When would you use the attribute ChildActionOnly? What is a ChildAction and in what circumstance would you want restrict an action using this attribute?
推荐答案
ChildActionOnly 属性确保动作方法只能作为子方法调用从视图中.一个动作方法不需要有这个属性作为子动作使用，但是我们倾向于使用此属性来防止操作方法因用户而被调用要求.定义了一个动作方法后，我们需要创建动作时将呈现的内容调用.子操作通常与部分视图相关联，尽管这不是强制性的.
The ChildActionOnly attribute ensures that an action method can be called only as a child methodfrom within a view. An action method doesn’t need to have this attribute to be used as a child action, butwe tend to use this attribute to prevent the action methods from being invoked as a result of a userrequest.Having defined an action method, we need to create what will be rendered when the action isinvoked. Child actions are typically associated with partial views, although this is not compulsory.
