我如何让我的组件读入一个Angular属性？

import { Component, Input } from '@angular/core';

@Component({
  selector: 'app-my-component',
  template: '<p>{{ myProperty }}</p>'
})
export class MyComponent {
  @Input() myProperty: string;
}

<app-my-component [myProperty]="parentProperty"></app-my-component>

import { Component } from '@angular/core';

@Component({
  selector: 'app-parent-component',
  template: '<app-my-component [myProperty]="parentProperty"></app-my-component>'
})
export class ParentComponent {
  parentProperty: string = 'Hello, World!';
}
