Today I saw a discussion on FB questioning "Can multiple catch blocks be executed?". Many guys were confused in answering that question, few of them answered "YES".
Today I saw a
discussion on FB questioning "Can multiple catch blocks be executed?". Many
guys were confused in answering that question, few of them answered "YES". I am
writing this post to support my answer.
Here is a program in
support with this answer.
using System;
using System.Linq;
namespace ConsoleApplication1
{
//Run this program and type 0 (that is numeric) and
'a' (that is char) on the console to check both catch blocks in action.
class Program
{
static void
Main(string[] args)
{
try
{
int numerator = 10;
int denominator = GetText();
int result = numerator / denominator;
}
catch (DivideByZeroException
ex1)
{
string msg = ex1.Message.ToString();
Console.WriteLine(msg +
" I'm from 1st catch block");
}
catch (Exception
ex2)
{
string msg = ex2.Message.ToString();
Console.WriteLine(msg +
" I'm from 2nd catch block");
}
finally
{
//Console.WriteLine("In finally block.");
}
Console.ReadKey();
}
private static
int GetText()
{
string x =
Console.ReadLine();
return
Convert.ToInt32(x);
}
}
}
The output of this program is: "Attempted to divide by zero".
So, yes it is possible to execute multiple catch blocks,
just keep all catch blocks in order means put your super class exception (that
is "Exception ex2" in above code) at the bottom.
