关于global.asax.cs
做网站的时候,global.asax.cs要一直循环运行不停止,程序里面定义了一些数据结构,并且会用网络通信接受一些数据保存在这些结构里面,当有网页访问请求的时候,想调用这些数据,在这些页面对应的cs文件里应该怎样写代码去调用global.asax.cs文件里面的数据呢? --------------------编程问答-------------------- DEMOusing System;

得到一个数据库对象 --------------------编程问答-------------------- Application变量 --------------------编程问答--------------------
没太懂啊,意思是用数据库?刚试了下定义了个静态的全局变量,貌似可以实现 --------------------编程问答--------------------
我试试看
补充:.NET技术 , ASP.NET
