Exception while opening epub file in C#

Question

I am trying to read epub book using C#.NET but I am getting the following excetion: Object reference not set to instance of an object.

I am trying epub for the first time and this is where I have referred.

Code:

static void Main(string[] args)
        {
            try
            {
                Epub book = new Epub(@"d:\test.epub"); //this is the line where i am getting error
                String Title = book.Title[0];
                String Author = book.Creator[0];

                Console.WriteLine("Name:" + Title);
                Console.WriteLine("Author:" + Author);

            }
            catch (Exception e)
            {
                Console.WriteLine("Exception: " + e.Message);
            }
            Console.ReadKey();
        }

Any ideas?? Thanks!!

I've tried to run your code locally and it worked on my machine. And it works for other epub files, as you've said in comment.
Also I've taken a brief look into Epub's code-base and didn't find anything that could obviously cause the error, plus NullReferenceException means that:

1. Your epub file is broken or corrupted
2. Your epub file does not have some specific piece of (meta)data that Epub lib expects.

In both cases I'd recommend you to try to re-create/re-convert that not working d:\test.epub file or abandon it :)
