat("<{0}/>", navigator.GetAdjacentElement(LogicalDirection.Forward).GetType().Name)
Case TextPointerContext.Text
' Output the text content of this text run
buffer.Append(navigator.GetTextInRun(LogicalDirection.Forward))
End Select
' Advance the naviagtor to the next context position.
navigator = navigator.GetNextContextPosition(LogicalDirection.Forward)
Loop ' End while.
Return buffer.ToString()
End Function ' End GetXaml method.
