Question

What could be the problem?
I get this message:
An object reference is required to access non-static member labb3.linkClass.getLinks()

    namespace labb3
{
    public partial class visalinks : System.Web.UI.Page
    {
        protected void Page_Load (object sender, EventArgs e)
        {
            userClass newUser = (userClass)Session["userClass"];
            ArrayList Poster = linkClass.getLinks();

            foreach (object o in Poster) {
                linkClass lnks = (linkClass)o;
                Response.Write(lnks.webbadress);
            }
        }
    }
}

Answer 1

linklClass is name of your class, and getLinks is a method in this class – but getLinks isn’t static, so in order to use it – you have to create instance of the class:

linkClass inst = new linkClass();
inst.getLinks()

or… just make getLinks static, if it’s possible.
