Answer 4

在程序里添加一个timer控件，然后在该控件的属性的Interval设置每隔多长时间执行一次，这里的单位是毫秒，然后双击timer控件，在里面写代码：检测有没有服务B和C的进程，有的话就什么都不执行，没有的话就用Process.Start（"服务名"）启动起来。关于进程的操作，可以参考下列文章：http://blog.csai.cn/user1/22158/archives/2007/16631.html

Answer 5

建议不要这样做。1、服务作为长时间运行的程序，本身应该是健壮的。用守护进程的方式来解决服务不稳定，只会带来新的问题。2、对于关键服务，Windows已经提供了恢复功能，允许在服务出错的情况下重启服务，甚至重启系统。
