🚀 go-pugleaf

Hi Jon,
Actually it doesn't work, you have to pre declare your objects outside of
the try catch.
and then create inside the try catch, unlike delphi everything you want to
catch actually has to be in the block.


This code will fail because it wont be able to find the mywriter.close()
  try     { StreamWriter mywriter new StreamWriter("pathtofile"); }
   catch   {}
   finally { mywriter.Close(); }

this code will work, but wont catch the exception
StreamWriter mywriter new StreamWriter("pathtofile");
   try     {}
   catch   {}
   finally { mywriter.Close(); }

but this one will work and catch the exception
StreamWriter mywriter;
  try     { mywriter new StreamWriter("pathtofile"); }
   catch   {}
  finally { mywriter.Close(); }

I have verified this behavior on win32 and mono by putting a invalid path in
the stream writer, an if it's not done like the last example it won't catch
the exception.
