推荐答案

您可以从基类继承页面.然后，您可以在基类中创建一个虚拟方法，该方法将在您的页面中被覆盖.然后，您可以像这样从主页上调用该虚拟方法-

You can inherit your page from a base class. Then you can create a virtual method in your base class which will get overridden in your page. You can then call that virtual method from the master page like this -

(cphPage.Page as PageBase).YourMethod();

在这里， cphPage 是母版页中 ContentPlaceHolder 的ID. PageBase 是包含 YourMethod 方法的基类.

Here, cphPage is the ID of the ContentPlaceHolder in your master page. PageBase is the base class containing the YourMethod method.

当然，在使用页面实例调用 YourMethod 方法之前，您必须进行空检查.

Of course, you'll have to put a null checking before you call the YourMethod method using the page's instance.
