如何在typescript中通过类型安全增强“this”

class MyClass {
  private value: number = 10;

  public myMethod = (): void => {
    console.log(this.value);
  }
}

const instance = new MyClass();
instance.myMethod(); // 输出：10

class MyClass {
  private value: number = 10;

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

const instance = new MyClass();
const boundMethod = instance.myMethod.bind(instance);
boundMethod(); // 输出：10

function BindThis(target: any, propertyKey: string, descriptor: PropertyDescriptor): PropertyDescriptor {
  const originalMethod = descriptor.value;
  descriptor.value = function(...args: any[]): any {
    return originalMethod.apply(this, args);
  };
  return descriptor;
}

class MyClass {
  private value: number = 10;

  @BindThis
  public myMethod(): void {
    console.log(this.value);
  }
}

const instance = new MyClass();
instance.myMethod(); // 输出：10
