Why in Log Default Error

[agafon2]

Hello

I use this code to write:

                using (FileStream stream = new FileStream(Files_way+Prefix+Symbol+i_period, FileMode.Append, FileAccess.Write, FileShare.ReadWrite)){                    
                  using (BinaryWriter writer = new BinaryWriter(stream)){
                    //Print("Print");
                    i_time=Convert.ToInt32(Time[0].Subtract(new DateTime(1970,1,1)).TotalSeconds);
                    //Print(i_time);
                    writer.Write(Convert.ToInt32(i_time));
                    writer.Write(Bulls_Volume);    
                    writer.Write(Bulls_Tick);
                    writer.Write(Bears_Volume);
                    writer.Write(Bears_Tick);
                    //writer.Write(Volume[0]);
                      
                    //writer.Flush();
                    writer.Close();                            
                  }
                }

but there is Default error in log

Sorry agafon2, would unfortunately not have an idea from the code presented - are you sure this is tied to running this very script? I would suggest standard C# try / catch to further isolate out where it occurs then.
