制作本地服务监视主程序的运行

vs自带的有本地服务项目，创建即可。这些不多说了，好多博客都有，我只说几点注意的点：

1、

 

 选localsystem，选localservice不行，不知道为啥

2、对于我的功能是要监控主程序是否运行，没运行的，我需要把主程序启动，这个是比较麻烦的，因为服务是不能启动exe的，具体原因好像是本地服务和winform程序不在同一消息队列还是什么的具体忘了，后来也是查了半天找到的方法。

public class SoftStart
    {
        public static void Start(string commandLine, bool showWindow)
        {
            IntPtr hToken;
            IntPtr hTokenDup;
            const int TOKEN_ALL_ACCESS = 268435456;
            const int TokenSessionId = 12;
            const uint CREATE_PROCESS_FLAGS = 0x00000020 | 0x00000010 | 0x400;

            if (!OpenProcessToken(GetCurrentProcess(), TOKEN_ALL_ACCESS, out hToken))
            {
                //throw new Win32Exception(Marshal.GetLastWin32Error());
            }

            var sa = new SECURITY_ATTRIBUTES();
            sa.bInheritHandle = true;
            sa.Length = Marshal.SizeOf(sa);

            if (!DuplicateTokenEx(hToken, 268435456, ref sa, 1, 1, out hTokenDup))
            {
                var error = Marshal.GetLastWin32Error();
                CloseHandle(hToken);
                //throw new Win32Exception(error);
            }

            var si = new STARTUPINFO();
            si.cb = Marshal.SizeOf(si);

            if (!showWindow)
            {

                CloseHandle(hToken);
                CloseHandle(hTokenDup);
                //throw new Win32Exception(error);
            }

            if (pEnv != IntPtr.Zero)
            {
                DestroyEnvironmentBlock(pEnv);
            }

            CloseHandle(hToken);
            CloseHandle(hTokenDup);
        }

            public int dwProcessID;

            public int dwThreadID;
        }
    }

调用：SoftStart.Start(path,true);path是你要启动的exe地址，true是要显示ui。

具体项目源码：https://files.cnblogs.com/files/dachuang/WindowsServiceTest.zip?t=1658840431，用的是vs2019.

制作完本地服务项目后，需要在主程序安装和启动此服务，代码如下：

//调用安装并启动本地服务
LocalServiceMgr lsm = new LocalServiceMgr();
lsm.CheckService("eams-protect");//服务名

public class LocalServiceMgr
    {
        public void CheckService(string serviceName)
        {
            ServiceController[] services = ServiceController.GetServices();
            foreach (ServiceController s in services)
            {
                if (s.ServiceName == serviceName)
                {
                    if (s.Status == ServiceControllerStatus.Running || s.Status == ServiceControllerStatus.StartPending)
                        return;
                    else
                    {
                        s.Start();
                        return;
                    }
                }
            }
            Start();
        }

        /// <summary>
        /// 安装并启动本地守护服务
        /// </summary>
        /// <returns></returns>
        public bool Start()
        {
            Common.LogHelper.getLogHelper().WriteLog("开始安装开启服务");
            try
            {
                //创建启动对象
                ProcessStartInfo startInfo = new ProcessStartInfo();
                startInfo.WorkingDirectory = AppDomain.CurrentDomain.BaseDirectory+ "LocalService\\";
                startInfo.UseShellExecute = false;
                startInfo.CreateNoWindow = true;
                startInfo.FileName = AppDomain.CurrentDomain.BaseDirectory + "LocalService\\Install.bat";
                //设置启动动作,确保以管理员身份运行
                startInfo.Verb = "runas";
                Process.Start(startInfo);
                return true;
            }
            catch(Exception ex)
            {
                Common.LogHelper.getLogHelper().WriteLog("安装开启服务出错", ex);
                return false;
            }
        }
        /// <summary>
        /// 卸载本地守护服务
        /// </summary>
        /// <returns></returns>
        public bool Stop()
        {
            try
            {
                //创建启动对象
                System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();
                startInfo.WorkingDirectory = AppDomain.CurrentDomain.BaseDirectory;
                startInfo.UseShellExecute = false;
                startInfo.FileName = AppDomain.CurrentDomain.BaseDirectory + "LocalService\\Uninstall.bat";
                //设置启动动作,确保以管理员身份运行
                startInfo.Verb = "runas";
                Process.Start(startInfo);
                return true;
            }
            catch
            {
                return false;
            }
        }
    }

 里面的InstallUtil是windows自带的有，百度查下吧。没时间了，先写到这。
