C# 6.0–Exception Filters

This blog post is part of C# 6.0 Features Series.

C# 6.0 contains lots of small features and one of them is Exception filters. It is already there with VB.NET earlier but now it is available in C# also. In exception filters now if exception is combined with Exception statement and If condition of if satisfy then it will execute that block.

Let’s take a simple example to understand it better. Following is a code for a simple console application. Before exception filters we were able to write a code like following.

using System;

namespace ExceptionFilters
{
    class Program
    {
        static void Main(string[] args)
        {
            try
            {
                throw new Exception("Jalpesh");
            }

            catch (Exception ex)
            {
                if(ex.Message =="Jalpesh")
                    Console.WriteLine("Exception with Message Jalpesh is executed");
                else
                    Console.WriteLine("Exception with Message DotNetJalps executed");
            }
        }
    }
}

In above example, I have thrown a exception in try block and in catch block I have written if-else block to check message and based on that it will print some method.
