我正在开发一个以Angular 17编辑用户数据的简单对话框.问题是，当我try 从父组件注入数据时，VSCode中显示一个错误，内容如下:
没有合适的注入令牌用于UsersCrudmodalComponent类的参数‘Data’.考虑使用@Inject修饰符来指定注入令牌.
这是现在的代码:
家长:
editUser(uuid: string) {
const user: IUser | undefined = this._users.find((f: IUser) => (f.uuid = uuid));
const dialogRef = this.dialog.open(UsersCrudModalComponent, { data: { user: user } });
}
对话:
constructor(
private readonly _dialogRef: MatDialogRef<LoginModalComponent>,
private readonly _usersService: UsersService,
private readonly _translate: TranslateService,
@Inject(MAT_DIALOG_DATA) public data: { user: IUser },
) {
this.user = this.data.user;
}
另一方面，如果我将@Inject行移动到构造函数注入的第一行，我会得到这个错误:
作为表达式调用时，无法解析参数修饰符的签名."0"类型的参数不能赋值给"3"类型的参数.
我怀疑这与打字本有关，但我看不出有什么奇怪的地方.

I modified the Tsconfig.json, changing experimentalDecorators from true to false. Now the first error doesn't appear anymore, but I still have the "没有合适的注入令牌用于UsersCrudmodalComponent类的参数‘Data’.考虑使用@Inject修饰符来指定注入令牌."
