Also, Conditional compilation # If # else # endif & conditional attribute

When I was a beginner in. net, I usually write Conditional compilation like this:

 

 Code 

     ///     <Summary>  
  ///  Not recommended Conditional compilation methods
  ///     </Summary>  
   Public     Void  Checkdata (  Object  O)
{
#  If  Debug
  //  Do some  
  # Endif  
} 

 

In fact, the. NET Framework provides a good method for Conditional compilation. It is recommended to write:

 

Code 

     ///     <Summary>  
  ///  Define Conditional compilation for a method. recommended method
  ///     </Summary>  
  [Conditional ( "  Debug  "  )]
  Public     Void  Checkdata ()
{
  //  Todo check  
  } 

 

If it is a conditional compilation at the method level, our writing method will return:

 

 Code 

      Public     Void  Checkdata  <  T  >  (List  <  T  >  List)
{
  Try 
{
  //  Do something  
  }
  Catch  (Exception ex)
{
Logger. infoformat (ex. Message );
#  If  Debug
  Throw     New  Abnormaldataexception (string. Format (  "  New record exception {0} "  , Ex. Message), Ex );
  # Else  
  Throw     New  Abnormaldataexception (  "  An error occurred while adding a record.  "  , Ex );
  # Endif  
}
} 

 

Note:

1. identifier debug # debug case sensitive

2. Use conditional to split the SIMPLE METHOD
