大家好，

知道如何在下面的应用程序中连续运行吗?

感谢您对此的反馈.
谢谢!!!

推荐答案

将其转换为Windows服务.

Turn it into a windows service.

正如约翰·西蒙斯(John Simmons)所说的那样，这是最好的选择.如果您不想创建Windows服务，则可以使用以下代码，但不建议使用.

方法末尾的

As John Simmons said that is the best option. If you dont want to create a windows service then you can use the below code, but not recommended.

while (true)
{
       TimerCallback callback = Program.CounterApp;
       Timer stateTimer = new Timer(callback, null, 0, 1000);
}

使用递归再次调用它.
