because this line is not good:

           foreach (DirectoryInfo diNext in dirs)
            {
                Console.WriteLine(diNext.GetFiles("*.doc"));
            }

diNext.GetFiles() will return an array of files that matches the expression.
How do you want .net to create a string that "represents" a reference to an
array?

The default way to do this is to print out the type, which is what you are
getting. If you want to print out the actual contents, then you will need
an inner loop to scan through the array, get the file names, and print them
out.
