StackFrame Constructor (Int32, Boolean)

Initializes a new instance of the StackFrame class that corresponds to a frame above the current stack frame, optionally capturing source information.

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

Syntax

Visual Basic

Public Sub New ( _
	skipFrames As Integer, _
	fNeedFileInfo As Boolean _
)

public StackFrame(
	int skipFrames,
	bool fNeedFileInfo
)

Visual C++

public:
StackFrame(
	int skipFrames, 
	bool fNeedFileInfo
)

new : 
        skipFrames:int * 
        fNeedFileInfo:bool -> StackFrame

Parameters

skipFrames: Type: System.Int32
The number of frames up the stack to skip.

fNeedFileInfo: Type: System.Boolean
true to capture the file name, line number, and column number of the stack frame; otherwise, false.

Examples

The following example demonstrates the use of the StackFrame(Int32, Boolean) constructor. This code example is part of a larger example provided for the StackFrame class.

Visual Basic


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))
      Console.WriteLine(" Stack trace built with next level frame: {0}", _
          st2.ToString())

      ' Build a stack trace skipping the current frame, and
      ' including all the other frames.
      Dim st3 As New StackTrace(1, True)
      Console.WriteLine(" Stack trace built from the next level up: {0}", _
          st3.ToString())

      Console.WriteLine()
      Console.WriteLine("   ... throwing exception to next level ...")
      Console.WriteLine("-------------------------------------------------")
      Console.WriteLine()
      Throw e
   End Try
End Sub 'Level2Method


public void Level2Method()
{
   try 
   {
      ClassLevel3 nestedClass = new ClassLevel3();
      nestedClass.Level3Method();

   }
   catch (Exception e) 
   {
      Console.WriteLine(" Level2Method exception handler");

      // Display the full call stack at this level.
      StackTrace st1 = 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.
      StackTrace st2 = new StackTrace(new StackFrame(1, true));
      Console.WriteLine(" Stack trace built with next level frame: {0}",
         st2.ToString());

      // Build a stack trace skipping the current frame, and
      // including all the other frames.
      StackTrace st3 = new StackTrace(1, true);
      Console.WriteLine(" Stack trace built from the next level up: {0}",
         st3.ToString());

      Console.WriteLine();
      Console.WriteLine("   ... throwing exception to next level ...");
      Console.WriteLine("-------------------------------------------------\n");
      throw e;
   }
}

Visual C++


      void Level2Method()
      {
         try
         {
            ClassLevel3^ nestedClass = gcnew ClassLevel3;
            nestedClass->Level3Method();
         }
         catch ( Exception^ e ) 
         {
            Console::WriteLine( " Level2Method exception handler" );

            // Display the full call stack at this level.
            StackTrace^ st1 = gcnew 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.
            StackTrace^ st2 = gcnew StackTrace( gcnew StackFrame( 1,true ) );
            Console::WriteLine( " Stack trace built with next level frame: {0}", st2->ToString() );

            // Build a stack trace skipping the current frame, and
            // including all the other frames.
            StackTrace^ st3 = gcnew StackTrace( 1,true );
            Console::WriteLine( " Stack trace built from the next level up: {0}", st3->ToString() );
            Console::WriteLine();
            Console::WriteLine( "   ... throwing exception to next level ..." );
            Console::WriteLine( "-------------------------------------------------\n" );
            throw e;
         }

      }
