示例

以下示例将两个键值对添加到与用户控件关联的应用程序状态（如果用户控件 IsPostBack 的属性返回 false）。 满足此条件后，代码会通过用户控件Application的属性使用Add该方法添加键及其值。

if (!myControl.IsPostBack)
{
  // Add new objects to the HttpApplicationState.
  // These will be maintained as long as the application is active.
  myControl.Application.Add("Author","Shafeeque");
  myControl.Application.Add("Date",new DateTime(2001,6,21));
  // Add an object to the cache with expirations 
  // set to 0.1 minute.
  myControl.Cache.Insert("MyData1", "somevalue", null, DateTime.Now.AddMinutes(0.1), Cache.NoSlidingExpiration);
}

If (Not myControl.IsPostBack) Then
  ' Add new objects to the HttpApplicationState.
  ' These will be maintained as long as the as the application is active.
  myControl.Application.Add("Author","Shafeeque")                
  myControl.Application.Add("Date",new DateTime(2001,6,21))
  ' Add an object to the cache with expirations
  ' set to 0.1 minute.
  myControl.Cache.Insert("MyData1", "somevalue", Nothing, DateTime.Now.AddMinutes(0.1), Cache.NoSlidingExpiration)
