Application对象
Applocation对象用于共享应用程序级信息,即多个用户可以共享一个Applocation对象。
用户在请求Asp.Net文件时,将启动应用程序并且创建Application对象。一旦Application对象被创建,就可以共享和管理整个应用程序的信息。在应用程序关闭之前,Application对象一直存在,所以Application对象是用于启动和管理ASP.NET应用程序的主要对象。
Application对象常用集合
集合名 | |
Contents | 用于访问应用程序状态集合中的对象名 |
StaticObjects | 确定某对象指定属性的值或遍历集合,并且检索所有静态对象的属性 |
Application对象常用属性
属性 | |
AllKeys | 返回全部Application对象变量名到一个字符串数组中 |
Count | 获取Application对象的数量 |
Item | 允许使用索引或Application变量名称传回内容值 |
Application对象常用方法
方法 | |
Add | 新增一个Application对象变量 |
Clear | 清除全部Application对象变量 |
Lock | 锁定全部Application对象变量 |
Remove | 使用变量名移除一个Application对象变量 |
RemoveAll | 移除全部Application对象变量 |
Set | 使用变量名称更新一个Application对象变量的内容 |
UnLock | 解除锁定的Application对象变量 |
1.用Application实验一个访问计数器
主要用来记录应用程序曾经被访问的次数的组件。主要通过Application对象和session对象来实现,我们在昨天的项目添加一个Global.asax文件,具体代码如下:
