Chrispy的评论正确."...您可以将#templateRef添加到包含该元素的已嵌入组件(即不在ng-content上)，然后可以将其用作选择器."

Chrispy's comment is correct. "...you can add the #templateRef to the transcluded component where it is being included (i.e. not on the ng-content), then you can use that as the selector instead."

所以我有我的父(模态)组件:

So I have in my parent (modal) component:

@ContentChild('transcludedContent') private transcludedContent: ModalContent;

然后将模态输入到哪里:

Then where the modal is brought in I have:

<modal>
  <transcluded-component #transcludedContent>
  </transcluded-component>
</modal>
