I know it sounds weird but I am required to put a wrapping try catch block to every method to catch all exceptions. We have thousands of methods and I need to do it in an automated way. What do you suggest?

I am planning to parse all cs files and detect methods and insert a try catch block with an application. Can you suggest me any parser that I can easily use? or anything that will help me...

every method has its unique number like 5006

public static LogEntry Authenticate(....)
        {
            LogEntry logEntry = null;
            try
            {
                ....
                return logEntry;
            }

            catch (CompanyException)
            {
                throw;
            }

            catch (Exception ex)
            {
                logEntry = new LogEntry(
                    "5006",
                    RC.GetString("5006"), EventLogEntryType.Error,
                    LogEntryCategory.Foo);

                throw new CompanyException(logEntry, ex);
            }
        }
