Throwing exceptions

Question

User893574298 posted

Some Syntax questions here;

try
{
   If(condition){
   }
   else{throw new Exception("bla bla" ) 
   }  
   If(condition){
   }
   else{throw new Exception("bla bla n2" ) 
   }  
}
 catch (Exception Excpt)
{
// LOG Excpt
}

 

would this be correct in terms of throwing exceptions :P

simply

try

{

   //Your if conditions here

}

Catch (Exeption ex)

{

   // catch ur exeption here

}

throwing exception in every if condition make more complications in large enterprise applications. Simple try..catch is simply enough if there is no unconditional behaviour to catch. Other advantage you can keep the consistency in your application.

hi thanks for replying

im adding error logging to a project so its not a case of beinging and to do better practices.. im an intern and havent really done error logging that much hence the syntax question..

in the (cs) pages im adding this logging, ive been told to keep the database logging count down hence throwing the error up for it to be captured.

so syntacticly would the syntax of below be correct ?

pageLoad function
{
try{
funtion1();
}
 catch (Exception Excpt)
{
// Log Excpt 
//display Excpt message.
}

funtion1
try
{
 if(condition)
 { 
   if(condition) 
   { }
   else{throw new exception ("error 2");}
  }
 else{throw new exception ("error 1");}
}
catch (Exception Excpt)
{
throw new Exception("funtion1()" +  Excpt.message);
}

It is wise to put your exception handling class to use on catch section. Create exeption handling class and send the loggedusername, error desription, datetime, and code method to the database.

We dont display any errors to the user on screen should one happen, we have a message displaying a code the code represents the error but only we hold the codes the idea being to not show anything to the users we log all errors to identify probelms quicker and log events for future reports.

anyways done now thanks.

using System;
public class EHClass 
{
   public static void Main () 
   {
      try 
      {
         Console.WriteLine("Executing the try statement.");
         throw new NullReferenceException();
      }

      catch(NullReferenceException e) 
      {
         Console.WriteLine("{0} Caught exception #1.", e); 
      }

      catch 
      {
         Console.WriteLine("Caught exception #2.");
      }

      finally 
      {
