您将需要一个类型数组而不是字符串：

const types: ReadonlyArray<Type> = new Array(Comp1Class, Comp2Class);

<ng-container *ngFor="let componentTypeExpression of types">
  <ng-container *ngComponentOutlet="componentTypeExpression"></ng-container>
</ng-container>

请记住，它们都必须位于注射器的entryComponents中。对于惰性模块，您可以添加注入器，甚至可以定制模块工厂： https://angular.io/api/common/NgComponentOutlet

Angular/typescript load component from variable
