你的代码逻辑不清楚，大致应该改成这样        Users user = null;        if (Session["currentUser"] == null)
            return;        user = Session["currentUser"] as Users;
        if (user == null)
            return;        this.lblUser.Text = "";
        this.imgbtnComplaint.Enabled = true;
        this.imgbtnLink.Enabled = true;        string userId = "xikemen" + user.UserId.ToString();
        HttpCookie cookieNew = new HttpCookie(userId);
        string ids = Request.QueryString["id"] + ",";        if (Request.Cookies[userId] == null)
        {
            cookieNew.Values.Add("Clicked", "");
        }
        else
        {
            if (cookieNew["looked"] != null)
            {
                if (!cookieNew["looked"].Contains(Request.QueryString["id"]))
                {
                    ids += Request.QueryString["id"] + ",";
                }
            }
        }
        cookieNew.Values.Add("looked", ids);
        cookieNew.Expires = DateTime.Now.AddDays(30);
        Response.Cookies.Add(cookieNew);
