Request.Params 用法简例

前台页面：

<a href='?add=<%# Eval("UserID") %> ' onclick="return Confi()" id="addhref"></a>

后台Page_Load方法中：

if (!string.IsNullOrEmpty(Request.Params["add"])) //添加好友
        {
            string ID = Convert.ToString(Request.Params["add"]);
            try
            {
                if (!sc.AddFriends(FoundationMethod.GetUserByCookieName("user"), ID))
                {
                    Response.Write("<script>alert('添加成功');</script>");
                }
                else
                {
                    Response.Write("<script>alert('添加失败');</script>");
                }
            }
            catch { Response.Write("<script>alert('添加失败');</script>"); }
        }
