如何从被调用组件内部访问MatDialogConfig?

您可以使用 componentInstance 属于 MatDialogRef<T> 。只需获取对话框的引用即可获取 MatDialogRef :

打开对话框的方法:

openDialog(dialogConfig: MatDialogConfig) {
  let dialogRef = this.dialog.open(MyDialogComponent);
  // You can rename the dialogConfig instance to whatever you want. See the next code snippet for more info.
  dialogRef.componentInstance.dialogConfig = dialogConfig;
}

对话框组件:

export class MyDialogComponent implements OnInit {
  // Rename the property to whatever you want it to be
  dialogConfig: MatDialogConfig;
  ngOnInit() {
    console.dir(`Dialog config: ${this.dialogConfig}`);
  }
}
