C# .net framework不使用命令行或第三方库实现服务安装、卸载、停用,启用

网上资料通常都通过命令行调用sc.exe进行,这里介绍一种通过微软提供API实现的方法。代码更加简单,可控性更好。

使用方法

static void Main(string[] args)
{
    if (args.Length == 0) {
        // Run your service normally.
        ServiceBase[] ServicesToRun = new ServiceBase[] {new YourService()};
        ServiceBase.Run(ServicesToRun);
    } else if (args.Length == 1) {
        switch (args[0]) {
            case "-install":
                InstallService();
                StartService();
                break;
            case "-uninstall":
                StopService();
                UninstallService();
                break;
            default:
                throw new NotImplementedException();
        }
    }
}

ServiceControl 类

 public class ServiceControl
    {
        const string ServiceName = "MyService";

        public static bool IsInstalled()
        {
            using (ServiceController controller =
                new ServiceController(ServiceName))
            {
                try
                {
                    ServiceControllerStatus status = controller.Status;
                }
                catch
                {
                    return false;
                }
                return true;
            }
        }

        public static bool IsRunning()
        {
            using (ServiceController controller =
                new ServiceController(ServiceName))
            {
                if (!IsInstalled()) return false;
                return (controller.Status == ServiceControllerStatus.Running);
            }
        }

        public static AssemblyInstaller GetInstaller()
        {
            AssemblyInstaller installer = new AssemblyInstaller(
                typeof(MyService).Assembly, null);
            installer.UseNewContext = true;
            return installer;
        }

        public static void InstallService()
        {
            if (IsInstalled()) return;

            try
            {
                using (AssemblyInstaller installer = GetInstaller())
                {
                    IDictionary state = new Hashtable();
                    try
                    {
                        installer.Install(state);
                        installer.Commit(state);
                    }
                    catch
                    {
                        try
                        {
                            installer.Rollback(state);
                        }
                        catch { }
                        throw;
                    }
                }
            }
            catch
            {
                throw;
            }
        }

        public static void UninstallService()
        {
            if (!IsInstalled()) return;
            try
            {

                    try
                    {
                        installer.Uninstall(state);
                    }
                    catch

            using (ServiceController controller =

建立了一个独立项目交流群

建立了一个"独立项目交流群",本群主要交流开源项目的运作模式和盈利模式。

大家可以在名字前面加地区,以及熟悉的技能,如“长沙-全栈-ning”,名字建议用昵称。

目前还没有项目启动,大家可以想一想,可以先分享一些开源或者商业案例,慢慢形成讨论氛围。

注意:

  • 群永久免费
  • 卖课永久严禁加入
  • HR暂时严禁加入
  • 以前叫做开源项目交流群,后来发现大家可能不一定选择开源,所以就改一下吧
