我试图按照https://material.angular.io/components/component/dialog上的文档但我不明白为什么它有以下问题？

我在我的组件上添加了以下内容:

@Component({
  selector: 'dialog-result-example-dialog',
  templateUrl: './dialog-result-example-dialog.html',
})
export class DialogResultExampleDialog {
  constructor(public dialogRef: MdDialogRef<DialogResultExampleDialog>) {}
}

在我的模块中,我补充道

import { HomeComponent,DialogResultExampleDialog } from './home/home.component';

@NgModule({
  declarations: [
    AppComponent,
    LoginComponent,
    DashboardComponent,
    HomeComponent,
    DialogResultExampleDialog
  ],

// ...

但我得到这个错误....

EXCEPTION: Error in ./HomeComponent class HomeComponent - inline template:53:0 caused by: No component factory found for DialogResultExampleDialog. Did you add it to @NgModule.entryComponents?
