Ajax里面用Session

如果在Ajax里面直接写上Session["aa"]是取不到值的.

必须的用[AjaxPro.AjaxMethod(AjaxPro.HttpSessionStateRequirement.ReadWrite)]

来进行声明AJAX方法.里面还要用HttpContext.Current.Session["playList"]进行都必须明是当前页用的Session.

正确的例子如下:

[AjaxPro.AjaxMethod(AjaxPro.HttpSessionStateRequirement.ReadWrite)]//声明
  public void PlayList(int[] List)
  {
   HttpContext.Current.Session["playList"] = List;//用HttpContext.Current;

  }
