我加上异步执行以后总是提示我：只有在配置文件或 Page 指令中将 enableSessionState 设置为 true 时，才能使用会话状态。还请确保在应用程序配置的 <configuration>\<system.web>\<httpModules> 节中包括 System.Web.SessionStateMod 或自定义会话状态模块。
但是如果我用如下方式，就不会报错：
public void AddLog(string logMsg, DateTime? opertionTime, DateTime? responseTime)--------------------编程问答-------------------- 你有没有实际测试出来、此时搞asp.net异步页面有什么意义呢？ --------------------编程问答-------------------- 页面的cs里不行，就新建类库，里去记日志！ --------------------编程问答--------------------

LogHelperController log = new LogHelperController();
log.AddLog(userID, userName, bussinessName, opertionTimes, responseTimes, recordTime, com_Code, client_IP, logMsg);
}
}
catch { }
}
我就是建的类库啊，记日志的方法放到类库里面，然后在页面中调用类库中的方法。。
补充：.NET技术 , ASP.NET
