How to: Use Finally Blocks | Microsoft Docs[^]

What I have tried:

class Program
    {
        static void Main(string[] args)
        {

            new Program().Mehtod();
            Console.Read();
        }

        public void Mehtod()
        {
            int[] array1 = { 0, 0 };
            int[] array2 = { 0, 0 };

            try
            {
                Array.Copy(array1, array2, -1);
            }
            catch (ArgumentOutOfRangeException e)
            {
                Console.WriteLine("Error: {0}", e);
                throw;
            }
            finally
            {
                Console.WriteLine("This statement is always executed.");
            }
        }
    }

Yes it does always execute. A block like this actually gets compiled into something like the below:

C#

try
{
  try
  {
    ..
  }
  catch (..)
  {
    ..
  }
}
finally
{
  ..
}

If you run your code directly in Visual Studio you probably won't see the finally block because the console window will close almost immediately once the throw; line is called, not giving you enough time to see the printed message. However, if you actually run the application from a Command Prompt, you should see the exception printed out and then see the code in the finally block.
