Sounds like there's a problem with your code, but you didn't include your
code, or any details about what you are doing beyond using SubString() so I
really don't see how anyone can help you.

Perhaps you should show, or at least describe, just what you are doing.

Beyond that, you can set a break point at look at the string being passed to
Substring and your arguments and you should be able to see why it returns
what it does.

Goo evening,

I think he's trying to trim text containing HTML content (which isn't
trivial).

Perhaps, that's something I've done. It's just hard to help someone when
they don't show what they did.

Remove tag by means of a regular expression.

Regex re = new Regex("<[^>]*>", RegexOptions.Multiline);
string pureText = re.Replace(originalString, "");

And then pureText.SubString(..

Goo evening guys,

Having said it's not a trivial task i meant it's not trivial when trimming
text but persisting HTML. Mars' resolution will work only in most all of the
cases, but not if you trim the text at a html encoded character. This case is
easy to handle by making sure by checking if the ampersand is not included in
last 6 characters. Similar issue to this:
