help with returning an array...

Ok, i have the following code, but im having trouble returning the array of BlogEntry objects....

Code:

---

            BlogEntry[] _blogEntries = new BlogEntry[_totalEntries];

            for (int i = 0; i <= _totalEntries; i++) {

                BlogEntry _entry = new BlogEntry();
                _entry.Id = (int)dsBlogPosts.Tables[0].Rows[i]["entry_id"];
                _entry.Title = (string)dsBlogPosts.Tables[0].Rows[i]["entry_title"];
                _entry.Post = (string)dsBlogPosts.Tables[0].Rows[i]["entry_post"];
                _entry.PostDescription = (string)dsBlogPosts.Tables[0].Rows[i]["entry_post_desc"];
                _entry.PostDate = (DateTime)dsBlogPosts.Tables[0].Rows[i]["entry_post_date"];
                _entry.Ip = (string)dsBlogPosts.Tables[0].Rows[i]["entry_ip"];
                _entry.CategoryName = (string)dsBlogPosts.Tables[0].Rows[i]["category_name"];
                _entry.Author = (string)dsBlogPosts.Tables[0].Rows[i]["author_name"];
                _entry.AuthorEmail = (string)dsBlogPosts.Tables[0].Rows[i]["author_email"];
                _blogEntries[i] = _entry;

            }
            return _blogEntries;

i get an error on the 'return _blogEntries;' line. cannot convert type BlogEntry[] to BlogEntry is the error message...

if i do a 'return _blogEntries[];' i get a Expecting value...but a 'return _blogEntries[0];' works fine...will this return the first dimension of the array...or the first key...

whats the correct return syntax??

Thanks, Justin

You've declared your method as returning a BlogEntry rather than a BlogEntry[], i.e. an array of BlogEntry objects. That's what the error message is telling you. The method returns a BlogEntry and you're specifying a BlogEntry[] in the return statement. It cannot convert one to the other so it falls over.

ahh, see now that makes sense. how ever i didnt realise an object, and an array of that object were different objects.

OOP mimics the real world. Are an egg and an egg carton different things? Yes they are: one is a container that can hold multiple instances of the other. So are a BlogEntry and a BlogEntry[].
