很多时候,我们希望服务程序可以直接运行,或者可以响应一些参数,这时候,混合Windows服务和Windows窗体的程序就排上用场了。要实现同时支持Windows服务和Windows窗体,需要在启动的第一步时判断当前运行环境是否为服务模式,可以从以下几个方面进行判断:
- 会话ID:Process.SessionId,获取当前进程的SessionId,为0则可以是服务模式(谢谢1楼提醒);
- 当前用户名称:Environment.UserName,如果为SYSTEM则可以是服务模式
- 是否用户交互模式:Environment.UserInteractive,为false时也可以认为是服务模式
- 自定义启动参数:创建服务时添加一个特定的启动参数,比如[/s],然后代码中检查启动参数args[0] == "/s"
如果上述条件都不成立,就进入窗体模式,或者是响应一些其他的命令行参数,比如安装服务[/i]、卸载服务[/u]等。
项目需要添加下面的组件引用:
- System.Configuration.Install
- System.ServiceModel
- System.ServiceProcess
项目包含的类文件:
- Program.cs:根据运行模式执行服务或者窗体,或者响应命令行参数;
- MainService.cs:服务类,实现与窗体类一致的功能;
- MainForm.cs:窗体类,实现与服务类一致的功能,还可以添加一些安装和卸载服务,启动和停止服务的管理功能;
- MainWorker.cs:实现功能的类,服务类与窗体类都调用该类;
- ServiceInstaller.cs:服务安装类,可以调用框架的InstallUtil.exe工具安装卸载服务。
各个类的代码如下:
