获取Typescript中所有私有成员列表的方法？

npm install reflect-metadata

import "reflect-metadata";

class MyClass {
  private privateField: string;
  public publicField: number;

  constructor() {
    this.privateField = "private";
    this.publicField = 123;
  }
}

const keys = Reflect.getMetadataKeys(MyClass.prototype);
console.log(keys);

import "reflect-metadata";

class MyClass {
  private privateField: string;
  public publicField: number;

  constructor() {
    this.privateField = "private";
    this.publicField = 123;
  }
}

const keys = Reflect.getMetadataKeys(MyClass.prototype);
const privateKeys = keys.filter(key => key.startsWith("design:private"));
const privateValues = privateKeys.map(key => Reflect.getMetadata(key, MyClass.prototype));
console.log(privateValues);
