Beispiel

Im folgenden Codebeispiel wird eine Verwendungsmöglichkeit eines StackFrame-Konstruktors veranschaulicht.

Public Sub InternalMethod()
   Try
      Dim nestedClass As New ClassLevel2
      nestedClass.Level2Method()
   Catch e As Exception
      Console.WriteLine(" InternalMethod exception handler")
      
      ' Build a stack trace from one frame, skipping the 
      ' current frame and using the next frame.  By default,
      ' file and line information are not displayed.
      Dim st As New StackTrace(New StackFrame(1))
      Console.WriteLine(" Stack trace for next level frame: {0}", _
         st.ToString())
      Console.WriteLine(" Stack frame for next level: ")
      Console.WriteLine("   {0}", st.GetFrame(0).ToString())
