Typescript getter and setter error
提问by rtn
Ok it's my first day doing some Angular 2 using typescript and I am try to make a simple getter and setter service.
好的，这是我第一天使用 typescript 做一些 Angular 2，我正在尝试制作一个简单的 getter 和 setter 服务。
import {Injectable} from "angular2/core";
@Injectable()
export class TodoService {
private _todos:Array = [];
get todos():Array {
return this._todos;
}
set todos(value:Array) {
this._todos = value;
}
}
Can anyone explain why the Typescript compiler is throwing the following error as I think it should be ok.
任何人都可以解释为什么 Typescript 编译器会抛出以下错误，因为我认为应该没问题。
ERROR in [default] /Users/testguy/WebstormProjects/angular2-seed/src/app/services/todo-service.ts:6:17
Generic type 'Array<T>' requires 1 type argument(s).

You should really need to mention which kind of Arrayyou want while defining it, MyClasscan be string/number(datatype)
你真的需要Array在定义它时提到你想要哪种类型，MyClass可以是string/ number（数据类型）
Code
代码
export class TodoService {
private _todos:Array<MyClass> = [];
get todos():Array<MyClass> {
return this._todos;
}
set todos(value:Array<MyClass>) {
this._todos = value;
}
}
