Question

Below code throw an exception at "Item.Update();"

    private void AddEmail()
    {
        site = SPContext.Current.Site;
        web = site.RootWeb;

        SPSecurity.RunWithElevatedPrivileges(delegate()
        {
            using (site = SPContext.Current.Site)
            {
                using (web = site.RootWeb)
                {
                    try
                    {
                        SPList list = web.Lists["Newsletter"];
                        SPListItem Item = list.Items.Add();
                        web.AllowUnsafeUpdates = true;
                        Item["Title"] = txtEmail.Text;
                        Item.Update();
                        SendEmail();

                        txtEmail.Text = "";
                    }
                    catch (Exception ex)
                    {
                        ltrMessage.Text = ex.Message;
                    }
                }
            }
        });
    }

Can anyone help me get over this ?

When running inside RunWithElevatedPrivileges, do not use SPContext.Current. Instead create a new SPSite object, passing in SPContext.Current.Site.Url.
