StackTrace-Konstruktor (Boolean)

Initialisiert eine neue Instanz der StackTrace-Klasse aus dem Rahmen des Aufrufers und zeichnet bei Bedarf Quellinformationen auf.

Namespace: System.Diagnostics
Assembly: mscorlib (in mscorlib.dll)

Syntax

'Declaration
Public Sub New ( _
    fNeedFileInfo As Boolean _
)
'Usage
Dim fNeedFileInfo As Boolean

Dim instance As New StackTrace(fNeedFileInfo)

public StackTrace (
    bool fNeedFileInfo
)

public:
StackTrace (
    bool fNeedFileInfo
)

public StackTrace (
    boolean fNeedFileInfo
)

public function StackTrace (
    fNeedFileInfo : boolean
)

Parameter

• fNeedFileInfo
  true, wenn Dateiname, Zeilennummer und Spaltennummer aufgezeichnet werden sollen, andernfalls false.

Hinweise

StackTrace wird mit dem aktuellen Thread des Aufrufers erstellt.

Beispiel

Im folgenden Codebeispiel werden verschiedene StackTrace-Konstruktormethoden veranschaulicht.

Public Sub Level2Method()
   Try
      Dim nestedClass As New ClassLevel3
      nestedClass.Level3Method()
   
   Catch e As Exception
      Console.WriteLine(" Level2Method exception handler")
      
      ' Display the full call stack at this level.
      Dim st1 As New StackTrace(True)
      Console.WriteLine(" Stack trace for this level: {0}", _
         st1.ToString())
      
      ' Build a stack trace from one frame, skipping the current
      ' frame and using the next frame.
      Dim st2 As New StackTrace(New StackFrame(1, True))
