Examples

The following example demonstrates the use of the ToString method. This code example is part of a larger example provided for the StackFrame class.

void InternalMethod()
{
   try
   {
      ClassLevel2^ nestedClass = gcnew ClassLevel2;
      nestedClass->Level2Method();
   }
   catch ( Exception^ e ) 
   {
      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.
      StackTrace^ st = gcnew StackTrace( gcnew 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() );
      Console::WriteLine( " Line Number: {0}", st->GetFrame( 0 )->GetFileLineNumber().ToString() );
      Console::WriteLine();
      Console::WriteLine( "   ... throwing exception to next level ..." );
      Console::WriteLine( "-------------------------------------------------\n" );
      throw e;
   }

}

public void InternalMethod()
{
   try
   {
      ClassLevel2 nestedClass = new ClassLevel2();
      nestedClass.Level2Method();
   }
   catch (Exception e)
   {
      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.
      StackTrace st = 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());

      Console.WriteLine(" Line Number: {0}",
         st.GetFrame(0).GetFileLineNumber().ToString());

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

      ' 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())
      
      Console.WriteLine(" Line Number: {0}", _
         st.GetFrame(0).GetFileLineNumber().ToString())
      
      Console.WriteLine()
      Console.WriteLine("   ... throwing exception to next level ...")
      Console.WriteLine("-------------------------------------------------")
