注解
DefaultProperty仅当字符串传递到构造函数时,才会使用属性 ParseChildrenAttribute 。The DefaultProperty property is used only if a string is passed to the ParseChildrenAttribute constructor. ParseChildrenAttribute创建类时, DefaultProperty 属性将定义正在分析的服务器控件的默认属性。When the ParseChildrenAttribute class is created, the DefaultProperty property defines the default property for the server control that is being parsed.
