推荐答案

首先，静态"和对象"确实没有什么意义.
任何静态类都不能实例化.因此，您不能创建普通类的静态实例对象.

如果您将类定义为静态
例如

First of all ''static'' and ''object'' really makes little sense.
Any static class cannot be instantiated. So you cannot create a static instance object of a normal class.

If you define your class as static
e.g.

static class ReceiveMsgService()

您将可以直接访问其他类中的静态成员.

否则，您唯一的选择是创建一个实例-
ReceiveMsgService o = new ReceiveMsgService();，然后相应地使用它.

you will be able to direcly access static members inside the other class.

Otherwise the only option you have is to create an instance -
ReceiveMsgService o = new ReceiveMsgService(); and then use it accordingly.

静态ReceiveMsgService对象= new ReceiveMsgService();

一切正常.

static ReceiveMsgService object = new ReceiveMsgService();

and it is working fine.
