如何从app_code中的类设置母版页中的属性？ 与asp.net C＃

Question

How do I set a property in a master page from a class in app_code? with asp.net c#

my master page:

  private int styleGroup;
  public int StyleGroup
{
    get { return styleGroup; }
    set { styleGroup = value; }
}

how to I set StyleGroup from a class in the app_code? something like this, but it doesn't work:

Page currentPage = (Page)HttpContext.Current.Handler;
currentPage.Master.StyleID = 5;

thanks

Answer 1

You have to cast the MasterPage of current to you MasterPage Class, something like this

Page currentPage = (Page)HttpContext.Current.Handler;
((YourMasterPageClass)currentPage.Master).StyleID = 5;

Answer 2

将Page指针传递给app_code类函数，或在app_code中的类中设置Page成员。
