Page的 Context属性跟HttpContext.Current引用相等的
这是用reflector查看到的代码。

protected  internal  override  HttpContext Context
{
    [TargetedPatchingOptOut( "Performance critical to inline across NGen image boundaries" )]
    get
    {
        if  ( this ._context ==  null )
        {
            this ._context = HttpContext.Current;
        }
        return  this ._context;
    }
}

public  virtual  HttpSessionState Session
{
    get
    {
        if  (! this ._sessionRetrieved)
        {
            this ._sessionRetrieved =  true ;
            try
            {
                this ._session =  this .Context.Session;
            }
            catch
            {
            }
        }
        if  ( this ._session ==  null )
        {
            throw  new  HttpException(SR.GetString( "Session_not_enabled" ));
        }
        return  this ._session;
    }
}
