打開/關閉MdDialog裏面的angular2服務

Question

我有服務和錯誤處理服務，當我試圖調用對話框代碼，它會給出錯誤。

import { MdDialog, MdDialogRef } from '@angular/material'; 
import { HeaderDialog } from '../dialog-boxes.component'; 

export class MyService { 
dialogRef: MdDialogRef<any>; 
constructor(private dialog: MdDialog) {} 
this.dialogRef = this.dialog.open(HeaderDialog, { 
    height: 'auto', 
    width: 'auto', 
}); 

this.dialogRef.componentInstance.message = 'Hello'; 
this.dialogRef.afterClosed().subscribe(result => { 
    if (result) {} 
    this.dialogRef = null; 
}); 
} 

Unhandled Promise rejection: Error: Invalid providers for "HeaderDialog" - only instances of Provider and Type are allowed, got: [EConfig, Constants, ?undefined?, ...]

你應該張貼您的組件HeaderDialog，在此組件你有問題。
