Как отправить пользовательские команды в службу C#

Question

Я пользуюсь службой Windows и формой Windows. Я пытаюсь отправить пользовательские команды в службу, чтобы создать изолированный файл хранилища. Однако, когда я нажимаю мой «btnSubmit», файл не создается. По какой-то причине это не похоже, чтобы выполнить команду

Я думаю, вам нужно добавить ServieControllerPermission:

ServiceController sc = new ServiceController("YOURServiceName", Environment.MachineName); 
ServiceControllerPermission scp = new ServiceControllerPermission(ServiceControllerPermissionAccess.Control, Environment.MachineName, "YOURServiceName");//this will grant permission to access the Service 
scp.Assert(); 
sc.Refresh(); 

sc.ExecuteCommand((int)YourMethods.methodX);
