ViewContainerRef类具有用于访问子级的length和get(index)属性.在此处查看API:

The ViewContainerRef class has length and get(index) properties for accessing children. See the API here:

https://angular.io/docs/ts/latest/api/core/index/ViewContainerRef-class.html

因此，要引用特定的子代，请使用viewContainerRef.get(childOfInterestIndex)，并使用诸如for(var index = 0; index < viewContenrRef.length; index++)

So to reference a specific child, you use viewContainerRef.get(childOfInterestIndex), and to work on all children you use a for loop, using something like for(var index = 0; index < viewContenrRef.length; index++)
