1. 19. 1. Using finally

Sometimes you can define a block of code that will execute when a try/catch block is left.

The general form of a try/catch that includes finally is shown here:


      try {
        // block of code to monitor for errors
    }
    catch (ExcepType1 exOb) {
        // handler for ExcepType1 
    }
    catch (ExcepType2 exOb) {
        // handler for ExcepType2 
    }
    .
    .
    .
    finally {
        // finally code
    }

  

The finally block will be executed whenever execution leaves a try/catch block.

 
 
using System; 
 
class MainClass 
  public static void Main() { 
 
    Console.WriteLine("Receiving ")
    try 
      int i=1, j=0;
      
      i = i/j; 

    
    catch (DivideByZeroException) { 
      Console.WriteLine("Can't divide by Zero!")
      return
    
    catch (IndexOutOfRangeException) { 
      Console.WriteLine("No matching element found.")
    
    finally 
      Console.WriteLine("Leaving try.")
    
  }   
  
}

        
Receiving
Can't divide by Zero!
Leaving try.
