调用方法在母版页 [英] Call Method in Master Page

问题描述

我在我的asp.net母版页的公共方法。是否有可能从内容页面调用这个，如果是哪些步骤/语法？

I have a public method in my asp.net Master Page. Is it possible to call this from a content page and if so what are the steps/syntax?

推荐答案

从在页，就可以把主页面为特定类型（你自己的法师类型暴露所需的功能），使用为来一边踩任何异常的类型不匹配：

From within the Page you can cast the Master page to a specific type (the type of your own Master that exposes the desired functionality), using as to side step any exceptions on type mismatches:

var master = Master as MyMasterPage;
if (master != null)
{
    master.Method();
}

在上面的code，如果主的类型是不是 MyMasterPage 然后主将空，没有方法的调用将尝试;否则会被称为预期。

In the above code, if Master is not of type MyMasterPage then master will be null and no method call will be attempted; otherwise it will be called as expected.
