I try to install and start MySQL service to run with my project.

1- I downloaded MySQL server 5.7.17 and configured it to as this tutorial : Manually Installing and Configuring MySQL 5.7 on Windows 10

2- i copied the MySQL Folder and put it inside my project folder (MyProject\bin\Debug\mysql)

3- using this code to install and start MySQL Service with custom name.

var serviceExists = ServiceController.GetServices().Any(s => s.ServiceName == "mysqlTests");
            if (!serviceExists)
            {
                ServiceProcessInstaller ProcesServiceInstaller = new ServiceProcessInstaller();
                ProcesServiceInstaller.Account = ServiceAccount.LocalSystem;
                ProcesServiceInstaller.Username = null;
                ProcesServiceInstaller.Password = null;

                ServiceInstaller ServiceInstallerObj = new ServiceInstaller();
                InstallContext Context = new System.Configuration.Install.InstallContext();
                String path = String.Format("/assemblypath={0}", "mysql/bin/mysqld.exe");
                String[] cmdline = { path };

                Context = new InstallContext("", cmdline);
                ServiceInstallerObj.Context = Context;
                ServiceInstallerObj.DisplayName = "mysqlTests";
                ServiceInstallerObj.Description = "MySQL";
                ServiceInstallerObj.ServiceName = "mysqlTests";
                ServiceInstallerObj.StartType = ServiceStartMode.Automatic;
                ServiceInstallerObj.Parent = ProcesServiceInstaller;

                System.Collections.Specialized.ListDictionary state = new System.Collections.Specialized.ListDictionary();
                ServiceInstallerObj.Install(state);

            }

            ServiceController controller = new ServiceController();
            controller.ServiceName = "mysqlTests";
            if (controller.Status == ServiceControllerStatus.Stopped)
            {
                // Start the service
                controller.Start();
            }

i think the service installed successfully but this error appear : $exception {"Cannot start service mysqlTests on computer '.'."} System.InvalidOperationException Win32Exception: The system cannot find the file specified

as the attachment image: the service name seem to be installed


UPDATE:i update the code :

string appPath = Path.GetDirectoryName(Application.ExecutablePath);
 String path = String.Format("/assemblypath={0}", appPath + @"\mysql\bin\mysqld");

the error :
System.InvalidOperationException: 'Cannot start service mysqlTests on computer '.'.'
Win32Exception: The service did not respond to the start or control request in a timely fashion

What I have tried:

I tried to install the service manually with the command :

mysqld --install mysqlTests

the Service successfully installed.

and successfully start

E:\MyProject\bin\Debug\mysql\bin>net start mysqlTests

I don't know what I can do to make my code install and start MySQL service successfully
