在Typescript中，如何访问“匿名”类外部的成员

let myClass = class {
  private myProperty: string = "Hello";

  public myMethod(): void {
    console.log(this.myProperty);
  }
};

let instance = new myClass();
instance.myMethod(); // 输出：Hello

function createInstance(): any {
  let myProperty: string = "Hello";

  return class {
    public myMethod(): void {
      console.log(myProperty);
    }
  };
}

let myClass = createInstance();
let instance = new myClass();
instance.myMethod(); // 输出：Hello
