在Windows的ServiceController权限7 [英] ServiceController permissions in Windows 7

问题描述

我有它由一个服务和一个可执行的应用程序。本质上，它是一种形式的应用程序，负责启动和在特定情况下停止服务。

I have an application which consists of a service and an executable. Essentially it's a forms application that is responsible for starting and stopping a service under specific circumstances.

在Windows XP中使用下列code中的应用程序管理这一优良：

On Windows XP the application manages this fine using the following code:

ServiceController controller = new ServiceController();
controller.MachineName = ".";
controller.ServiceName = "XXXXXXXXXX";
controller.Stop();
controller.WaitForStatus(ServiceControllerStatus.Stopped, new TimeSpan(0, 0, 10));
controller.Start();

但在Windows 7中，即使我已经启动的应用程序作为管理员，我得到以下异常：

But on Windows 7, even though I've started the application as an administrator, I get the following exception:

System.InvalidOperationException: Cannot open XXXXXXXXXXXXX service on computer '.'. ---> System.ComponentModel.Win32Exception: Access is denied
   --- End of inner exception stack trace ---
   at System.ServiceProcess.ServiceController.GetServiceHandle(Int32 desiredAccess)
   at System.ServiceProcess.ServiceController.Start(String[] args)
   at System.ServiceProcess.ServiceController.Start()

有什么我可以做编程方式来解决此问题？

Is there anything I can do programmatically to resolve this?

推荐答案

当你说你启动应用程序作为管理员，你的意思下的Administrators组中的帐户，或通过UAC提示，要​​求管理员凭据？如果没有UAC凭据提示（或实际运行为管理员帐户，不属于Administrators组中的帐户），您的应用程序没有权限修改服务，所以你看到的例外是正确的。

When you say that you started the application as Administrator, do you mean under an account in the Administrators group, or via a UAC prompt that requests administrator credentials? Without the UAC credentials prompt (or actually running as the Administrator account, not an account within the Administrators group), your application does not have permissions to modify services, so the exception you're seeing is correct.

的例子code此位可以检查您的应用程序以管理员身份运行，如果没有，启动一个UAC提示。

This bit of example code can check if your application is running as an administrator, and if not, launch a UAC prompt.

public static class VistaSecurity
{
    public static bool IsAdministrator()
    {
        WindowsIdentity identity = WindowsIdentity.GetCurrent();

        if (null != identity)
        {
            WindowsPrincipal principal = new WindowsPrincipal(identity);
            return principal.IsInRole(WindowsBuiltInRole.Administrator);
        }

        return false;
    }

    public static Process RunProcess(string name, string arguments)
    {
        string path = Path.GetDirectoryName(name);

        if (String.IsNullOrEmpty(path))
        {
            path = Environment.CurrentDirectory;
        }

        ProcessStartInfo info = new ProcessStartInfo
        {
            UseShellExecute = true,
            WorkingDirectory = path,
            FileName = name,
            Arguments = arguments
        };

        if (!IsAdministrator())
        {
            info.Verb = "runas";
        }

        try
        {
            return Process.Start(info);
        }

        catch (Win32Exception ex)
        {
            Trace.WriteLine(ex);
        }

        return null;
    }
}
