htmlencode

I have many params making up an insert form for example:

x.Parameters.AddWithValue("@city", City.Text)

I had a failed xss attack on the site this morning, so I am trying to beef up security measures anyway....

Should I be adding my input params like this?

x.Parameters.AddWithValue("@city", HttpUtility.HtmlEncode(City.Text))

Is there anything else I should consider to avoid attacks?

Thanks
