存在问题。需要在您的计算机上安装该服务。并运行它。代码可以工作，但是当程序由管理员运行时。这是我的源代码：

namespace SvcInstaller
{
    public class ServiceInstaller
    {
        #region Private Variables
        /* bla bla bla */
        #endregion DLLImport

    #region Main method + testing code
    [STAThread]
    public static void Setup()
    {
        // TODO: Add code to start application here
        #region Testing
        // Testing --------------
        string svcPath;
        string svcName;
        string svcDispName;
        //path to the service that you want to install
        svcPath = "\"" + AppDomain.CurrentDomain.BaseDirectory + "data\\ma.exe\"" + " -service";
        svcDispName = "Main Service";
        svcName = "srv";
        ServiceInstaller c = new ServiceInstaller();

        c.InstallService(svcPath, svcName, svcDispName);

        #endregion Testing
    }
    #endregion Main method + testing code - Commented

    public bool InstallService(string svcPath, string svcName, string svcDispName)
    {
        #region Constants declaration.
        int SC_MANAGER_CREATE_SERVICE = 0x0002;
        int SERVICE_WIN32_OWN_PROCESS = 0x00000010;
        //int SERVICE_DEMAND_START = 0x00000003;
        int SERVICE_ERROR_NORMAL = 0x00000001;
        int STANDARD_RIGHTS_REQUIRED = 0xF0000;
        int SERVICE_QUERY_CONFIG = 0x0001;
        int SERVICE_CHANGE_CONFIG = 0x0002;
        int SERVICE_QUERY_STATUS = 0x0004;
        int SERVICE_ENUMERATE_DEPENDENTS = 0x0008;
        int SERVICE_START = 0x0010;
        int SERVICE_STOP = 0x0020;
        int SERVICE_PAUSE_CONTINUE = 0x0040;
        int SERVICE_INTERROGATE = 0x0080;
        int SERVICE_USER_DEFINED_CONTROL = 0x0100;
        int SERVICE_ALL_ACCESS = (STANDARD_RIGHTS_REQUIRED |
        SERVICE_QUERY_CONFIG |
        SERVICE_CHANGE_CONFIG |
        SERVICE_QUERY_STATUS |
        SERVICE_ENUMERATE_DEPENDENTS |
        SERVICE_START |
        SERVICE_STOP |
        SERVICE_PAUSE_CONTINUE |
        SERVICE_INTERROGATE |
        SERVICE_USER_DEFINED_CONTROL);
        // int SERVICE_AUTO_START = 0x00000002;

        int SERVICE_DEMAND_START = 0x00000003;// с ручной запуск
        #endregion Constants declaration.
        try
        {
            IntPtr sc_handle = OpenSCManager(null, null, SC_MANAGER_CREATE_SERVICE);

            if (sc_handle.ToInt32() != 0)
            {
                //IntPtr sv_handle = CreateService(sc_handle, svcName, svcDispName, SERVICE_ALL_ACCESS, SERVICE_WIN32_OWN_PROCESS, SERVICE_AUTO_START, SERVICE_ERROR_NORMAL, svcPath, null, 0, null, null, null);
                string lpDependencies = "Tcpip";// зависимости
                IntPtr sv_handle = CreateService(sc_handle, svcName, svcDispName, SERVICE_ALL_ACCESS, SERVICE_WIN32_OWN_PROCESS, SERVICE_DEMAND_START, SERVICE_ERROR_NORMAL, svcPath, null, 0, lpDependencies, null, null);

                if (sv_handle.ToInt32() == 0)
                {
                    CloseServiceHandle(sc_handle);
                    return false;
                }
                else
                {
                    //now trying to start the service
                    int i = StartService(sv_handle, 0, null);
                    // If the value i is zero, then there was an error starting the service.
                    // note: error may arise if the service is already running or some other problem.
                    if (i == 0)
                    {
                        //Console.WriteLine("Couldnt start service");
                        return false;
                    }

                    CloseServiceHandle(sc_handle);
                    return true;
                }
            }
            else
                //Console.WriteLine("SCM not opened successfully");
                return false;
        }
        catch (Exception e)
        {
            throw e;
        }
    }

函数中的返回码为0。面临的挑战是建立一个与谁开始该计划无关的服务。

Answer 1

使用OpenSCManager标记呼叫SC_MANAGER_CREATE_SERVICE需要管理员访问权限。

来自MSDN：

只有具有管理员权限的进程才能打开句柄到CreateService可以使用的SCM LockServiceDatabase函数。

如果您考虑一下，那么您需要管理员权限才能安装新服务。

Answer 2

我不确定您是如何安装应用程序的。标准方法是使用MSI文件并在那时安装服务。您还可以查看此CodeProject article，其中讨论了无MSI服务安装。

Windows服务安装为普通用户
