Try to catch the use of specific exceptions and avoid using system. Exception

2. Exception handling areas to be aware of1) Catch and finally code should be very short, and the success rate is very high, to avoid throwing an exception. Otherwise the CLR terminates the process, avoiding security breaches or unpredictable consequences. This is similar to Windows blue screen, a serious error has occurred, preferring to make the system unusable. 2) Catch block try to avoid directly catching the base class exception of the exception, but should catch the specific exception class.
